COSMOS-Web: From early star-formation enhancement to late suppression in galaxy groups
R. C. Arango-Toro, C. Laigle, J. Lewis +27
Galaxy groups trace dense environments where interactions, gas removal, and reduced accretion may drive quenching. Common diagnostics trace star formation over short timescales ($\…

COSMOS-Web: does halo mass alone shape the clustering of star-forming and quiescent galaxies?
Louise Paquereau, Clotilde Laigle, Henry Joy McCracken +29
While stellar mass correlates strongly with halo mass, it remains unclear whether halo mass alone governs galaxy star-formation activity, or whether secondary halo properties and e…

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…
