Tentative Detection of Neutral Gas in a Little Red Dot at z = 4.46

JWST has revealed a population of broad-line active galactic nuclei at z > 4 with remarkably red colors, so-called “Little Red Dots” (LRDs). Ubiquitous Balmer breaks suggest that they harbor old stellar populations in massive, compact host galaxies. We present Atacama Large Millimeter/submillimeter...
