The observations showed that the Saguaro’s nucleus shares several characteristics with distant little red dots. This simulation suggests that many distant little red dots may appear isolated because current telescopes cannot detect their faint environments. Its compact red appearance suggests that little red dots are a phase of highly active supermassive black holes. That kind of combination could explain the lack of X-ray emission that we see from all other little red dots. A Cosmic Bias May Hide The Galaxies Behind Little Red DotsThe researchers propose that many little red dots may not be a separate category of galaxy.
