High-Resolution Imaging Spectroscopy at Terahertz Frequencies
1990
International Astronomical Union Colloquium
AbstractHISAT, a multi-element heterodyne interferometer attached to Space Station Freedom, will provide spectroscopic images with unprecedented detail of those submillimeter lines of C,O and C+which are critical diagnostics of UV excitation in the Galaxy. With the arcsecond angular resolution achievable from the space station, HISAT will reveal:– The distribution of sources of ultraviolet radiation in the Galaxy;–The effective temperature of the UV radiation as a function of galactocentric
