Scientists install first-of-its-kind infrared observatory
Chennai, Dec 31, 2015, DHNS
In another milestone in space technology, ISRO has said Indian scientists have installed 1.2 m Infrared Telescope at Mount Abu, the first major facility in the country designed for ground-based infrared observations of celestial objects.
The observatory is located 1680 meters above mean sea level atop the Gurushikhar peak in Aravali range in Rajasthan’s Mount Abu, an ISRO official told Deccan Herald Wednesday.
"After a suitable astronomical site survey of several locations, Gurushikhar, the highest peak of Aravali range in Mt Abu, Rajasthan, was found most appropriate due to its low water vapour, more than 220 observable nights with reasonably good seeing and the site's vicinity to Physical Research Laboratory (PRL) - (240 kms).
The 1.2 m Infrared Telescope at Mt. Abu is situated at the geographic location of Lat.: 24.65 N; Long.: 72.78 E; and Alt.:1680 m with an astronomical seeing of » 0.9 arc sec (best); and a median of » 1.2 arc sec.
Highlights of science from Mt Abu observatory
- Detection of a helium nova;
- Understanding Peculiar Novae V838 Mon / V4332 Sgr;
- Dust and Molecular Formation in Novae;
- Detection of structure and asymmetry in the carbon star IRC10216;
- Detection of H2 out°ows from the low mass YSO RNO 91;
- Detection of H2 in massive star forming regions IRAS 06061+2151;
- Detection of Quadrupolar Lobes in Planetary Nebula NGC 4361;
- Velocity Field Mapping in the HII region in M8;
- Detection of dust features in Elliptical Galaxies;
- Dust properties from polarimetry of Comets
