Terahertz Far-Infrared Spectroscopy VI. Astronomical Observations in the Submillimeter-wave and Terahertz Region
Journal of the Spectroscopical Society of Japan
The submillimeter-wave and terahertz region, whose wavelength is from 1mm to 0.1mm, is a frontier not only in spectroscopy but also in astronomy, but it will rapidly develop in the near future. In this article, the astronomical application in this wavelength region is reviewd both from technical and scientific points of view. As for the detection technique, we particularly focus on the heterodyne detection.doi:10.5111/bunkou.54.356 fatcat:27linawh6zhh3ikvcnsyr3mgd4
