(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.
