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 DovÄiak, 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…
