Genuine Retrieval of the AGN Host Stellar Population (GRAHSP)
Johannes Buchner, Hattie Starck, Mara Salvato +11
The assembly and co-evolution of supermassive black holes (SMBH) and their host galaxy stellar population is a key open questions in galaxy evolution. Stellar mass () and…
COSMOS Spectroscopic Redshift Compilation (First Data Release): 488k Redshifts Encompassing Two Decades of Spectroscopy
Ali Ahmad Khostovan, Jeyhan S. Kartaltepe, Mara Salvato +54
We present the COSMOS Spectroscopic Redshift Compilation encompassing ~ 20 years of spectroscopic redshifts within a 10 deg area centered on the 2 deg COSMOS legacy field.…
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…
Searching for supermassive black holes binaries within SRG/eROSITA-De I: Properties of the X-ray selected candidates
D. TubÃn-Arenas, M. Krumpe, D. Homan +20
Abridged: Supermassive black hole binaries (SMBHBs) separated by (sub)-pc scales represent one of the latest stages of hierarchical galaxy assembly. However, many of these objects…
Systematic Bias in Ionizing Radiation Escape Fraction Measurements from Foreground Large-Scale Structures
C. Scarlata, W. Hu, M. J. Hayes +8
We investigate the relationship between the Lyman-alpha (Lya) forest transmission in the intergalactic medium (IGM) and the environmental density of galaxies, focusing on its impli…
