Parallel Session: SG4 - GP-B and Lense-Thirring Measurements

Description: This session will provide the most extensive account to date of the technologies and scientific results of the Gravity Probe B test of GR. Essential was the apt conjunction of space, cryogenic, and advanced control technologies. Detailed accounts will be given of the orbiting gyroscopes, cryogenic star-tracker, dewar, and unique attitude/translational control system using the boiloff gas from the dewar. An important presentation will cover lessons learned for future missions such as LISA and STEP. Three science analysis papers validate the GR findings with numerous internal and external cross checks. The theoretical introduction will relate GP-B’s Lense-Thirring measurement to the wider relevance of frame-dragging to cosmology, black hole physics, and Mach's principle.

Parallel Session: OC3 - Cosmology from GRBs

Description: Gamma-Ray Bursts (GRBs) are the biggest explosions in the universe. Using the prompt emissions and the following afterglows, we have already observed the highest redshift of z=8.3 (or 9.2 photometrically), which is comparable to the most distant galaxies. The aim of this parallel session is to focus on the application of GRBs as a "NEW" cosmological tool to probe first stars, re-ionization, metal production, star formation history, as well as dark energy and dark matter evolution, up to the early universe.

Neil ASHBY

Parallel Session: SG1 SG2 - GR around the Earth and the Sun

Description: The session deals with the recent advances in testing general relativity and alternative theories of gravitation around Earth and in the Solar System. This includes testing frame dragging and PPN gravitation with laser ranged satellites as well as with dedicated missions around Earth. Also important are the connections with geodesy and reference frames issues, now well known with the use of GPS. Testing general relativity in the framework of Solar System exploration is another important part, including the ongoing Cassini and the forthcoming BepiColombo. Modeling the dynamical environment of a probe in these different contexts is an important issue, and specific contributions in this direction are welcome. A special attention will be devoted moreover to tests of the Equivalence Principle. The verification of this cornerstone for many gravitational theories - in its various formulations - continues to be at the center of scientific interest, also for the potential impact that violations could have in our overall picture of the Universe.

Salvatore CAPOZZIELLO

Parallel Session: AT2 - Extended Theories of Gravity

Description: Extended Theories of Gravity can be considered a new paradigm to cure shortcomings of General Relativity at infrared and ultraviolet scales. They are an approach that, by preserving the undoubtedly positive results of Einstein's Theory, is aimed to address conceptual and experimental problems recently emerged in Astrophysics, Cosmology and High Energy Physics. In particular, the goal is to encompass, in a self-consistent scheme, problems like Inflation, Dark Energy, Dark Matter, Large Scale Structure and, first of all, to give at least an effective description of Quantum Gravity. The basic idea of such an approach is to generalize the Hilbert-Einstein action relaxing the hypothesis that it must be linear in the Ricci scalar R. In principle, any f(R) function of R or other curvature invariants like Ricci, Riemann or Weyl tensors can be considered assuming effective theories of gravity. The general philosophy is that the true and final theory of gravity could be reconstructed, in principle, matching the phenomenology from infrared scales (astrophysics and cosmology) to ultraviolet scales (quantum field theory) going beyond a trial and error approach.

Parallel Session: BH4 - Black Hole Evaporation, Holographic Principle, and Entropic Gravity

Description: 38 years after the seminal discovery of Hawking evaporation of black holes, the notion remains in the frontiers of physics both with regard to the effect itself and the exciting new developments borne from it. The critical issues include the back-reaction and end-life of BH evaporation, alternative approaches to the Hawking effect, acoustic analog of Hawking evaporation, connections between Bekenstein entropy, entanglement entropy, and holographic principle, aspects of entropic gravity, etc. This session serves as a forum for the discussion of these open questions.

