Constraining the Konoplya-Rezzolla-Zhidenko deformation parameters II: limits from stellar-mass black hole X-ray data
Zhibo Yu, Qunfeng Jiang, Askar B. Abdikamalov +5
Astrophysical black holes are thought to be the Kerr black holes predicted by general relativity, but macroscopic deviations from the Kerr solution can be expected from a number of…
Constraining the KRZ deformation parameters I: limits from supermassive black hole X-ray data
Askar B. Abdikamalov, Dimitry Ayzenberg, Cosimo Bambi +2
X-ray reflection spectroscopy is a powerful technique for probing the nature of gravity around black holes in the so-called strong field regime. One of the most popular of such pro…
Testing the Weak Equivalence Principle near black holes
Rittick Roy, Askar B. Abdikamalov, Dimitry Ayzenberg +3
Today we have quite stringent constraints on possible violations of the Weak Equivalence Principle from the comparison of the acceleration of test-bodies of different composition i…
Constraints on Einstein-Maxwell dilaton-axion gravity from X-ray reflection spectroscopy
Ashutosh Tripathi, Biao Zhou, Askar B. Abdikamalov +2
Einstein-Maxwell dilaton-axion gravity is a string-inspired model arising from the low energy effective action of heterotic string theory and an important candidate as alternative…
Impact of the disk thickness on X-ray reflection spectroscopy measurements
Ashutosh Tripathi, Askar B. Abdikamalov, Dimitry Ayzenberg +2
In a previous paper, we presented an extension of our reflection model RELXILL_NK to include the finite thickness of the accretion disk following the prescription in Taylor & Reyno…
Probing the near-horizon region of Cygnus X-1 with Suzaku and NuSTAR
Zuobin Zhang, Honghui Liu, Askar B. Abdikamalov +3
Astrophysical black holes are ideal laboratories for testing Einstein's theory of general relativity in the strong field regime. In this manuscript, we present an analysis of Suzak…
