Talk	Oral abstract	Title	Contribution of Black Hole X-Ray Binaries to the X-ray, FIR and Radio Cosmic Backgrounds
Coauthors
Abstract	I will discuss the possible X-ray, FIR and Radio backgrounds due to accreting stellar black holes in high mass X-ray binaries prolifically formed as remanents of Pop III stellar systems during the reionization epoch of the universe. (https://doi.org/10.1051/0004-6361/201016357)

Talk	Oral abstract	Title	The Formation of Stellar Black Holes: Sources of GWs
Coauthors
Abstract	It is believed that stellar black holes (BHs) can be formed in two different ways: Either a massive star collapses directly into a BH without a supernova (SN) explosion, or an explosion occurs in a proto-neutron star, but the energy is too low to completely unbind the stellar envelope, and a large fraction of it falls back onto the short-lived neutron star (NS), leading to the delayed formation of a BH. Theoretical models set progenitor masses for BH formation by implosion, namely, by complete or almost complete collapse, but observational evidences have been elusive. I will review the observational insights on BHs formed by implosion without large natal kicks from: (1) the kinematics in three dimensions of space of five Galactic BH X-ray binaries (BH-XRBs), (2) the diversity of optical and infrared observations of massive stars that collapse in the dark, with no luminous SN explosions, possibly leading to the formation of BHs, and (3) the sources of gravitational waves (GWs) produced by mergers of stellar BHs so far detected with LIGO. Multiple indications of BH formation without ejection of a significant amount of matter and with no natal kicks obtained from these different areas of observational astrophysics, and the recent observational confirmation of the expected dependence of BH formation on metallicity and redshift, are qualitatively consistent with the high merger rates of binary black holes (BBHs) inferred from the first detections with LIGO.
