hot DOG

(hot dust-obscured galaxy, hot dust-obscured object)
(high-energy galaxy with a lot of dust)

About 1000 galaxies dubbed hot DOGs (hot dust-obscured galaxy or hot dust-obscured object) have been seen by WISE, having 1000 times the electromagnetic radiation as the Milky Way and largely as old as 10 billion years (redshifts in 2 to 4 range). They may be obscured quasars/active galactic nuclei.
