submillimetre galaxy

释义与例句

n.
  1. 1.

    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.

    天文

词源

From submillimeter + galaxy. From being a high-redshift galaxy whose emissions are primarily submillimetre-wave radiation (terahertz-radiation (T-wave/T-ray); electromagnetic radiation with wavelengths longer than infrared and shorter than microwave/radiowave).
