A pilot sample of Planck-selected strongly lensed sub-mm galaxies: NOEMA observations and physical characterisation

Leonardo Trobbiani, Matteo Bonato, Ivano Baronchelli +6

The extreme brightness of high- strongly lensed galaxies detected by Planck surveys, thanks to their exceptionally large gravitational magnifications, offers a unique opportunit…

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…

Beyond the Dot: an LRD-like nucleus at the Heart of an IR-Bright Galaxy and its implications for high-redshift LRDs

Pierluigi Rinaldi, George H. Rieke, Zihao Wu +23

Little Red Dots (LRDs) are compact, red sources discovered by JWST at high redshift (), marked by distinctive 'V-shaped' spectral energy distributions (SEDs) and often…

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…

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…
