1.3-mm observation
(observation frequency useful for detecting dust)
1.3-mm observation of electromagnetic radiation (EMR) is useful for detecting how much cold
dust is somewhere. The wavelength is within an
atmospheric window, and the black-body radiation
of cold dust produces considerable
1.3-mm signal with sufficiently few other sources
to make it useful for finding
dust clouds and protoplanetary disks.
Dust is optically thin at this
wavelength so the signal corresponds to the mass of the dust cloud.
The window allows observation of a number of molecular lines
as well as the continuum at that wavelength.
The Submillimeter Array (SMA) and other similar telescopes image and
survey at this wavelength.
