| 09 | KHAG L | No. 135 - JANUARY 2025 sessions. The talks and posters presented during NEMA-X covered a wide range of topics, including astrophysical plasma, solar physics, planetary science, black holes and compact objects, galaxies, active galactic nuclei (AGNs), interstellar dust, cosmology, neutrino physics, and machine learning. Ajit Kembhavi, Ranjeev Misra and Kanak Saha from IUCAA, Pune, attended the meeting and provided valuable f e e d b a c k a n d s u g g e s t i o n s f o r strengthening astronomy research in the r e g i o n . T h e i r r e c omme n d a t i o n s empha s i s ed f o s t e r i ng a c ademi c Workshop on Gravitation and Cosmology The workshop was structured as a series of lectures, tutorials, and hands-on sessions and covered a spectrum of topics, including the Mathematical Foundations of General relativity (GR), Raychaudhuri's equations, Space-time singularity, Gravitational Waves (GW), Data analysis in Gravitational waves, and Modified theories of gravity. The resource persons for the The 'Workshop on Gravitation and Cosmology' organised by the Department of Mathematics and Statistics in collaboration with ICARD, Department of Physics, DDU Gorakhpur University, Gorakhpur, U.P., India, sponsored by IUCAA, Pune, was held on October 23-25, 2024. The workshop was proposed for the M.Sc., Ph.D. students and researchers working in the field of General relativity and Cosmology who are passionate about exploring the profound implications of gravitational theory on the understanding of the universe. Fifty participants attended the workshop from all over India, including Bihar, Karnataka, Madhya Pradesh, Maharashtra, Punjab, Uttar Pradesh and West Bengal. workshop were Subenoy Chakraborty (Jadavpur University, Kolkata), who delivered lectures on the Basics of GR and consequences o f Raychaudhur i ' s equations; Apratim Ganguly (IUCAA, Pune) delivered lectures on data analysis of GW; Jibitesh Dutta (NEHU, Shilong) delivered lectures on modified gravitational theory and its applications in cosmology; Shantanu Rastogi (DDU, Gorakhpur University) delivered lecture on measuring scale in the universe. There were three tutorials/hands-on sessions for GW data analysis. The workshop was participatory in nature, w i t h p a r t i c i p a n t s f r om d i v e r s e backgrounds, which was supported by IUCAA under the ICARD programme. It was coordinated by Rajesh Kumar (DDU Gorakhpur University, Gorakhpur) and ApratimGanguly (IUCAA). partnerships and increasing student engagement in different areas of Astronomy. The event was coordinated by Rupjyoti Gogoi (Tezpur University) and Ranjeev Misra (IUCAA).
