A Unified Framework Connecting Chemical Enrichment to Resolved Star Formation Histories with Applications to Local Group Dwarf Irregulars
Christopher T. Garling, Alex M. Garcia, Niusha Ahvazi +4
The paper introduces a framework that combines resolved star formation histories with chemical evolution models to trace the metallicity growth of dwarf galaxies, and applies it to…
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…
Pickles on FIRE: The 3D Shape Evolution of Simulated Milky Way-Mass Galaxies
Luke Y. Xia, Courtney Klein, Jenny D. Wang +6
We use reduced-mass eigentensors to quantify the 3D ellipsoidal shape evolution of thirteen Milky Way-mass galaxies simulated using zoom simulations with FIRE-2 physics; all but on…
Beyond Cloud-9: The case for discovering more HI-rich failed halos
Jorge Moreno, Coral Wheeler, Francisco J. Mercado +8
HI-rich starless halos, should they exist, hold great promise for elucidating dark matter halo structure. Yet realizing this potential demands reliable theoretical predictions for…
Towards Unbreaking the Universe: MINERVA Measurements of Color Gradients in Massive Quiescent Galaxies Can Help Ease Too-Early Star Formation Tensions
Sam E. Cutler, Luke Robbins, Danilo Marchesini +41
The discovery of a population of massive, ancient quiescent galaxies within the first 2 Gyr of the Universe's history has led to significant tensions with models of galaxy formatio…
The Nature of Post-Starburst Galaxies: Real Deal or Masquerading Impostors?
Elia Cenci, Robert Feldmann, Sarah Wellons +7
Post-starburst galaxies (PSBs) are a population of galaxies with spectral and photometric features indicative of rapid quenching following a recent starburst. The origin and nature…
