INFRA-RED and OPTICAL ASTRONOMY

Far Ifrared Astronomy

Study of star forming regions (e.g., H II regions, molecular clouds and clumps, outflow sources) using the TIFR 1 meter balloon borne Far Infrared (FIR) telescope, with a pointing accuracy of about 20 arc sec rms. Currently a simultaneously viewing two band FIR photometer using He3 cooled (0.3 K) bolometer arrays (12 channel), is in regular use for diffraction limited mapping at 100 - 200 micron bands. The telescope is flown (1-2 times /year) from TIFR Balloon Facility at Hyderabad in central India.

Near Infrared Astronomy

A near infrared (J, H & K) imaging camera based on an Indium Antimonide array (SBRC 58 x 62) is under development. It will be used from the ground based near infrared / optical telescopes within the country, for various imaging programmes.
