Reflection features in the X-ray spectrum of Fairall 9 and implications for tests of general relativity
Honghui Liu, Haiyang Wang, Askar B. Abdikamalov +2
X-ray reflection spectroscopy is potentially a powerful tool to probe the spacetime geometry around astrophysical black holes and test general relativity in the strong field regime…
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…
Testing the Kerr hypothesis using X-ray reflection spectroscopy with NuSTAR data of Cygnus X-1 in the soft state
Honghui Liu, Askar B. Abdikamalov, Dimitry Ayzenberg +4
We continue exploring the constraining capabilities of X-ray reflection spectroscopy to test the Kerr-nature of astrophysical black holes and we present the results of our analysis…
XSPEC model for testing the Kerr black hole hypothesis using the continuum-fitting method
Menglei Zhou, Askar B. Abdikamalov, Dimitry Ayzenberg +3
We present NKBB, an XSPEC model for the thermal spectrum of thin accretion disks in parametric black hole spacetimes. We employ the Novikov-Thorne model for the description of the…
RELXILL_NK: a relativistic reflection model for testing Einstein's gravity
Cosimo Bambi, Askar B. Abdikamalov, Dimitry Ayzenberg +6
Einstein's theory of general relativity was proposed over 100 years ago and has successfully passed a large number of observational tests in the weak field regime. However, the str…
Distinguishing black holes and naked singularities with iron line spectroscopy
Honghui Liu, Menglei Zhou, Cosimo Bambi
It is commonly thought that the final product of gravitational collapse is a black hole. Nevertheless, theoretical studies have not yet provided a final answer to the question whet…
