The X-ray weakness of Little Red Dots and JWST-selected AGN: comparison with local AGN in different accretion regimes
A. Tortosa, C. Ricci, P. Du +5
We investigate the origin of the observed X-ray weakness in high z LRDs and other JWST-selected broad line AGN by comparing their X-ray and optical properties with those of a diver…

INSPIRE: INvestigating Stellar Populations In RElics. IX. KiDS J0842+0059: the first fully confirmed relic beyond the local Universe
C. Tortora, G. Tozzi, G. Agapito +20
Relics are massive, compact and quiescent galaxies that assembled the majority of their stars in the early Universe and lived untouched until today, completely missing any subseque…
