Multi-epoch spectroscopy of 33 ECLEs shows coronal lines emitted at intermediate radii with log(distance)-log(black hole mass) slopes of 0.63 and 0.69 for [O III] and [Fe VII], consistent with photoionization setting the radii.
DESI DR1 yields 314k high-mass and 9.6k dwarf AGN, extending the M_BH-M_star relation to log M_star ~7.8 and suggesting two evolutionary pathways for galaxies and black holes.
DESI DR2 identifies 50,088 galaxies with moderate and 27,420 with strong evidence for down-the-barrel NaI D absorption revealing inflows at ~20 km/s and multiple accretion pathways at z < 0.6.
