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…
Measuring black hole spins with x-ray reflection spectroscopy: A GRMHD outlook
Swarnim Shashank, Askar B. Abdikamalov, Honghui Liu +4
X-ray reflection spectroscopy has evolved as one of the leading methods to measure black hole spins. However, the question is whether its measurements are subjected to systematic b…
Physics of Strong Magnetism with eXTP
Mingyu Ge, Long Ji, Roberto Taverna +47
In this paper we present the science potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission, in its new configuration, for studies of strongly magnetized compact obj…
