Radiative GRMHD simulations of puffy accretion discs: Numerical versus analytical models of sub-Eddington accretion
Debora Lančová, Maciek Wielgus, Marek Abramowicz +6
A widely accepted picture of an accretion flow in the luminous soft spectral state of X-ray binary systems is a geometrically thin disc structure much like the classic analytic sol…

Broad Iron Line as a Relativistic Reflection from Warm Corona in AGN
P. P. Biswas, A. Różańska, F. H. Vincent +2
We present that the broad feature usually observed in X-ray spectra can be explained by a ray-traced emission from a two-slab system containing a dissipative, warm corona on top of…

X-ray polarization of reflected thermal emission
J. Podgorný, M. Dovčiak, R. Goosmann +5
We compute rest-frame reflection spectra and the corresponding energy-dependent linear polarization degree and angle for (un)polarized single-temperature blackbody spectra impingin…
