Non-Thermal Physics Drives Compact, Self-Regulated Galaxy Morphologies at Cosmic Dawn
Michelle S. Park, Sergio Martin-Alvarez, Risa H. Wechsler
James Webb Space Telescope (JWST) has discovered unexpectedly bright, rapidly growing galaxies in the early universe, which were not predicted by most previously existing galaxy fo…
The Azahar Project: Non-Thermal Physics Drives Star Formation Burstiness and the Evolution of the UV Luminosity Density at Cosmic Dawn
Sergio Martin-Alvarez, Risa H. Wechsler, Debora Sijacki
JWST observations, which have pushed the discovery and characterization of galaxies to cosmic dawn, have revealed significant deficiencies in state-of-the-art galaxy formation simu…
The DESI Y1 RR Lyrae catalog I: Empirical modeling of the cyclic variation of spectroscopic properties and a chemodynamical analysis of the outer halo
Gustavo E. Medina, Ting S. Li, Sergey E. Koposov +44
We present the catalog of RR Lyrae stars (RRLs) observed in the first year of operations of the Dark Energy Spectroscopic Instrument (DESI) survey. This catalog contains 6,240 RRLs…
Warm, not Fuzzy: Generalized Ultralight Dark Matter Limits from Milky Way Satellites
Ethan O. Nadler, Mustafa A. Amin, Risa H. Wechsler +3
We generalize lower limits on the dark matter (DM) particle mass derived from Milky Way (MW) satellite galaxy abundances to scenarios in which DM is an ultralight scalar field…
Symfind: Addressing the Fragility of Subhalo Finders and Revealing the Durability of Subhalos
Philip Mansfield, Elise Darragh-Ford, Yunchong Wang +2
A major question in CDM is what this theory actually predicts for the properties of subhalo populations. Subhalos are difficult to simulate and to find within simulations, and…
Exploring gas thermodynamics around galaxies from the Sunyaev-Zel'dovich effects: impact of galaxy-halo connection, 2D projection and velocity field
Sadaf Kadir, Bernardita Ried Guachalla, Sihan Yuan +2
A complete picture of the gas thermodynamics around galaxies is imprinted on the cosmic microwave background (CMB). Indeed, the thermal, kinematic, and relativistic Sunyaev-Zel'dov…
