Abstract
We present a brief description of the activities of the infrared astronomy group of Tata Institute of Fundamental Research with special emphasis on the near-infrared instrumentation for star formation studies using 2 - 4-meter class Indian ground-based telescopes.
Highlights
The central research theme of the infrared astronomy (IRA) group at Tata Institute of Fundamental Research (TIFR) is the study of interstellar medium (ISM) in relation to star formation in our Galaxy and nearby galaxies
We describe the technical details of TIRCAM2, TIFR Near Infrared Spectrometer and Imager (TIRSPEC) and TIFR-ARIES Near Infrared Spectrometer (TANSPEC) for star fomation studies in India
The TIFR Near Infrared Imaging Camera-I (TIRCAM1) having a 58 × 62 pixels InSb focal plane array (FPA), was the first array camera developed by our group
Summary
The IRA group designed and built the TIFR Near Infrared Spectrometer and Imager (TIRSPEC) in collaboration with M/s Mauna Kea Infrared, LLC, Hawaii (hereafter MKIR) during the 2007-2012 five-year period, in operation on the side port of the 2-meter Himalayan Chandra Telescope (HCT), Hanle (Ladakh), India, at an altitude of 4550 meters above mean sea level (see details in Ojha et al 2012a, Ninan et al 2014). The IRA group has upgraded the TIFR Near Infrared Imaging Camera-II (TIRCAM2) (Ojha et al 2012b, Naik et al 2012) which was This instrument has been tested by the IRA group at the 3.6-meter Devasthal Optical Telescope (DOT) and is being used by Indian astronomers since May 2017 onwards.
