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,…
A variable ionized disk wind in the black-hole candidate EXO 1846-031
Yanan Wang, Long Ji, Javier A. Garcia +88
After 34 years, the black-hole candidate EXO 1846-031 went into outburst again in 2019. We investigate its spectral properties in the hard intermediate and the soft states with NuS…
Evidence for Returning Disk Radiation in the Black Hole X-ray Binary XTE J1550-564
Riley M. T. Connors, Javier A. Garcia, Thomas Dauser +7
We explore the accretion properties of the black hole X-ray binary \j1550\ during its outbursts in 1998/99 and 2000. We model the disk, corona, and reflection components of X-ray s…
Studying the Reflection Spectra of the New Black Hole X-ray Binary Candidate MAXI J1631-479 Observed by NuSTAR: A Variable Broad Iron Line Profile
Yanjun Xu, Fiona A. Harrison, John A. Tomsick +5
We present results from the Nuclear Spectroscopic Telescope Array (NuSTAR) observations of the new black hole X-ray binary candidate MAXI J1631-479 at two epochs during its 2018-20…
Testing the Kerr black hole hypothesis using X-ray reflection spectroscopy and a thin disk model with finite thickness
Askar B. Abdikamalov, Dimitry Ayzenberg, Cosimo Bambi +5
X-ray reflection spectroscopy is a powerful tool for probing the strong gravity region of black holes and can be used for testing general relativity in the strong field regime. Sim…
Plasma-environment effects on K lines of astrophysical interest III. IPs, K thresholds, radiative rates, and Auger widths in Fe ix - Fe xvi
J. Deprince, M. A. Bautista, S. Fritzsche +5
Aims. In the context of black-hole accretion disks, we aim to compute the plasma-environment effects on the atomic parameters used to model the decay of K-vacancy states in moderat…
