| 04 | KHAG L | No. 135 - JANUARY 2025 The Gravitational-Wave Instrumentation Workshop (GWIW) was held from November 10-29, 2024. The workshop introduced upper undergraduate and graduate students to GW instrumentation, focusing on various subsystems of the LIGO GW detector. The workshop took a novel approach, where a large portion of the participants' time was spent in IUCAA's in-house laboratories hosted in SITARA. The sixteen participants were divided into groups of three and covered five different modules pertaining to the different subsystems. Each module had an experiment, involving cutting-edge instruments, that each individual group had to conduct. The groups also had to accumulate and analyse data. The theoretical background covering the physical principles governing these experiments was covered in formal lectures. The novelty of the workshop and t h e u n i q u e e x p o s u r e t o G W i n s t r u m e n t a t i o n r e c e i v e d a n overwhelmingly positive response fromthe participants. The resource people were Suresh Doravari, Shivaraj Kandhasamy, S a n j i t M i t r a , a n d M a n a s a d e v i Thirugnanasambandam. The workshop was coordinated by Shasvath J. Kapadia (IUCAA). Baryons Beyond Galactic Boundaries - 2024 The week-long international conference "Baryons Beyond Galactic Boundaries" was organised at IUCAA, Pune from December 02-06, 2024. The primary objective was to bring together leading experts and emerging researchers focused on investigating the diffuse baryons in the Circumgalactic Medium (CGM) and I n t e r ga l ac t i c Med i um ( I GM) . The conference aimed to explore these topics through various observational techniques and hydrodynamical simulations. It offered a comprehensive review of the field's advancements over the past two decades and discussed its future directions. The con f e r ence was a t t ended by 89 participants, nearly half of whom travelled fromabroad. The international participants represented a diverse range of countries, including Australia, France, Germany, Italy, Japan and the USA, highlighting the global reach of the conference and its significance in the international research community.
