| Video Discription | PROGRAM : GRAVITATIONAL WAVE ASTROPHYSICS (ONLINE) ORGANIZERS : Parameswaran Ajith, K. G. Arun, Sukanta Bose, Bala R. Iyer, Resmi Lekshmi and B Sathyaprakash DATE : 18 May 2020 to 22 May 2020 VENUE : ONLINE Meeting Due to the ongoing COVID-19 pandemic, the original program has been canceled. However, the summer school will be conducted through online lectures. The program involves two components. The first fortnight (18﹣22 May) involves a summer school for students and young researchers, that is part of the annual summer schools on gravitational-wave astronomy. The second fortnight (25 May﹣5 June) involves a workshop for active researchers working on gravitational wave astronomy, astrophysics, and related areas. This year’s summer school will focus on the multimessenger modeling of compact binary mergers, involving four graduate-level courses on numerical relativity, numerical hydrodynamics, and the modeling of short gamma-ray bursts and kilonovae. The workshop will focus on two broad themes: The first week (25 ﹣ 29 May) will focus on compact binary merger physics and multimessenger astrophysics, while the second week (1 ﹣ 5 June) will focus on black hole physics and astrophysics using gravitational-wave observation.
