Ultraluminous X-ray sources in the first eROSITA survey I. Candidate catalogs
P. Weber, T. P. Roberts, S. Hämmerich +28
Ultraluminous X-ray sources (ULXs) are luminous non-nuclear X-ray point sources embedded in galaxies. Their luminosities exceeding 10^39 erg/s potentially require sub-Eddington acc…
X-ray Reflection as Diagnostic of Supermassive Black Hole Binary Properties
Julie Malewicz, Tamara Bogdanović, David R. Ballantyne +2
We investigate correlations between prominent features in the relativistic X-ray reflection spectrum emitted by an accreting supermassive black hole (SMBH) binary with the underlyi…
Systematic assessment of disk truncation in the black hole X-ray binary Swift J1727.8-1613 using NICER
Ole König, James F. Steiner, Niek Bollemeijer +20
The 2023/24 NICER monitoring campaign of the 7 Crab bright black hole X-ray binary Swift J1727.8-1613 covered the outburst in almost all accretion states. High-quality data are ava…
Constraining black hole spin in PG 1535+547 amidst complex multi-layered absorption
A. Madathil-Pottayil, D. J. Walton, Jiachen Jiang +7
We present a spectroscopic analysis of XMM-Newton and NuSTAR observations of the 'complex' NLS1 PG 1535+547 at redshift . These observations span three epochs: 2002 and 20…
