Events at IUCAA GWOpen Data Workshop (ODW) by the LIGO-Virgo-KAGRA collaboration | 06 | KHAG L | No. 133 - JULY 2024 Refresher Course on Astronomy and Astrophysics and the online Summer School on Astronomy and Astrophysics The IUCAA chapter of the “GW Open Data Workshop” was organised by the Inter- University Centre for Astronomy and Astrophysics (IUCAA), Pune, and took place over three days from April 18 - 20, 2024, at IUCAA, Pune. The workshopwas an ongoing effort by the LIGO-India scientific collaboration members of IUCAA to provide local college and university participants in Pune with a detailed understanding of gravitational wave data analysis techniques. This was the third consecutive year of organising a workshop in sync with the main Gravitational Wave Open Data Workshop organised by the LIGO-Virgo- KAGRA collaboration. The participants attended online lectures on various topics on gravitational-wave science and were helped with the hands- on sessions on data analysis tutorials. The workshop attracted thirty undergraduate and postgraduate participants from the physics and engineering branches. Over three days, participants engaged in in- depth sessions that enhanced their understanding of actual search and parameter estimation of gravitational wave event s . The wor kshop was coordinated by Apratim Ganguly and Sanjit Mitra.. The Refresher Course on Astronomy and Astrophysics 2024 was held at IUCAA from May 13 - June 14, 2024. It was held concurrently with the Online Summer School on Astronomy and Astrophysics. There were eighteen faculty participants from higher educational institutions located across the country. The lectures covered a wide range of topics, introducing the basic and advanced topics of the field, which included introductory astronomy, optical astronomy techniques, radio astronomy, radiative processes, stellar structure and evolution, the Sun, galaxies, interstellar medium, active galactic nuclei and jets, gamma-ray astronomy, compact objects, black holes, neutron stars and pulsars, gravitational lensing, high-energy astrophysics, fluids and plasmas, gravity, general theory of relativity and cosmology, structure formation. The other interesting topics included gravitational wave astronomy and LIGO, artificial intelligence in astronomy, quantum clocks, and the mega projects in which IUCAA is involved, such as the Thirty Meter Telescope, LIGO, Aditya-L1 and Rubin LSST. There were hands-on sessions on practical statistics using Python, MUSE data analysis, PLUTO
