A simple mid-infrared-to-optical color criterion of R-[24]>14 Vega mag results in a robust selection of approximately half of the redshift 2 ultraluminous infrared galaxy (ULIRG) population. These `Dust-Obscured Galaxies', or DOGs, have many properties that suggest that they are good candidates for systems in a transition phase between gas-rich mergers and QSOs.

Dust-obscured Galaxies with Broken Power-law Spectral Energy Distributions Discovered by UNIONS
astro-ph.GA 2025-04 conditional novelty 6.0 of 10

About half of power-law dust-obscured galaxies show broken power-law SEDs, likely heavily obscured AGN, but the fraction is strongly affected by near-infrared survey depth.