Parallel Session: CB1 - CMB Experiments

Description: A new generation of CMB anisotropy and polarization experiments is currently operated using large arrays of detectors, boosting the sensitivity of the surveys to unprecedented levels. The two mainstream projects are observations of the polarization of the CMB, looking for the inflationary B-modes at large and intermediate angular scales, and fine-scale measurements of the Sunyaev-Zeldovich effect in clusters of galaxies. In addition, Gaussianity measurements and spectral anisotropy measurements can considerably boost the scientific exploitation of the CMB measurements.

Carlo DIONISI

Parallel Session: AP4 - News from LHC

Description:

  • Standard Model Higgs Search The LHC 's excellent performance in 2011 has brought tantalizing hints of a Standard Model Higgs boson. With almost 5 fb-1 of collected data, both the ATLAS and CMS experiments see an intriguing excess of events in the mass range around 125 GeV. However, to turn those hints into a discovery, or to rule out the Standard Model Higgs particle altogether, requires one more year of data. As such, everybody is looking forward to the upcoming 8 TeV run at the LHC, which will help to shed light on this vital issue. By the time of the MG13 Conference in Stockholm, LHC should provide ATLAS and CMS with 5 fb-1 of new data at 8 TeV center of mass energy. That is to say, in this parallel session the experiments will be able to state whether a Higgs particle exists or not. Either would be a major advance in our exploration of nature, bringing us closer to understanding how the particles acquire their mass.
  • Searches for Dark Matter, SUSY and other exotic particles The fact that so far SUSY and other new physics signals have not appeared in "obvious" places is bringing a healthy excitement to the high energy physics community. With the 2012 LHC data, experiments will concentrate on searches for exotic particles that might decay into yet unexplored modes. In the meantime, they are setting unprecedented boundaries to regions where new particles (not just SUSY) could exist. The results of what particle accelerators can bring to enlighten the mystery of Dark Matter will also be presented and discussed.
  • B rare decays The LHCb Collaboration will test the Standard Model predictions with an unprecedented precision and put limits on possible deviations due to new physics, by studying in particular rare decays: yet undiscovered particles could leave their footprint by modifying the decay rate and other physics parameters. Deviations from values predicted by the Standard Model – the established set of physics theories that describes and encompasses a large variety of natural phenomena – could point scientists to the existence of new territories.
  • Probing the nature of heavy-ion collisions The ALICE experiment will present recent results on their investigations into the intriguing nature of the Quark Gluon Plasma (QGP).

Parallel Session: AT4 - Modified Gravity

Description: General relativity is definitely a beautiful theory of gravitation. However, we may have alternative approaches to explain various gravitational phenomena. Also, we are faced with big mysteries in the Universe such as dark energy and dark matter, which might be solved by a new theory of gravitation. The aim of this parallel session is to discuss such alternative approaches to gravitation. Those include, but are not restricted to, scalar-tensor theories, massive gravity, Higgs phases of gravity, as well as string theory, gravity at Lifshitz point, higher dimensions, braneworld scenarios, and higher-curvature theories.

Parallel Session: ST3 - Multivalued Fields for Defects in Spacetime and Gravity

Description: Session will be devoted to multivalued field theories and the geometric theory of defects. Defects in elastic media specity the plastic properties of solids, and their theoretical description is of great importance for material science. If defects are present, the basic variables of elasticity theory (the displacement vector field and the rotational angle field) become multivalued. Certain higher derivatives of these fields, however, remain single-valued and define a Riemann-Cartan geometry that accommodates natrually a theory of gravity with torsion, in which curvature and torsion are built from rotational and translational defects. Since these two defects are dependent of each other, physical phenomena possess equivalent descriptions, the most famous example being Einstein's teleparallel theory of gravity.

