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…
DustPedia and Local Volume Legacy samples as benchmarks for dust evolution in galaxies
Evangelos D. Paspaliaris, Simone Bianchi, Edvige Corbelli +8
DustPedia and LVL are two samples representative of the local galaxy population, including in total 1011 unique objects of all morphological types, with a wide range of stellar mas…
JWST spectroscopic confirmation of the Cosmic Gems arc at z=9.625 -- Insights into the small scale structure of a post-burst system
M. Messa, E. Vanzella, F. Loiacono +30
We present JWST/NIRSpec integral field spectroscopy of the Cosmic Gems arc, strongly magnified by the galaxy cluster SPT-CL J06155746. Six-hour integration using NIRSpec prism s…
A big red dot at cosmic noon
Federica Loiacono, Roberto Gilli, Marco Mignoli +22
We report the discovery of a little red dot (LRD), dubbed BiRD ('big red dot'), at in the field around the quasar SDSSJ1030+0524. Using NIRCam images, we identifie…
Need for PRIMA to understand the nature and ISM physical conditions of HST-dark galaxies
Carlotta Gruppioni, Lee Armus, Matthieu Bethermin +10
One of the main open issues in galaxy formation and evolution is the early assembly of the most massive galaxies and their contribution to the stellar mass and star formation rate…
The PRIMA promise of deciphering interstellar dust evolution with observations of the nearby Universe
Frédéric Galliano, Maarten Baes, Léo Belloir +25
This paper develops a few science cases, using the PRIMA far-IR probe, aimed at achieving several breakthroughs in our understanding of the dust properties and their evolution. We…
