Steep-spectrum AGN in eROSITA Final Equatorial-Depth Survey (eFEDS): Their host galaxies and multi-wavelength properties
K. Iwasawa, T. Liu, Th. Boller +12
We selected sources with a steep soft-X-ray-band spectrum with a photon index larger than 2.5 -- measured by eROSITA on board the Spectrum-Roentgen-Gamma (SRG) -- from the eFEDS AG…
The SRG/eROSITA all-sky survey: Hard X-ray selected Active Galactic Nuclei
Sophia G. H. Waddell, J. Buchner, K. Nandra +12
The eROSITA instrument aboard the Spectrum Roentgen Gamma (SRG) satellite has performed its first all-sky survey between December 2019 and June 2020. This paper presents the result…
The eROSITA Final Equatorial Depth Survey (eFEDS): the hard X-ray selected sample
K. Nandra, S. G. H. Waddell, T. Liu +25
During its calibration and performance verification phase, the eROSITA instrument aboard the SRG satellite performed a uniform wide--area X-ray survey of approximately 140 deg$^{2}…
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…
Ensemble X-ray variability of optically selected QSOs: dependence on black hole mass and Eddington ratio
A. Georgakakis, J. Buchner, A. Ruiz +7
Although flux variability is one of the defining properties of accretion flows onto supermassive black holes, its dependence on physical parameters such as the mass of the compact…
The eROSITA DR1 variability catalogue
Th. Boller, M. Salvato, J. Buchner +14
With its first All-Sky Survey (eRASS1), the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) on board the Spectrum-Roentgen-Gamma (SRG) mission has offered an unp…
