PublicationThe Einstein Ring GAL-CLUS-022058s: a Lensed Ultrabright Submillimeter Galaxy at z = 1.4796
We report an ultrabright lensed submillimeter galaxy at z spec = 1.4796, identified as a result of a full-sky cross-correlation of the AllWISE and Planck...

TalkThe evolution of galaxies during the first billion years.
Evolution of galaxies is relatively well known up to z ~ 5, but beyond this limit and regarding the few number of galaxies confirmed by spectroscopy, their...

PublicationThe Evolving Interstellar Medium of Star-forming Galaxies, as Traced by Stardust
We analyze the far-infrared (FIR) properties of ~5000 star-forming galaxies at z < 4.5, drawn from the deepest, super-deblended catalogs in the GOODS-N and...

PublicationThe GADOT Galaxy Survey: Dense Gas and Feedback in Herschel-selected Starburst Galaxies at Redshifts 2 to 6
We report the detection of 23 OH + 1 → 0 absorption, emission, or P-Cygni-shaped lines and CO(J = 9→8) emission lines in 18 Herschel-selected z = 2-6 starburst...

TalkThe Hunting of relic galaxies in the Nearby Universe
As early as 10 Gyr ago, galaxies with more than 10^11 M* in stars already existed. While most of these massive galaxies must have subsequently transformed...

TalkThe interplay between local and global properties in galaxies
We summarize here some of the results reviewed recently by Sanchez (2020) and Sanchez et al. (2021), comprising the advances in the comprehension of galaxies in...
