The incidence of eROSITA X-ray AGN in the local Universe: from dwarf to massive galaxies
Z. Igo, A. Merloni, A. Georgakakis +22
Combining deep, wide-area X-ray surveys with multi-wavelength catalogues provides insights into rare, highly-accreting AGN and low-mass galaxies at low redshift, the latter potenti…
Spatially resolved optical and mid-infrared spectroscopy of SDSS1335+0728: implications for the origin of the Ansky event
P. Sánchez-Sáez, M. Masterson, L. Hernández-García +25
The galaxy SDSS1335+0728 brightened abruptly in December 2019 (the Ansky event) and has since been confirmed as the host of extreme X-ray quasi-periodic eruptions (QPEs) of debated…
The SRG/eROSITA All-Sky Survey: X-ray beacons at late cosmic dawn
J. Wolf, M. Salvato, S. Belladitta +12
The SRG/eROSITA All-Sky Survey (eRASS) is expected to contain ~100 quasars that emitted their light when the universe was less than a billion years old, i.e. at z>5.6. By selection…
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…
Massive black holes in nuclear star clusters: Investigation with SRG/eROSITA X-ray data
Nils Hoyer, Riccardo Arcodia, Silvia Bonoli +4
Massive black holes (MBHs) are typically hosted in the centres of massive galaxies but they appear to become rarer in lower mass galaxies, where nuclear star clusters (NSCs) freque…
O Corona, where art thou? eROSITA's view of UV-optical-IR variability-selected massive black holes in low-mass galaxies
R. Arcodia, A. Merloni, J. Comparat +16
Finding massive black holes (MBHs, ) in the nuclei of low-mass galaxies () is crucial to constrain seeding and…
A new discovery space opened by eROSITA: Ionised AGN outflows from X-ray selected samples
Blessing Musiimenta, Marcella Brusa, Teng Liu +21
In the context of an evolutionary model, the outflow phase of an Active Galactic Nuclei (AGN) occurs at the peak of its activity, once the central SMBH is massive enough to generat…
The eROSITA Final Equatorial-Depth Survey (eFEDS): Host-galaxy Demographics of X-ray AGNs with Subaru Hyper Suprime-Cam
Junyao Li, John D. Silverman, Andrea Merloni +12
We investigate the physical properties, such as star-forming activity, disk vs. bulge nature, galaxy size, and obscuration of 3796 X-ray selected AGNs at in the eFEDS f…
The eROSITA Final Equatorial-Depth Survey (eFEDS): A multiwavelength view of WISE mid-infrared galaxies/active galactic nuclei
Yoshiki Toba, Teng Liu, Tanya Urrutia +21
We investigate the physical properties--such as the stellar mass, SFR, IR luminosity, X-ray luminosity, and hydrogen column density--of MIR galaxies and AGN at in the 140 d…
The eROSITA Final Equatorial-Depth Survey (eFEDS): An X-ray bright, extremely luminous infrared galaxy at z = 1.87
Yoshiki Toba, Marcella Brusa, Teng Liu +15
In this study, we investigate the X-ray properties of WISE J090924.01+000211.1 (WISEJ0909+0002), an extremely luminous infrared (IR) galaxy (ELIRG) at = 1.871 in the…
First constraints on the AGN X-ray luminosity function at from an eROSITA-detected quasar
Julien Wolf, Kirpal Nandra, Mara Salvato +19
We searched for high-z quasars within the X-ray source population detected in the contiguous eFEDS field observed by eROSITA during the performance verification phase.…
The final SDSS-IV/SPIDERS X-ray point source spectroscopic catalogue
J. Comparat, A. Merloni, T. Dwelly +15
We look to provide a detailed description of the SPectroscopic IDentification of ERosita Sources (SPIDERS) survey, an SDSS-IV programme aimed at obtaining spectroscopic classificat…
