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…
The SRG/eROSITA all-sky survey: First X-ray catalogues and data release of the western Galactic hemisphere
A. Merloni, G. Lamer, T. Liu +142
The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite began surveying the sky in December 2019, with the aim of producing all-sky X-ray source lists and sk…
Variability as a predictor for the hard-to-soft state transition in GX 339-4
Matteo Lucchini, Marina Ten Have, Jingyi Wang +17
During the outbursts of black hole X-ray binaries (BHXRBs), their accretion flows transition through several states. The source luminosity rises in the hard state, dominated by non…
Investigating the impact of vertically extended coronae on X-ray reverberation mapping
Matteo Lucchini, Guglielmo Mastroserio, Jingyi Wang +9
Accreting black holes commonly exhibit hard X-ray emission, originating from a region of hot plasma near the central engine referred to as the corona. The origin and geometry of th…
The spectral-timing analysis of Cygnus X-1 with Insight-HXMT
M. Zhou, V. Grinberg, Q. -C. Bu +12
Cygnus X-1, as the first discovered black hole binary, is a key source for understanding the mechanisms of state transitions, and the scenarios of accretion in extreme gravity fiel…
Broadband study and the discovery of pulsations from the Be/X-ray binary eRASSU J052914.9-662446 in the Large Magellanic Cloud
C. Maitra, D. Kaltenbrunner, F. Haberl +12
Context. The Magellanic Clouds are our nearest star-forming galaxies. While the population of high-mass X-ray binaries (HMXBs) in the Small Magellanic Cloud (SMC) is relatively wel…
Detecting clusters of galaxies and active galactic nuclei in an eROSITA all-sky survey digital twin
R. Seppi, J. Comparat, E. Bulbul +15
The extended ROentgen Survey with an Imaging Telescope Array (eROSITA) onboard the Spectrum-Roentgen-Gamma (SRG) observatory is revolutionizing X-ray astronomy. It provides large s…
On measuring the Hubble constant with X-ray reverberation mapping of active galactic nuclei
Adam Ingram, Guglielmo Mastroserio, Michiel van der Klis +8
We show that X-ray reverberation mapping can be used to measure the distance to type 1 active galactic nuclei (AGNs). This is because X-ray photons originally emitted from the `cor…
Identification of SRGt 062340.2-265715 as a bright, strongly variable, novalike cataclysmic variable
Axel Schwope, David A. H. Buckley, Adela Kawka +10
We report the identification and follow-up of the transient SRG 062340.2-265715 detected with both instruments on board the Spektrum-Roentgen-Gamma mission. Optical spectroscopy of…
