Testing relativistic reflection models with GRMHD simulations of accreting black holes
Swarnim Shashank, Shafqat Riaz, Askar B. Abdikamalov +1
X-ray reflection spectroscopy is currently one of the leading techniques for studying the inner part of accretion disks around black holes, measuring black hole spins, and even tes…
Impact of ionization and electron density gradients in X-ray reflection spectroscopy measurements
Gitika Mall, Ashutosh Tripathi, Askar B. Abdikamalov +1
The models currently used for the analysis of the reflection spectra of black holes usually assume a disk with constant ionization and electron density. However, there is some deba…
Black Hole Spin Measurements Based on a Thin Disc Model with Finite Thickness I. An example study of MCG-06-30-15
Jiachen Jiang, Askar B. Abdikamalov, Cosimo Bambi +1
We present a re-analysis of the XMM-Newton and NuSTAR observing campaign for the well-studied, X-ray-bright AGN MCG-06-30-15. In particular, we consider a disc model with finite th…
Testing the Kerr black hole hypothesis with the continuum-fitting and the iron line methods: the case of GRS 1915+105
Ashutosh Tripathi, Askar B. Abdikamalov, Dimitry Ayzenberg +4
The continuum-fitting and the iron line methods are currently the two leading techniques for probing the strong gravity region around accreting black holes. In the present work, we…
Reflection spectra of accretion disks illuminated by disk-like coronae
Shafqat Riaz, Askar B. Abdikamalov, Dimitry Ayzenberg +3
Relativistic reflection features in the X-ray spectra of black hole binaries and AGNs are thought to be produced through illumination of a cold accretion disk by a hot corona. In t…
Supermassive black holes as possible sources of ultra high energy cosmic rays
Arman Tursunov, Zdeněk Stuchlík, Martin Kološ +2
Production and acceleration mechanisms of ultra-high-energy cosmic rays (UHECRs) of energy eV, clearly beyond the GZK-cutoff limit remain unclear that points to exotic na…
