Testing General Relativity with NuSTAR data of Galactic Black Holes
Ashutosh Tripathi, Yuexin Zhang, Askar B. Abdikamalov +5
Einstein's theory of General Relativity predicts that the spacetime metric around astrophysical black holes is described by the Kerr solution. In this work, we employ state-of-the-…
Testing evolution of LFQPOs with mass accretion rate in GRS 1915+105 with Insight-HXMT
Honghui Liu, Long Ji, Cosimo Bambi +5
Using the Insight-HXMT observations of GRS 1915+105 when it exhibits low frequency quasi-periodic oscillations (QPOs), we measure the evolution of the QPO frequency along with disk…
Towards precision measurements of accreting black holes using X-ray reflection spectroscopy
Cosimo Bambi, Laura W. Brenneman, Thomas Dauser +14
Relativistic reflection features are commonly observed in the X-ray spectra of accreting black holes. In the presence of high quality data and with the correct astrophysical model,…
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…
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…
