Euclid Quick Data Release (Q1). Searching for radio-selected \Euclid-dark galaxies in the EDF-N
Euclid Collaboration, M. Giulietti, I. Prandoni +308
We present and investigate the properties of a sample of radio-selected, Euclid-dark galaxies, identified from LOFAR HBA observations at 144 MHz within the Euclid Deep Field-North…
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…
Little Red and Blue Dots: AGN-excited narrow lines, Lyman- emission, and resemblance to standard quasars
Sophia Geris, Roberto Maiolino, Xihan Ji +35
We present an analysis of a sample of 36 Little Red and Blue Dots (LRDs and LBDs) at , identified by JWST in the GOODS fields. While both categories are selected to ha…
Strong environmental AGN enhancement among DSFGs in z > 2 protoclusters
Monica Natalia Isla Llave, Fabio Vito, Alberto Traina +17
Galaxy protoclusters (PCs) at z > 2 are dense regions in which cold gas availability and elevated galaxy interaction rates trigger intense, often dust-obscured, star formation. The…
The GlimmIr: Spectroscopic Variability in a z~7 LRD Indicates Rapid Changes in Both the Narrow and Broad Line Regions
Erini Lambrides, Taylor A. Hutchison, Rebecca L. Larson +39
The enigmatic population of ``Little Red Dots'' (LRDs) sit at the center of some of the largest debates in extragalactic astronomy today. The source(s) of ionizing emission and the…
