Submillimetre astronomy
Submillimetre astronomy
or
submillimeter astronomy
(see
spelling differences
) is the branch of
observational astronomy
that is conducted at submillimetre wavelengths (i.e.,
terahertz radiation
) of the
electromagnetic spectrum
. Astronomers place the submillimetre waveband between the
far-infrared
and
microwave
wavebands, typically taken to be between a few hundred
micrometres
and a
millimetre
. It is still common in submillimetre astronomy to quote wavelengths in 'microns', the old name for micrometre.
