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 ground-based near infrared instrumentation for star formation studies. We describe the unique capability of TIRCAM2 for observations in the polycyclic aromatic hydrocarbon (λcen∼ 3.3 μm) and narrow-band L (λcen∼ 3.59 μm) bands, currently being used by the astronomy community, and of the upcoming TANSPEC, which is being built for India’s largest telescope, i.e. the 3.6-m Devasthal Optical Telescope (DOT). The TIRCAM2 on the 3.6-m DOT was successfully commissioned in June 2016, and the subsequent characterization and astronomical observations are presented here. Based on the successful engineering runs on the 3.6-m DOT, TIRCAM2 has been made available to the Indian and Belgian astronomical community for science observations since Early Science Cycle 2017A (May 2017) onwards. The fabrication of TANSPEC is in an advanced stage and the spectrometer is expected to be commissioned by the end of January 2018.
