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…

The Critical Mass in Galaxy Evolution

Preetish K. Mishra, Changbom Park, Jaehyun Lee +4

We investigate the physical origin of critical mass, a threshold where many galaxy properties and scaling relations undergo fundamental transitions, using the Horizon Run 5 simulat…

Double-Peaked Ly Emission during Reionization Requires Nearby Voids and a Favorable Local Ionizing Background

Hyunbae Park, Aaron Smith, Intae Jung +11

Several Lyman-alpha (Ly) emitters deep into the reionization era exhibit double-peaked Ly emission profiles, raising the question of how the intergalactic medium can transm…

CALIMA: On-the-fly dust and PAH evolution for radiation-hydrodynamics galaxy formation simulations

Francisco Rodríguez Montero, Yohan Dubois, Harley Katz +2

Dust grains and polycyclic aromatic hydrocarbons (PAHs) actively contribute to the thermodynamics, chemistry, and radiative state of the interstellar medium (ISM), yet most ISM mod…

RAMSES-MCR: A consistent multi-group treatment of cosmic rays physics in momentum-space with the RAMSES code

Nimatou-Seydi Diallo, Yohan Dubois, Alexandre Marcowith +2

Cosmic rays (CRs) are known to play a key role in many astrophysical environments: they can modify shock dynamics, influence the thermochemistry and the ionization of the interstel…

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…
