Interaction between disk and extended corona in a general relativistic framework
Sudeb Ranjan Datta, Michal Bursa, Michal Dovciak +1
The energy equilibrium between the corona and the underlying disk in a two-phase accretion flow sets a lower limit on the achievable photon index. A slab corona may not explain the…
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…
First X-ray polarization measurement confirms the low black-hole spin in LMC X-3
Jiří Svoboda, Michal Dovčiak, James F. Steiner +109
X-ray polarization is a powerful tool to investigate the geometry of accreting material around black holes, allowing independent measurements of the black hole spin and orientation…
Accretion Disc Evolution in GRO J1655-40 and LMC X-3 with Relativistic and Non-Relativistic Disc Models
Anastasiya Yilmaz, Jiri Svoboda, Victoria Grinberg +3
Black hole X-ray binaries are ideal environments to study the accretion phenomena in strong gravitational potentials. These systems undergo dramatic accretion state transitions and…
Testing Relativistic Accretion Disk Models with GRO J1655-40
Anastasiya Yilmaz, Jiri Svoboda, Victoria Grinberg +3
Black hole X-ray binaries are ideal environments to test the accretion phenomena in the presence of strong gravitational potentials. KERRBB held an important place in the X-ray spe…
