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 eROSITA telescope array on board the Spektrum-Roentgen-Gamma (SRG) mission began its all-sky survey program in December 2019, scanning the sky at an approximately six-month cad…

The ASKAP-FLASH survey: A first look at the multiwavelength properties and redshift distribution of compact radio sources

W. Roster, E. M. Sadler, E. K. Mahony +15

We present the characterisation, including a photometric redshift (photo-) analysis, of the optical counterparts (CTPs) to over 45 000 bright ( 30 mJy) comp…

A large population of over-massive black hole quasars at z=0.3-0.8 revealed by eROSITA

Johannes Buchner, Isabelle Gauger, Qiaoya Wu +14

In most galaxies, the central black hole accounts for no more than a percent of the total mass in stars. Recently, however, extremely over-massive black holes with ratios of 10% ha…

Counterpart identification and classification for eRASS1 and characterisation of the AGN content

M. Salvato, J. Wolf, T. Dwelly +44

[abridged] Accurately accounting for the AGN phase in galaxy evolution requires a large, clean AGN sample. This is now possible with SRG/eROSITA. The public Data Release 1 (DR1, Ja…

CircleZ: Reliable Photometric redshifts for AGN computed using only photometry from Legacy Survey Imaging for DESI

A. Saxena, M. Salvato, W. Roster +25

(abridged)Photometric redshifts for AGN (galaxies hosting an accreting supermassive black hole in their center) are notoriously challenging and currently better computed via SED fi…

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…

The SRG/eROSITA all-sky survey -- Identifying the coronal content with HamStar

S. Freund, S. Czesla, P. Predehl +6

The first eROSITA all-sky survey (eRASS1) performed on board the Spectrum-Roentgen-Gamma mission (SRG) provides more than 900,000 X-ray sources in the 0.2 - 2.3 keV band located in…

Characterisation of the X-ray point source variability in the eROSITA south ecliptic pole field

David Bogensberger, Kirpal Nandra, Mara Salvato +11

Aims: During the Spectrum Roentgen Gamma (SRG)/ eROSITA all-sky surveys, X-ray sources close to the South Ecliptic Pole (SEP) are observed almost every 4 hours. We aim to identify…

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…
