X-ray emission from a rapidly accreting narrow-line Seyfert 1 galaxy at z=6.56
Julien Wolf, Kirpal Nandra, Mara Salvato +14
This study aims at identifying luminous quasars at among X-ray-selected sources in the eROSITA Final Equatorial-Depth Survey (eFEDS) in order to place a lower limit on blac…
The first look at Narrow-Line Seyfert 1 Galaxies with eROSITA
G. Grünwald, Th. Boller, S. Rakshit +6
We present the first look at the spectral and timing analysis of Narrow-Line Seyfert 1 Galaxies (NLS1s) with the extended ROentgen Survey with an Imaging Telescope Array (eROSITA)…
AGN sub-populations important for black hole mass growth: a rule of thumb
Johannes Buchner
For building the super-massive black hole population within a Hubble time, only sub-populations with more than 10^52 erg/s / L objects on the sky are relevant, where L is the sampl…
Deciphering the extreme X-ray variability of the nuclear transient eRASSt J045650.3-203750: A likely repeating partial tidal disruption event
Zhu Liu, A. Malyali, M. Krumpe +17
(Abridged) In this paper, we present the results of an exceptional repeating X-ray nuclear transient, eRASSt J045650.3-203750 (hereafter J0456-20), uncovered by SRG/eROSITA in a qu…
Localizing narrow Fe K emission within bright AGN
Carolina Andonie, Franz E. Bauer, Rosamaria Carraro +11
The 6.4 keV Fe Ka emission line is a ubiquitous feature in X-ray spectra of AGN, and its properties track the interaction between the variable primary X-ray continuum and the surro…
The complex time and energy evolution of quasi-periodic eruptions in eRO-QPE1
R. Arcodia, G. Miniutti, G. Ponti +8
Quasi-periodic eruptions (QPEs) are recurrent X-ray bursts found so far in the nuclei of low-mass galaxies. Their trigger mechanism is still unknown, but recent models involving on…
