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…
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). These have been interpreted as a distinct class of active galactic nuclei (AGN) an…
The stellar mass function of quiescent and star-forming galaxies and its dependence on morphology in COSMOS-Web
Marko Shuntov, Olivier Ilbert, Claudia del P. Lagos +33
We study the stellar mass function (SMF) of quiescent and star-forming galaxies and its dependence on morphology in 10 redshift bins at using the COSMOS2025 catalog bui…
Dust-UV offsets in high-redshift galaxies in the Cosmic Dawn III simulation
Pierre Ocvirk, Joseph S. W. Lewis, Luke Conaboy +13
Recent observations have revealed puzzling spatial disparities between ALMA dust continuum and UV emission as seen by HST and JWST in galaxies at (e.g. ALPINE and REBELS su…
Clumpiness of galaxies revealed in the near-infrared with COSMOS-Web
Wilfried Mercier, Boris Sindhu Kalita, Marko Shuntov +30
Clumps in the rest-frame UV emission of galaxies have been observed for decades. Since the launch of the James Webb Space Telescope (JWST), a large population is detected in the re…
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…
