Fifty Years After the Discovery of the First Stellar-Mass Black Hole: A Review of Cyg X-1
Jiachen Jiang
Around 50 years ago, the famous bet between Stephen Hawking and Kip Thorne on whether Cyg X-1 hosts a stellar-mass black hole became a well-known story in the history of black hole…
Self-Consistent Disk-Reflection Analysis of the Black-Hole Candidate X-ray Binary MAXI J1813-095 with NICER, Swift, Chandra, and NuSTAR
Santiago Ubach, James F. Steiner, Jiachen Jiang +5
We present our analysis of MAXI J1813-095 during its hard state ``stalled'' outburst in 2018. This self-consistent analysis has been carried out using \NICER, \Swift, \Chandra, and…
Modeling reflection spectra of super-Eddington X-ray sources
Swarnim Shashank, Askar B. Abdikamalov, Honghui Liu +5
Relativistic reflection is a common feature in the X-ray observations of accreting compact objects. We present reflux, a new X-ray reflection model for spectral analysis of super-E…
Plunging region emission in the X-ray binary MAXI J0637430
Andrew Mummery, Jiachen Jiang, Andrew Fabian
On the second of November 2019 the black hole X-ray binary MAXI J0637430 went into outburst, at the start of which it was observed in a thermal ``disc-dominated'' state. High ph…
X-ray spectra of black hole X-ray binaries with returning radiation
Temurbek Mirzaev, Cosimo Bambi, Askar B. Abdikamalov +4
In the disk-corona model, the X-ray spectrum of a stellar-mass black hole in an X-ray binary is characterized by three components: a thermal component from a thin and cold accretio…
Variable ionized disk wind in MAXI J1803-298 revealed by NICER
Zuobin Zhang, Cosimo Bambi, Honghui Liu +7
We present the results from the NICER observation data of MAXI J1803-298 across the entire 2021 outburst. In the intermediate and soft state, we detect significant absorption lines…
The Origin of the X-ray Emission from the Non-Starburst Gas-Rich Luminous Infrared Galaxies Arp 302
Jiachen Jiang, William Baker, Andrew Young +1
We present an analysis of the XMM-Newton observation of luminous infrared merging galaxies Arp 302 and a joint re-analysis of its Chandra observation. In particular, we focus on th…
Towards more accurate synthetic reflection spectra: improving the calculations of returning radiation
Temurbek Mirzaev, Shafqat Riaz, Askar B. Abdikamalov +6
We present a new model to calculate reflection spectra of thin accretion disks in Kerr spacetimes. Our model includes the effect of returning radiation, which is the radiation that…
