Sleeping or Dead? Probing the Quenching Mechanism of JWST Dormant Galaxies at z > 3 with ALMA

Mengyuan Xiao, Songnan Qi, Pascal A. Oesch +16

JWST has revealed a population of "dormant'' galaxies at z>3 with strong Balmer breaks and weak emission lines, whose star formation appears to have declined only recently. Whether…

A Census of the 200 Most Massive Galaxies Spectroscopically Observed with JWST at zspec 3-15

Mengyuan Xiao, Pascal A. Oesch, Longji Bing +26

Massive galaxies provide strong tests of galaxy formation models, yet a comprehensive spectroscopic view of their properties and demographics in the early Universe has remained elu…

The quasi-star model for Little Red Dots: potential and challenges

Fabrizio Gentile, Mauro Giavalisco, Emanuele Daddi +25

(Abridged) Little Red Dots (LRDs) are a class of sources discovered by JWST observationally defined by a "V-shaped" rest-frame UV-Optical SED, a compact or unresolved morphology, a…

Euclid: Disky titans - surprisingly high star formation activity and gas content in two brightest group galaxies at z~0.75

F. Gentile, E. Daddi, D. Elbaz +166

We present the discovery of two disky titans in the first data release of the Euclid satellite. These sources are massive (M>10^11 Msun) star-forming (SFR~20 Msun/yr) discs located…

Quiescent fractions in high-redshift galaxy groups reflect their hot-or-cold state of gas accretion

Guillaume Elias, Emanuele Daddi, Chiara D'Eugenio +15

Cold accretion and quenching are closely related aspects of galaxy evolution, as sustained gas supply is required to maintain star formation. High-redshift galaxy groups therefore…

Do little red dots really form a distinct class of astronomical objects?

Jean-Baptiste Billand, David Elbaz, Maximilien Franco +8

JWST observations have identified a class of enigmatic sources known as little red dots (LRDs), interpreted as a distinct class of active galactic nuclei (AGNs) and host galaxies,…
