A remarkable Ruby: Absorption in dense gas, rather than evolved stars, drives the extreme Balmer break of a Little Red Dot at
Anna de Graaff, Hans-Walter Rix, Rohan P. Naidu +25
The origin of the rest-optical emission of compact, red, high-redshift sources known as `little red dots' (LRDs) poses a major puzzle. If interpreted as starlight, it would imply t…
Gas outflows in two recently quenched galaxies at z = 4 and 7
F. Valentino, K. E. Heintz, G. Brammer +33
Outflows are a key element in the baryon cycle of galaxies, and their properties provide a fundamental test for our models of how star formation quenches in galaxies. Here we repor…
Detection of the 2175Å UV Bump at z>7: Evidence for Rapid Dust Evolution in a Merging Reionisation-Era Galaxy
Katherine Ormerod, Joris Witstok, Renske Smit +15
Dust is a fundamental component of the interstellar medium within galaxies, as dust grains are highly efficient absorbers of ultraviolet (UV) and optical photons. Accurately quanti…
Discovery of Ancient Globular Cluster Candidates in the Relic, a Quiescent Galaxy at
Katherine E. Whitaker, Sam E. Cutler, Rupali Chandar +31
Globular clusters (GCs) are some of the oldest bound structures in the Universe, holding clues to the earliest epochs of star formation and galaxy assembly. However, accurate age m…
