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…

Tracing the galaxy-halo connection with galaxy clustering in COSMOS-Web from z = 0.1 to z ~ 12

Louise Paquereau, Clotilde Laigle, Henry Joy McCracken +31

We explore the evolving relationship between galaxies and their dark matter halos from to using mass-limited angular clustering measurements in the 0.54 de…

COSMOS-Web: A history of galaxy migrations over the stellar mass-star formation rate plane

R. C. Arango-Toro, O. Ilbert, L. Ciesla +39

The stellar mass-star formation rate (-) plane is a fundamental diagnostic for distinguishing galaxy populations. However, the evolutionary pathways of…

The COSMOS-Web ring: Spectroscopic confirmation of the background source at z = 5.1

Marko Shuntov, Shuowen Jin, Wilfried Mercier +22

We report the spectroscopic confirmation of the background source of the most distant Einstein ring known to date, the COSMOS-Web ring. This system consists of a complete Einstein…

COSMOS-Web: stellar mass assembly in relation to dark matter halos across of cosmic history

M. Shuntov, O. Ilbert, S. Toft +43

We study the stellar mass function (SMF) and the co-evolution with dark matter halos via abundance matching in the largest redshift range to date in $0.53 \, {\rm deg}^2…
