submillimeter galaxy

submillimeter galaxy noun: a type of starburst galaxy that primarily emits radiation in the sub-mm/T-hertz range. Due to the extreme dustiness of the galaxy, they are visible mostly in infrared emissions at their redshift, which are subsequently redshifted into the submm/THz range by Hubble expansion.
