A model for the polarization of the high-energy radiation from accreting black holes: the case of XTE J1118+480
Florencia L. Vieyro, Gustavo E. Romero, Sylvain Chaty
The high-energy emission ( keV MeV) of Cygnus X-1 --the most well-studied Galactic black hole-- was recently found to be strongly polarized. The origin of this radiation…
Chandra Observations of Eight Sources Discovered by INTEGRAL
John A. Tomsick, Roman Krivonos, Qinan Wang +5
We report on 0.3-10 keV observations with the Chandra X-ray Observatory of eight hard X-ray sources discovered within 8 degrees of the Galactic plane by the INTEGRAL satellite. The…
High Mass X-ray Binaries: Progenitors of double neutron star systems
Sylvain Chaty
In this review I briefly describe the nature of the three kinds of High-Mass X-ray Binaries (HMXBs), accreting through: (i) Be circumstellar disc, (ii) supergiant stellar wind, and…

Investigating the nature of IGR J17454-2919 using X-ray and Near-Infrared observations
A. Paizis, M. A. Nowak, J. Rodriguez +7
IGR J17454-2919 is a hard X-ray transient discovered by INTEGRAL on 2014 September 27. We report on our 20ks Chandra observation of the source, performed about five weeks after the…
Infrared study of H1743-322 in outburst: a radio-quiet and NIR-dim microquasar
S. Chaty, A. J. Muñoz Arjonilla, G. Dubus
The X-ray binary, black hole candidate, and microquasar H1743-322 exhibited a series of X-ray outbursts between 2003 and 2008. We took optical/infrared (OIR) observations with the…
