The SRG/eROSITA All-Sky Survey DR2: Cumulative X-ray catalogues from the first three surveys and multi-wavelength counterparts in the western Galactic hemisphere
M. E. Ramos-Ceja, G. Lamer, M. Salvato +111
The paper presents the second data release of the SRG/eROSITA all‑sky survey, providing catalogues of nearly two million X‑ray sources (point‑like and extended) from the first thre…
Strong X-ray Variability of I Zwicky 1: Obscuration from Clumpy Accretion-Disk Winds
Jian Huang, Bin Luo, W. N. Brandt +2
Obscuration from clumpy accretion-disk winds has been invoked to explain the extreme X-ray weakness and X-ray variability observed in a substantial fraction of super-Eddington accr…
Investigating central star formation in local AGN host galaxies: is there tension between coeval growth and AGN feedback?
Q. Ni, K. Nandra, A. Merloni +3
It has been argued that supermassive black holes (BHs) coevolve with the central parts of galaxies, as a result of the common fuel for both the BH and star formation in the galaxy…
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…
The eROSITA Final Equatorial Depth Survey (eFEDS): SDSS spectroscopic observations of X-ray sources
Catarina Aydar, Andrea Merloni, Tom Dwelly +45
We present one of the largest uniform optical spectroscopic surveys of X-ray selected sources to date that were observed as a pilot study for the Black Hole Mapper (BHM) survey. Th…
