Unveil the nature of JWST-AGN and Little Red Dots with SKAO continuum surveys
Giovanni Mazzolari, Dharam V. Lal, Isabella Prandoni +6
The advent of JWST has revealed a large population of AGN at , which are dex more abundant than previously expected, including also the enigmatic population of Little…
No evolution in the number density of little red dots from cosmic dawn to cosmic noon
Federica Loiacono, Roberto Gilli, Marco Mignoli +24
We present our search for little red dots (LRDs) in the "J1030 field", a region of the sky around the quasar SDSS J1030+0524, observed by the JWST EIGER program. Over 1…
MIGHTEE-HI: Mass Models and Dark Matter properties
Anastasia A. Ponomareva, P. E. Mancera Piña, A. A. VÄrÄÅteanu +17
Measuring galaxy rotation curves is critical for inferring the properties of dark-matter haloes in the Lambda Cold Dark Matter (CDM) paradigm. We present HI rotation curves and…
Radio selection of heavily obscured AGN in the J1030 field: unraveling a missing Compton-thick population
Giovanni Mazzolari, Roberto Gilli, Marco Mignoli +21
We tested the effectiveness of radio selection to discover heavily obscured AGNs, particularly at high-z, and we measured their abundance for the first time from a radio perspectiv…
Atomic hydrogen reservoirs in quiescent galaxies at z = 0.4
A. Bianchetti, G. Rodighiero, D. Donevski +11
Context. Based on Local Universe observations, quiescent galaxies (QGs) host lower to no HI compared to star-forming galaxies (SFGs), but no constraints have been derived so far at…
Tracing AGN-Galaxy Co-Evolution with UV Line-Selected Obscured AGN
Luigi Barchiesi, Lucia Marchetti, Mattia Vaccari +11
Understanding black hole-galaxy co-evolution and the role of AGN feedback requires complete AGN samples, including heavily obscured systems. In this work, we present the first UV l…
