A New Record Census of Dwarf AGN and a Bimodal M BH - M Scaling Relation with DESI DR1
Researchers used DESI DR1 data to find 1.7 million low-redshift galaxies hosting Active Galactic Nuclei (AGN). They constructed a bimodal scaling relation between black hole mass and stellar mass, revealing two distinct populations of AGN. This study helps map the relationship between galaxies and their central black holes in the low-mass regime.
