Workshop on “Observing Universe with AstroSat”
A three days workshop on “Observing Universe with AstroSat” was conducted at Manipal Centre for Natural Sciences (MCNS), Manipal Academy of Higher Education (MAHE) during September 03-05, 2018. 50 participants were selected from 18 institutes/universities from 5 different states (Karnataka, Tamilnadu, Kerala, Maharashtra and West Bengal). The aim of this workshop is to motivate students to pursue higher studies in the field of observational astrophysics in the context of the Indian Space Program. India's first multiwavelength astronomical satellite AstroSat has been launched on 2015. AstroSat with it's multiwavelength observation capabilities has provided a unique platform to study and understand various galactic and extragalactic astrophysical sources.
One of the most important X-ray payload onboard AstroSat is LAXPC. LAXPC operates between 3-80 KeV. UVIT onboard AstroSat observes the universe in broad UV band. In this workshop, the instrument overview, expected scientific outcome from these two instruments was introduced. Also, a detail analysis training session for these two instruments was carried out. Participants were informed that a feedback form will be sent end of December, 2018.
