India’s first multi-wavelength satellite, AstroSat, has detected extreme-UV (EUV) light from a galaxy, called AUDFs01, 9.3 billion light-years away from earth.
A bilateral organization, CEFIPRA (Centre for the Promotion of Advanced Research) set up by the DST and the Ministry of Europe and Foreign Affairs of France – delved into how galaxies like AUDFs01 grow their stellar mass when the first stars and galaxies become visible.
A team consisting of Professors from Laboratory for studies of Radiation and Matter in Astrophysics and Atmospheres (LERMA), France and Inter- University centre for Astronomy and Astrophysics (IUCAA), India connected by CEFIPRA estimated the recent star formation rate and mass of the gas reservoir in the galaxy.
The multi-wavelength satellite AstroSat, which was launched on September 28, 2015, by the Indian Space Research Organization (ISRO) has five unique X-ray and ultraviolet telescopes working in tandem and has onboard the ultraviolet imaging telescope (UVIT).
