Beyond Disk Truncation: X-ray Reverberation Signatures of an Outflowing Corona
Ke Qin, Bei You, Adam Ingram +1
The corona in black hole X-ray binaries (BHXRBs) is likely dynamic during outbursts. A mildly relativistic outflowing corona has been proposed to explain hard spectra, weak disk re…
A clean broad iron line in GS 1354--64 as seen by XRISM
Honghui Liu, Lingda Kong, Oluwashina K. Adegoke +13
We present a spectroscopic analysis of XRISM and NuSTAR observations of the black hole X-ray binary GS~1354--64 during its 2026 outburst. A total number of 3.5 million photons are…
Decoding Cygnus X-2: The Critical Role of Reflection in IXPE Data
Honghui Liu, Jiachen Jiang, Adam Ingram +10
We present a spectro-polarimetric re-analysis of the first IXPE observation of Cygnus X-2 which we determine to be mainly in the normal branch, from quasi-simultaneous observations…
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.…
The 2025 Failed Outburst of IGR J17091-3624: Spectral Evolution and the Role of Ionized Absorbers
Oluwashina K. Adegoke, Javier A. Garcia, Guglielmo Mastroserio +15
IGR J17091-3624 is the only black hole X-ray binary candidate, aside from the well-studied black hole system GRS 1915+105, observed to exhibit a wide range of structured variabilit…
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…
Millihertz Oscillations Near the Innermost Orbit of a Supermassive Black Hole
Megan Masterson, Erin Kara, Christos Panagiotou +22
Recent discoveries from time-domain surveys are defying our expectations for how matter accretes onto supermassive black holes (SMBHs). The increased rate of short-timescale, repet…
The Effect of Returning Radiation on Relativistic Reflection
Thomas Dauser, Javier A García, Amy Joyce +5
We study the effect of returning radiation on the shape of the X-ray reflection spectrum in the case of thin accretion disks. We show that the returning radiation mainly influences…
