No luminous Little Red Dots: A sharp cutoff in their luminosity function

One of the most surprising results of early James Webb Space Telescope (JWST) observations is the discovery of an abundance of red, compact, broad-line objects dubbed “little red dots” (LRDs) at z > 4. Their spatial density (∼10−4–10−5 cMpc−3) is 100 times more abundant than UV-selected quasars at t
