Beyond orientation: Evidence for distinct physical regimes among Little Red Dots and Little Blue Dots

L. Barrufet, J. S. Dunlop, M. L. Hamadouche +6

Little Red Dots (LRDs) and Little Blue Dots (LBDs) may represent the same population of compact active galactic nuclei (AGN) observed along different lines of sight. We test this s…

Quiescent Host Galaxies of Extended Quasars Revealed by Spectrophotometric Decomposition

Shengxiu Sun, Linhua Jiang, Zhiwei Pan +27

Previous works of low-redshift quasar host galaxies have focused on compact quasars and found that their host galaxies are mainly star-forming galaxies. Here we present a study of…
