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…

Flux variability of the "10 keV feature" of 4U 0115+63

Katrin Berger, Ekaterina Sokolova-Lapa, Ralf Ballhausen +14

X-ray spectra of accretion-powered X-ray pulsars can often be described using a power-law continuum with a high-energy cutoff, which might be further modified by additional spectra…

Unprecedentedly bright X-ray flaring in Cygnus X-1 observed by INTEGRAL

P. Thalhammer, T. Bouchet, J. Rodriguez +15

We study three extraordinarily bright X-ray flares originating from Cyg X-1 seen on 2023 July 10 detected with INTEGRAL. The flares had a duration on the order of only ten minutes…

Multiwavelength study of 1eRASS J085039.9-421151 with eROSITA NuSTAR and X-shooter

Aafia Zainab, Artur Avakyan, Victor Doroshenko +23

The eROSITA instrument on board Spectrum-Roentgen-Gamma has completed four scans of the X-ray sky, leading to the detection of almost one million X-ray sources in eRASS1 only, incl…

Sharp Periodic Flares and Long-Term Variability in the High-Mass X-ray Binary XTE J1829-098 from RXTE PCA, Swift BAT and MAXI Observations

Robin H. D. Corbet, Ralf Ballhausen, Peter A. Becker +20

XTE J1829-098 is a transient X-ray pulsar with a period of ~7.8 s. It is a candidate Be star system, although the evidence for this is not yet definitive. We investigated the twent…

A NuSTAR Census of the X-ray Binary Population of the M31 Disk

Hannah Moon, Daniel R. Wik, V. Antoniou +11

Using hard (E>10 keV) X-ray observations with NuSTAR, we are able to differentiate between accretion states, and thus compact object types, of neutron stars and black holes in X-ra…