Parallel Session: GRB2 - First minutes of GRBs: physics of prompt emission, central engine, and progenitor

Description: Although significant progress has been made toward our understanding of GRB afterglow, the physics of GRB prompt emission, central engine, and progenitor is still poorly understood. Recent observations led by Fermi and Swift have revealed puzzling observational facts that call for a rethinking of the theoretical framework. This session will gather observers and theorists to discuss the first several minutes of GRBs. Topics include lightcurves, spectra, polarization properties of prompt emission and early afterglows, composition of the GRB ejecta, mechanisms of energy dissipation, particle acceleration, and radiation, as well as observational signatures of the GRB central engine and the progenitor star.

Claus LAEMMERZAHL

Parallel Session: EG1 - Experimental Gravitation

Description: General Relativity (GR) is based on the Einstein Equivalence Principle (EEP). Accordingly, the first class of experiments searching for deviations from GR test the various aspects of the EEP. If the EEP is fulfilled gravity is described by a metric theory. Therefore, the other class of experiments/observations is related to the question how the space-time metric can be determined from the matter. Within GR this is given by the Einstein field equations. Deviations from that can be parametrized by the PPN parameters. Many astrophysical observations and space experiments are devoted to better estimates for these PPN parameters. This session is covers all these laboratory and space tests and astronomical observations. Also tests with quantum matter are included.

Jerzy LEWANDOWSKI

Parallel Session: QG1 - Loop Quantum Gravity, Quantum Geometry, Spin Foams

Description: Loop Quantum Gravity (LQG), a framework suited to quantize general relativity, has seen rapid progress in the last three years. The results achieved strongly suggest that the goal of finding a working and predictive quantum theory of gravity is within reach. For specific kinds of matter couplings, a way to drastically simplify the dynamics and its physical interpretation has been discovered. It gives rise to a set of examples of theories of gravity coupled to the fields in which the canonical quantization scheme can be completed. Independently, there have been important breakthroughs in the path integral formulation of the theory related to the so called Spin Foam Models. The session will review the results of canonical Loop Quantum Gravity and Spin Foam Models with the emphasis on the models admitting local degrees of freedom without the symmetry (or any other) reduction. Related approaches to quantum gravity will be also welcome. The common theme is the background independent quantization of Einstein's gravity and the occurrence of quantum geometry.

According to the magnetar model, they consist of isolated neutron stars whose impulsive and persistent electromagnetic emission is powered by magnetic energy. Aim of this Parallel Session is to discuss the most recent observational and theoretical results on AXP/SGR, with an emphasis on their connections with other relativistic objects, and taking advantage of constructive scrutiny of alternative explanations.

Parallel Session: GW2 - Gravitational Wave and Multimessenger Astronomy

Description: This section is devoted to review and discuss the multi-messenger approach, incorporating gravitational waves, X and gamma-rays, neutrinos and wide field optical observations. We will focused the attention on the recent GW astrophysics results, data analysis, methods and search ideas that aim to detect or set limit on astrophysical sources that emit in multiple channels such as electromagnetic and particle channels as well as in gravitational waves. Multimessenger astronomy using gravitational waves currently follow three main strategies, gravitational-wave searches triggered by non GW detectors as gamma-ray and neutrinos, electromagnetic follow-ups of gravitational wave candidate events, and approaches where all messengers are used on more or less equal base. In addition, in this section, multimessenger concepts and phenomenological studies incorporating present work, expected results, or innovative ideas for the future from combination of electromagnetic, particle and GW detectors are very welcome.

Parallel Session: TC1 - Supermassive Black Holes in Cosmic Structure Formation: Nature and Origin
TC2 - Supermassive Black Holes in Cosmic Structure Formation: Coalescence and Effect on Galaxy Formation

Description: Supermassive black holes (SMBHs) are ubiquitous at the center of galaxies, the prime example being our own Milky Way. They are thought to be present already less than a billion year after the Big Bang, probably contributing to how galaxies themselves develop. Mergers of SMBHs should result in the loudest gravitational wave signals, providing a powerful way to test General Relativity. Yet the origin and co-evolution of SMBHs with the host galaxies, including modes and timescales of black hole mergers, are still poorly understood. Likewise, the energy feedback of SMBHs, resulting from radiative losses in the accretion flow, is assumed to have a key role in shaping galaxy evolution but the actual mechanism of energy transfer is unclear. In this extended parallel session we will discuss these different but interconnected topical issues, confronting the latest ideas and models and trying to bridge different areas of research such as cosmic structure formation and numerical relativity calculations of SMBH mergers.

