Title |
DM haloes in spheroidal galaxies with prevalence of radial component in the velocity profile | |||||
| Coauthors | ||||||||
|
Abstract |
This presentation is dedicated to the study of dark matter haloes in self-gravitating spherical systems (Dwarf galaxies, E0-E1 Elliptical galaxies) and in Spiral galaxies. The study has been developed from a statistical point of view, assuming different anisotropic distribution functions (DFs) for the dark component of the system, both in classical and quantum regime, changing the energy distribution and maintaining the same anisotropic factor. These DFs generate velocity profiles with a prevalence of radial component and peacked density profiles. We investigate also the effect of these DM distributions on the stars velocity profiles and their distribution, the limits on the DM masses, comparing and contrasting the results with other models. |

Title |
Neutrino emission from GRBs | |||||
| Coauthors | ||||||||
|
Abstract |
This presentation is dedicated to the study of neutrino emission result from GRBs. The study take into account the different flavors of neutrinos (principally muonic- and electronic-neutrino), created by the decay of charged pions and muons resulting by a proton-proton collision, in different moments of the GRB evolution. Two protons energy distributions were considered: a monochromatic one and a Boltzmann-like one. We have also studied the photons flux and luminosity from pi-0 decay created in the same p-p collision. Finally, it has been investigated the possibility to detect these neutrinos means some Neutrino Detectors on the Earth. |
