COSMOS-Web: The Overabundance and Physical Nature of “Little Red Dots”—Implications for Early Galaxy and SMBH Assembly

JWST has revealed a population of compact and extremely red galaxies at z  ≳ 4, which likely host active galactic nuclei (AGNs). We present a sample of 434 “little red dots” (LRDs), selected from the 0.54 deg ^2 COSMOS-Web survey. We fit galaxy and AGN spectral energy distribution models to derive r...
