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…
The giant outburst of EXO 2030+375 II: Broadband spectroscopy and evolution
R. Ballhausen, P. Thalhammer, P. Pradhan +13
In 2021, the high-mass X-ray binary EXO 2030+375 underwent a giant X-ray outburst, the first since 2006, that reached a peak flux of (3-50\,keV). The go…
The giant outburst of EXO 2030+375 I: Spectral and pulse profile evolution
P. Thalhammer, R. Ballhausen, E. Sokolova-Lapa +12
The Be X-ray binary EXO 2030+375 went through its third recorded giant outburst from June 2021 to early 2022. We present the results of both spectral and timing analysis based on N…
Long term variability of Cygnus X-1. VIII. A spectral-timing look at low energies with NICER
Ole König, Guglielmo Mastroserio, Thomas Dauser +19
The Neutron Star Interior Composition Explorer (NICER) monitoring campaign of Cyg X-1 allows us to study its spectral-timing behavior at energies keV across all states. The…
An in-depth analysis of the variable cyclotron lines in GX 3012
Nicolas Zalot, Ekaterina Sokolova-Lapa, Jakob Stierhof +13
Context. The High-Mass X-ray Binary (HMXB) system GX 3012 is a persistent source with a well-known variable cyclotron line centered at 35 keV. Recently, a second cyclotron line…
