Impact of the reflection model on the estimate of the properties of accreting black holes

Ashutosh Tripathi, Honghui Liu, Cosimo Bambi

Relativistic reflection features in the X-ray spectra of black hole binaries and AGNs originate from illumination of the inner part of the accretion disk by a hot corona. In the pr…

X-ray reflection spectroscopy with Kaluza-Klein black holes

Jiachen Zhu, Askar B. Abdikamalov, Dimitry Ayzenberg +6

Kaluza-Klein theory is a popular alternative theory of gravity, with both non-rotating and rotating black hole solutions known. This allows for the possibility that the theory coul…

Thermal spectra of thin accretion disks of finite thickness around Kerr black holes

Menglei Zhou, Askar B. Abdikamalov, Dimitry Ayzenberg +3

The analysis of the thermal spectrum of geometrically thin and optically thick accretion disks of black holes, the so-called continuum-fitting method, is one of the leading techniq…

Testing the Kerr black hole hypothesis using X-ray reflection spectroscopy and a thin disk model with finite thickness

Askar B. Abdikamalov, Dimitry Ayzenberg, Cosimo Bambi +5

X-ray reflection spectroscopy is a powerful tool for probing the strong gravity region of black holes and can be used for testing general relativity in the strong field regime. Sim…

Testing general relativity with the stellar-mass black hole in LMC X-1 using the continuum-fitting method

Ashutosh Tripathi, Menglei Zhou, Askar B. Abdikamalov +6

The iron line and the continuum-fitting methods are currently the two leading techniques for measuring black hole spins with electromagnetic radiation. They can be naturally extend…

Search for traversable wormholes in active galactic nuclei using X-ray data

Ashutosh Tripathi, Biao Zhou, Askar B. Abdikamalov +2

In a previous paper, one of us calculated iron K line profiles emitted from possible accretion disks around traversable wormholes as a first step to use X-ray reflection spectro…
