Significant or Not? The Impact of Randomisation During Data Reduction on Confirming a New Pulsating Ultraluminous X-ray Source Candidate in Centaurus A
Amy H. Knight, Timothy P. Roberts, Callum Potter +2
We report the discovery of a new candidate pulsating ultraluminous X-ray source (PULX) in NGC 5128 (Centaurus A). The candidate, 4XMM J132542.2-425943, is a transient source, ident…
Spin Demographics of Active Supermassive Black Holes: Updated Estimates from X-ray reflection and Future opportunities
Julia M. Sisk-Reynes, Christopher S. Reynolds, James H. Matthews +5
Understanding the growth of supermassive black holes (SMBHs) requires observational constraints on how their angular momentum (or spin) varies with mass, since the relative importa…
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…
Normalizing a Relativistic Model of X-ray Reflection: The Definition of the Reflection Fraction and its Implementation in relxill
T. Dauser, J. Garcia, D. J. Walton +4
The only relativistic reflection model that implements a parameter relating the intensity incident on an accretion disk to the observed intensity is relxill. The parameter used in…
