Probing cold gas and dust in quiescent galaxies across cosmic time

Anita Zanella, Sirio Belli, Belen Alcalde Pampliega +35

The discovery of massive quiescent galaxies at high redshift by JWST has revealed that star formation can cease rapidly in the early Universe, yet the physical mechanisms responsib…

Unveiling the Baryon Cycle Through Cosmic Time

Manuel Aravena, Leindert A. Boogaard, Jorge González-López +28

Galaxy evolution is governed by the baryon cycle: gas accreted from the cosmic web and circumgalactic medium condenses into molecular gas, forms stars, and is redistributed by stel…

The dawn of the first galaxies

Livia Vallini, Tanio Diaz Santos, Belen Alcalde Pampliega +56

Understanding how the first galaxies assembled their stellar mass at cosmic dawn is a central frontier of modern astrophysics. JWST has now revealed an unexpected population of ult…

Testing dark matter models and modified gravity theories with spatially resolved HI observations

Federico Lelli, Antonino Marasco, Timothy A. Davis +8

Understanding the nature of dark matter (DM) is one of the most pressing questions of modern physics. The flat rotation curves of galaxies, especially the extended HI rotation curv…

Probing the molecular gas content of galaxies in an over-dense group at z~0.7: A test case for environmental quenching

Jonathan Freundlich, Benoît Epinat, Thierry Contini +14

We investigated the impact of group environment on molecular gas reservoirs at an intermediate redshift by observing the CO(2-1) emission from the galaxy group COSMOS-Gr30 at $z \s…

Resolved molecular gas and star-formation in massive unquenched spirals : I. UGC 8179

Romane Cologni, Simon Flesch, Philippe Salomé +7

Recent studies have uncovered a rare population of super-massive (M* > 1e11 Msun) star-forming spiral galaxies, Super Spiral Galaxies (SSGs), whose existence challenges classical q…
