Proper Motion and Natal Kick in the Galactic Black Hole X-ray Binary AT2019wey
Lang Cui, Pengfei Jiang, Tao An +9
Understanding the formation mechanisms of stellar-mass black holes in X-ray binaries (BHXBs) remains a fundamental challenge in astrophysics. The natal kick velocities imparted dur…
Investigating the consistency of the shape and flux of X-ray reflection spectra in the hard state with an accretion disk reaching close to the black hole
Sudeb Ranjan Datta, Michal Dovčiak, Michal Bursa +3
The observed spectra from black hole (BH) X-ray binaries (XRBs) typically consist of two primary components: multitemperature blackbody (BB) originating from the accretion disk in…
Inferring the iron K emissivity profiles of accretion discs irradiated by extended coronae
Wenda Zhang, Michal Dovčiak, Michal Bursa +2
One of the most promising methods to measure the spin of an accreting black hole is fitting the broad iron K line in the X-ray spectrum. The line profile also depends on the geo…
Discovery of X-ray Polarization from the Black Hole Transient Swift J1727.8-1613
Alexandra Veledina, Fabio Muleri, Michal Dovciak +113
We report the first detection of the X-ray polarization of the bright transient Swift J1727.8-1613 with the Imaging X-ray Polarimetry Explorer. The observation was performed at the…
Uncovering the geometry of the hot X-ray corona in the Seyfert galaxy NGC4151 with IXPE
V. E. Gianolli, D. E. Kim, S. Bianchi +106
We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy NGC4151. The source has been observed with the Imaging X-ray Polarimetry Explorer (IXPE) for 700 ks,…
X-ray Polarimetry as a Tool to Measure the Black Hole Spin in Microquasars: Simulations of IXPE Capabilities
Romana Mikusincova, Michal Dovciak, Michal Bursa +5
Measurements of the angular momentum (spin) of astrophysical black holes are extremely important, as they provide information on the black hole formation and evolution. We present…