Parallel Session: SF1 - Origin and physics of Soft Gamma-ray Repeaters and Anomalous X-ray Pulsars

Description: Soft Gamma-ray Repeaters (SGR) and Anomalous X-ray Pulsars (AXP) are likely to contain some of the strongest magnetic fields in the Universe. According to the magnetar model, they consist of isolated neutron stars whose impulsive and persistent electromagnetic emission is powered by magnetic energy. Aim of this Parallel Session is to discuss the most recent observational and theoretical results on AXP/SGR, with an emphasis on their connections with other relativistic objects, and taking advantage of constructive scrutiny of alternative explanations.

Parallel Session: EG4 - Self-Gravitating System

Description: Galaxy nuclei and the cores of globular clusters are regions where the density of stars can reach millions per cubic parsec. Modeling the dynamical evolution of such systems is critical for understanding a number of fundamental processes, including core collapse, the creation of massive black holes, and the generation of gravitational waves. But the computational challenges are severe, due to the large range in time scales; the steepness of gravitational force gradients near a massive compact object; the need to include relativistic corrections to the equations of motion; and finite-size (collisional) effects, among other factors. This session will focus on recent progress in this area.

Parallel Session: CM4 - Quantum Cosmology and Quantum Effects in the Early Universe

Description: In this session I propose, besides regular talks, to bring a discussion on selecting challenges for quantum cosmology, as an opportunity to (re-) introduce enticing problems to interested researchers. Depending on the number of talks we could, eg, split the 4 hours into two sets of, say, 1h30-2h, more or less, with one such slot for 10m talks and the other for a discussion on, eg, quantum cosmology potential 'new' directions.

Parallel Session: AT4 - Modified Gravity

Description: General relativity is definitely a beautiful theory of gravitation. However, we may have alternative approaches to explain various gravitational phenomena. Also, we are faced with big mysteries in the Universe such as dark energy and dark matter, which might be solved by a new theory of gravitation. The aim of this parallel session is to discuss such alternative approaches to gravitation. Those include, but are not restricted to, scalar-tensor theories, massive gravity, Higgs phases of gravity, as well as string theory, gravity at Lifshitz point, higher dimensions, braneworld scenarios, and higher-curvature theories.

Parallel Session: SG1 SG2 - GR around the Earth and the Sun

Description: The session deals with the recent advances in testing general relativity and alternative theories of gravitation around Earth and in the Solar System. This includes testing frame dragging and PPN gravitation with laser ranged satellites as well as with dedicated missions around Earth. Also important are the connections with geodesy and reference frames issues, now well known with the use of GPS. Testing general relativity in the framework of Solar System exploration is another important part, including the ongoing Cassini and the forthcoming BepiColombo. Modeling the dynamical environment of a probe in these different contexts is an important issue, and specific contributions in this direction are welcome. A special attention will be devoted moreover to tests of the Equivalence Principle. The verification of this cornerstone for many gravitational theories - in its various formulations - continues to be at the center of scientific interest, also for the potential impact that violations could have in our overall picture of the Universe.

Parallel Session: GW2 - Gravitational Wave and Multimessenger Astronomy

Description: This section is devoted to review and discuss the multi-messenger approach, incorporating gravitational waves, X and gamma-rays, neutrinos and wide field optical observations. We will focused the attention on the recent GW astrophysics results, data analysis, methods and search ideas that aim to detect or set limit on astrophysical sources that emit in multiple channels such as electromagnetic and particle channels as well as in gravitational waves. Multimessenger astronomy using gravitational waves currently follow three main strategies, gravitational-wave searches triggered by non GW detectors as gamma-ray and neutrinos, electromagnetic follow-ups of gravitational wave candidate events, and approaches where all messengers are used on more or less equal base. In addition, in this section, multimessenger concepts and phenomenological studies incorporating present work, expected results, or innovative ideas for the future from combination of electromagnetic, particle and GW detectors are very welcome.

