Resolved Dust in Galaxies with JWST/MIRI MRS: Survey Description and First View on PAHs, Mid-IR Atomic Emission, and Warm H
Wuji Wang, Andreas L. Faisst, Thomas S. -Y. Lai +16
Dust is a key component of galaxies that regulates their thermal balance and, consequently, star formation and the build-up of stellar mass. Polycyclic aromatic hydrocarbons (PAHs)…
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
