The eROSITA Final Equatorial Depth Survey (eFEDS): Complex absorption and soft excesses in hard X-ray--selected active galactic nuclei
Sophia G. H. Waddell, Kirpal Nandra, Johannes Buchner +14
Context. The soft excess, a surplus of X-ray photons above 2 keV with respect to a power law, is a feature of debated physical origin found in the X-ray spectra of many type-1 acti…
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)…
The eROSITA extragalactic CalPV serendipitous catalog
Teng Liu, Andrea Merloni, Julien Wolf +21
The eROSITA X-ray telescope on board the Spectrum-Roentgen-Gamma (SRG) observatory performed calibration and performance verification (CalPV) observations between September 2019 an…
The eROSITA Final Equatorial-Depth Survey (eFEDS): The variability catalogue and multi-epoch comparison
Th. Boller, J. H. M. M. Schmitt, J. Buchner +10
The 140 square degree Final Equatorial-Depth Survey (eFEDS) field, observed with the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) aboard the Spectrum-Roentgen…
The eROSITA Final Equatorial-Depth Survey (eFEDS): The AGN Catalogue and its X-ray Spectral Properties
Teng Liu, Johannes Buchner, Kirpal Nandra +23
Context: After the successful launch of the Spectrum-Roentgen-Gamma (SRG) mission in July 2019, eROSITA, the soft X-ray instrument aboard SRG, performed scanning observations of a…
Systematic evaluation of variability detection methods for eROSITA
Johannes Buchner, Thomas Boller, David Bogensberger +5
The reliability of detecting source variability in sparsely and irregularly sampled X-ray light curves is investigated. This is motivated by the unprecedented survey capabilities o…