Parallel Session: GRB1 - Photospheric Emission in GRBs

Description: Early models of cosmological GRBs predicted the observed spectrum to be nearly blackbody. Observations were at odds with this prediction, and different theoretical models assuming optically thin emission have been put forward. However, models of such non thermal emission appear to be inconsistent with observations of steep spectra in early phases of many GRBs. Instead models involving photospheric emission producing modifed blackbody spectra explain such observed spectra quite naturally. We plan to discuss physical aspects of photospheric emission in ultrarelativistic sources as well as observational issues related to the detection of such a photospheric component in GRBs. Special attention is expected to be given to sub-photospheric dissipation mechanisms, geometric and dynamical effects, jet content, and additional components in the observed spectrum.

Parallel Session: SO4 - White Dwarf Pulsars and Rotating White Dwarf Theory

Description: Pulsars are conventionally considered to be rotating neutron stars, which have been regarded as a textbook case of particle acceleration site emitting radiation in the wide energy band. Pulsars are the very simple system, rotating magnets. White dwarfs, having the same structures of magnetospheres as neutron stars, can have such activities. “Why we do not have White Dwarf Pulsars (WDP) when we have many kinds of neutron star pulsars” is a basic question in rotating magnetic compact objects. Recently, several observational approaches to search for white dwarf pulsars are performed in high energy photon bands. The aims of this section are 1) to focus on current results and future prospects of WDP observations and 2) to discuss on the particle acceleration process, emission mechanisms, and structures of magnetosphere etc of WDP in comparison with neutron-star pulsar cases.

Parallel Session: SF3 - Strong Fields and High Energy Astrophysical events

Description: This session is dedicated to the all aspects of high energy phenomena due to strong electromagnetic fields in astrophysical environments. The electromagnetic effects are studied in the black hole formation; in compact objects; and in jets. The study of electromagnetic fields in gravitational collapse is gaining renewed impulse because it is already known that high intensity fields could be generated in the collapsing matter, on the other hand the compact objects can have intense electric fields. The keywords list is (although the list is flexible): electron-positron pair creation and plasma; oscillatory electromagnetic fields; charged particle acceleration; strong electromagnetic radiation fields; electric fields in compact objects; charged core collapse; Einstein-Maxwell spacetimes; stellar gravitational collapse; Reissner-Nördstrom black holes; Kerr-Newman black holes.

Parallel Session: OC3 - Cosmology from GRBs

Description: Gamma-Ray Bursts (GRBs) are the biggest explosions in the universe. Using the prompt emissions and the following afterglows, we have already observed the highest redshift of z=8.3 (or 9.2 photometrically), which is comparable to the most distant galaxies. The aim of this parallel session is to focus on the application of GRBs as a "NEW" cosmological tool to probe first stars, re-ionization, metal production, star formation history, as well as dark energy and dark matter evolution, up to the early universe.

Parallel Session: GRB2 - First minutes of GRBs: physics of prompt emission, central engine, and progenitor

Description: Although significant progress has been made toward our understanding of GRB afterglow, the physics of GRB prompt emission, central engine, and progenitor is still poorly understood. Recent observations led by Fermi and Swift have revealed puzzling observational facts that call for a rethinking of the theoretical framework. This session will gather observers and theorists to discuss the first several minutes of GRBs. Topics include lightcurves, spectra, polarization properties of prompt emission and early afterglows, composition of the GRB ejecta, mechanisms of energy dissipation, particle acceleration, and radiation, as well as observational signatures of the GRB central engine and the progenitor star.
