James Webb’s Little Red Dots

Abstract: One of the first discoveries by the James Webb Space Telescope were the bright and compact objects that appear to be at the highest redshifts. They are so numerous and bright that if they would be early galaxies made out of stars as we know them, they would be too massive and too early in the Universe's timeline.

This population of objects has been studied intensively ever since with a consensus emerging that these host the earliest active galactic nuclei, the sites of the earliest supermassive black holes.
