Abstract

One of the biggest mysteries of the early era of JWST's operation has been "Little Red Dots," compact sources with strange V shaped spectral energy distributions and broad emission lines. These sources have been incredibly hard to model, and over the course of three years, leading theories have ranged from over-massive and over-abundant galaxies that assembled Milky Way levels of stellar mass in the first Gyr of cosmic time to over-massive and over-abundant luminous active galactic nuclei that defy models of black hole assembly.
