Pune-based Inter University Centre for Astronomy and Astrophysics (IUCAA) — which has a strong X-ray astronomy group — has been involved in the development of the instruments on board AstroSat. AstroSat — the country’s first and front line dedicated astronomy satellite that was launched by ISRO last year — has reported for the first time that it has observed rapid variability of high energy X-ray emission from a distant binary system that contains a black hole.

This is the first AstroSat result to be declared and is just the beginning of a large number of such discoveries that it is expected to make. An official statement from IUCAA said that Professor Ranjeev Misra and Dr Mayukh Pakhari are members of the scientific team that have reported this result Professor Shyam Tandon, who is the principal investigator for the Ultra-Violet Imaging Telescope (UVIT), while Professor Dipankar Bhatcharyya and his team were involved in the development and calibration of the Cadmium Zinc Telluride Imager (CZTI) and Scanning Sky Monitor (SSM).

They have played a key role in writing the scientific computer codes required to analyse the data which comes from the satellite, testing them and finally interpreted the results.
