Galaxy formation is at the heart of our understanding of cosmic evolution. Although there is a
consensus that galaxies emerged from the expanding matter background by gravitational …

The observable characteristics and subsequent evolution of young stellar populations is
dominated by their massive stars. As our understanding of those massive stars and the …

We present emission-line measurements and physical interpretations for a sample of 117 [O
iii] emitting galaxies at z= 5.33–6.93, using the first deep JWST/NIRCam wide-field slitless …

In the ΛCDM paradigm, the Galactic stellar halo is predicted to harbor the accreted debris of
smaller systems. To identify these systems, the H3 Spectroscopic Survey, combined with …

The ultraviolet (UV) continuum slope (β, where f λ∝ λ β) of galaxies is sensitive to a variety
of properties, from the metallicity and age of the stellar population to dust attenuation …

ABSTRACT The Feedback In Realistic Environments (FIRE) project explores feedback in
cosmological galaxy formation simulations. Previous FIRE simulations used an identical …

The Binary Population and Spectral Synthesis suite of binary stellar evolution models and
synthetic stellar populations provides a framework for the physically motivated analysis of …

We measure escape fractions, f esc, of ionizing radiation from galaxies in the sphinx suite of
cosmological radiation-hydrodynamical simulations of reionization, resolving haloes with …

The protagonists of the last great phase transition of the universe—cosmic reionization—
remain elusive. Faint star-forming galaxies are leading candidates because they are found …

The ionizing photon escape fraction [Lyman continuum (LyC) f esc] of star-forming galaxies
is the single greatest unknown in the reionization budget. Stochastic sightline effects prohibit …
