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…

Memoirs of mass accretion: probing the edges of intracluster light in simulated galaxy clusters

Tara Dacunha, Phil Mansfield, Risa Wechsler

The diffuse starlight extending throughout massive galaxy clusters, known as intracluster light (ICL), has the potential to be read as a memoir of mass accretion: informative, indi…

The Pandora project. II: how non-thermal physics drives bursty star formation and temperate mass-loaded outflows in dwarf galaxies

Sergio Martin-Alvarez, Debora Sijacki, Martin G. Haehnelt +11

Dwarf galaxies provide powerful laboratories for studying galaxy formation physics. Their early assembly, shallow gravitational potentials, and bursty, clustered star formation his…

Shaping the Milky Way. II. The dark matter halo's response to the LMC's passage in a cosmological context

Elise Darragh-Ford, Nicolas Garavito-Camargo, Arpit Arora +15

The distribution of dark matter in the Milky Way (MW) is expected to exhibit a large-scale dynamical response to the recent infall of the LMC. This event produces a dynamical frict…
