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.

SPENDER autoencoder plus k-d tree nearest-neighbor classification on DESI spectra identifies AGN and broad-line AGN at accuracies 0.952 and 0.965, recovering sources missed by single-line diagnostics.
DESI spectra yield radial metallicity gradients in 2291 low-z star-forming galaxies that decline steeply in massive systems, flatten at large radii across all masses, and correlate with size and outer stellar age.
Cooler CGM phases traced by Ca II and Mg II exhibit steeper radial equivalent width profiles than the warmer C IV phase, with host-type differences and stellar-mass dependence.
DESI DR2 yields galaxy luminosity functions showing non-power-law faint-end behavior and bright-end deviations, with good North-South agreement and reduced errors compared to GAMA.
