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…
AGN radiative feedback as the main regulator of [O III] outflow activity and obscuration in X-ray AGN
Carolina Andonie, Andrea Merloni, Catarina Aydar +12
Large-scale ionised outflows and nuclear obscuration are fundamental manifestations of AGN activity, yet direct observational evidence linking these phenomena remains scarce. We us…
SDSS-V: Revealing a weak accretion state in X-ray selected red quasars
Paloma Guetzoyan, James Aird, Amy L. Rankine +17
Red quasars (rQSOs) have been recognized as a short-lived, early stage in the evolutionary cycle of Active Galactic Nuclei (AGN), with fundamental differences in their intrinsic pr…
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…
Discovery of an X-ray Luminous Radio-Loud Quasar at : A Possible Transitional Super-Eddington Phase
Sakiko Obuchi, Kohei Ichikawa, Satoshi Yamada +11
We report the multiwavelength properties of eFEDS J084222.9+001000 (hereafter ID830), a quasar at , identified as the most X-ray luminous radio-loud quasar in the eROSITA…
X-ray selected broad absorption line quasars in SDSS-V: BALs and non-BALs span the same range of X-ray properties
Pranavi Hiremath, Amy L. Rankine, James Aird +10
Broad absorption line (BAL) quasars are often considered X-ray weak relative to their optical/UV luminosity, whether intrinsically (i.e., the coronal emission is fainter) or due to…
The global energetics of radio AGN kinetic feedback in the local universe
Zsofi Igo, Andrea Merloni
[abridged] AGN feedback is a crucial ingredient for understanding galaxy evolution. However, a complete quantitative time-dependent framework, including the dependence of such feed…
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…
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…
