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…
Discovery of two Einstein crosses from massive post--blue nugget galaxies at z>1 in KiDS
N. R. Napolitano, R. Li, C. Spiniello +18
We report the discovery of two Einstein Crosses (ECs) in the footprint of the Kilo-Degree Survey (KiDS): KIDS J232940-340922 and KIDS J122456+005048. Using integral field spectrosc…
New high-quality strong lens candidates with deep learning in the Kilo Degree Survey
R. Li, N. R. Napolitano, C. Tortora +11
We report new high-quality galaxy scale strong lens candidates found in the Kilo Degree Survey data release 4 using Machine Learning. We have developed a new Convolutional Neural N…
