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…

Little Red Dots on FIRE: Exploring the formation and observational signatures of ultra-compact early galaxies

Niranjan Chandra Roy, Daniel Anglés-Alcázar, Rachel K. Cochrane +15

Little Red Dots (LRDs) are compact sources with broad Balmer lines, Balmer breaks, anomalous UV emission, rising red continuum, and uncertain origin. We use FIRE cosmological simul…

The Lifecycle and Emission Properties of PAHs in Cosmological Hydrodynamic Galaxy Formation Simulations

Desika Narayanan, Paul Torrey, Massimiliano Parente +16

We present the first cosmological model for the lifecycle and luminous properties of PAHs in galaxies as they evolve from z=6-->0. We model 40 zoom-in galaxies, coupled with an on-…

Dust in the Average Galaxy: Attenuation, Emission, and Opacity from

Caitlin M. Casey, Hollis B. Akins, Andrew J. Battisti +43

We present constraints on the dust emission and attenuation properties of galaxies across 0<z<7 using JWST imaging from the COSMOS-Web Survey combined with deep FIR/(sub)millimeter…

COSMOS-Web galaxy groups: Evolution of red sequence and quiescent galaxy fraction

Greta Toni, Matteo Maturi, Gianluca Castignani +33

We investigate the redshift and group richness dependence of the quiescent fraction and red-sequence (RS) parameters in COSMOS galaxy groups from z=0 to z=3.7. We analyzed the deep…

Summary of Discussion Sessions from "The Dusty Universe 2025: The Fifth Pandust Conference"

Marjorie Decleir, Karl D. Gordon, Annalisa De Cia +16

"The Dusty Universe: The Fifth Pandust Conference" took place in Tucson (AZ, USA) from November 10 until 14, 2025. The goal of this meeting was to get the dust community together t…
