DAO: A New and Public Non-Relativistic Reflection Model
Yimin Huang, Honghui Liu, Cosimo Bambi +4
We present a new non-relativistic reflection model, DAO, designed to calculate reflection spectra in the rest frame of accretion disks in X-ray binaries and active galactic nuclei.…
Assessing the Power-Law Emissivity Assumption in X-ray Reflection Spectroscopy: A Simulation-Based Evaluation of Different Coronal Geometries
Songcheng Li, Abdurakhmon Nosirov, Cosimo Bambi +3
The emissivity profile assumed in X-ray reflection spectroscopy significantly impacts black hole spin measurements. Using simulated NuSTAR spectra generated for lamppost and disk-l…
Spin Constraints on 4U 1630-47 via combined Continuum Fitting and Reflection methods: a comparative study using Frequentist and Bayesian statistics
Debtroy Das, Honghui Liu, Zuobin Zhang +5
We present a comprehensive Bayesian spectral analysis of the black hole X-ray binary 4U 1630-47 during its 2022 outburst, using simultaneous NICER and NuSTAR observations. Using th…
X-ray reflection spectroscopy with improved calculations of the emission angle
Yimin Huang, Honghui Liu, Temurbek Mirzaev +10
The reflection spectrum produced by a cold medium illuminated by X-ray photons is not isotropic and its shape depends on the emission angle. In the reflection spectrum of an accret…
Narrow-Line Seyfert 1 Galaxies Beyond the Local X-ray Universe: An X-ray spectral sample
Jiachen Jiang, Dominic J. Walton, Luigi C. Gallo +8
Narrow-line Seyfert 1 AGNs (NLS1s) represent a unique stage in the black hole growth history, characterised by low black hole masses of approximately - solar masses…
Impact of the returning radiation on X-ray reflection spectroscopy measurements: the case of Galactic black holes
Kexin Huang, Honghui Liu, Cosimo Bambi +2
The effect of the returning radiation has long been ignored in the analysis of the reflection spectra of Galactic black holes and active galactic nuclei and only recently has been…
