submillimeter astronomy
(submillimetre astronomy)
(astronomy observation and analysis of borderline infrared EMR)
Submillimeter astronomy (or submillimetre astronomy,
depending upon the locality's spelling of "meter/metre") is
the branch of astronomy dealing with the observation
and analysis the longest-wavelength infrared radiation
from astronomical sources. There is no standard precise definition
of the range, but the range 450 μm to 1 mm is clearly part of it.
The atmosphere affects observation within the submillimeter range,
but high altitude improves such observations substantially,
to the point that the range has become very useful in astronomical study.
Millimeter astronomy, by definition, applies to longer
wavelengths, but many telescopes span a range substantially
extending both above and below a millimeter, and the choice of term
incorporated in the telescope's name seems to be a matter of
preference and the
unwieldy phrase millimeter/submillimeter astronomy is sometimes
used as more accurate.
At least some of the submillimeter range is within the range for
which radio interferometry methods can be adapted,
which yield the highest angular resolution imaging achieved.
The submillimeter range is used for investigating
molecular clouds and star formation, and
star-forming galaxies (e.g., submillimeter galaxies).
Some current and planned submillimeter-capable telescopes:
There are plans to relocate and revive these past telescopes:
