Far and mid infrared observations of two ultracompact H II regions and one compact CO clump [PDF]
, 2002 Two ultracompact H II regions (IRAS 19181+1349 and 20178+4046) and one compact molecular clump (20286+4105) have been observed at far infrared wavelengths using the TIFR 1 m balloon-borne telescope and at mid infrared wavelengths using ISO.

Submillimeter and Far-Infrared Polarimetric Observations of Magnetic Fields in Star-Forming Regions
Frontiers in Astronomy and Space Sciences, 2019 Observations of star-forming regions by the current and upcoming generation of submillimeter polarimeters will shed new light on the evolution of magnetic fields over the cloud-to-core size scales involved in the early stages of the star formation ...

Low-noise SIS mixer for far-infrared radio astronomy [PDF]
SPIE Proceedings, 2004 We present a low noise SIS mixer developed for the 1.2 THz band of the heterodyne spectrometer of the Herschel Space Observatory. With the launch of the Herschel SO in 2007, this device will be among the first SIS mixers flown in space. This SIS mixer has a quasi-optical design, with a double slot planar antenna and an extended spherical lens made of ...
