The spins of the Galactic black holes in MAXI J1535-571 and 4U 1630-472 from Insight-HXMT
Qichun Liu, Honghui Liu, Cosimo Bambi +1
Insight-HXMT is the first Chinese X-ray astronomical mission. With a 1-250 keV bandpass, an energy resolution of 150 eV at 6 keV, and without being subject to pile-up distortions,…
A reflection model with a radial disk density profile
Askar B. Abdikamalov, Dimitry Ayzenberg, Cosimo Bambi +2
In this paper we present RELXILLDGRAD_NK, a relativistic reflection model in which the electron density of the accretion disk is allowed to have a radial power-law profile. The ion…
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…
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…
Testing the Kerr black hole hypothesis with GRS 1716-249 by combining the continuum-fitting and the iron-line methods
Zuobin Zhang, Honghui Liu, Askar B. Abdikamalov +3
The continuum-fitting and the iron-line methods are currently the two leading techniques for measuring the spins of accreting black holes. In the past few years, these two methods…
A Highly Accreting Low-Mass Black Hole Hidden in the Dust: Suzaku and NuSTAR observations of the NLS1 Mrk 1239
Jiachen Jiang, Mislav Baloković, Murray Brightman +3
We present torus modelling for the X-ray spectra of a nearby narrow-line Seyfert 1 galaxy Mrk 1239 (), based on archival Suzaku, NuSTAR and Swift observations. Our model…
