1st National Workshop on GEANT4 and its Application to High-Energy Physics and Astrophysics The was held for five days, with workshop sessions split between lectures and tutorials. The lectures covered various aspects of building a application GEANT4 for different types of detectors and examples of the use of in various GEANT4 areas of h i gh-energy and phys i cs An interdisciplinary on workshop GEANT4 and its Application to High-Energy Physics and Astrophysics, jointly organised by TIFR and IUCAA, was held at IUCAA from 05-09 December 2022 is a toolkit to . GEANT4 simulate the interaction of particles (or radiation) withmatter as they pass through it. It primarily simulates detector physics and response in high-energy and physics high-energy astrophysics. The workshop aimed to bring together the user GEANT4 community in India and introduce intermediate to advanced concepts of GEANT4 to graduate students, postdocs and scientific staff who use in their GEANT4 researchwork. astrophysics detectors. The tutorials complemented the lectures, and participants had hands-on sessions on building a few simple . About 28 student GEANT4 applications participants were from different universities and research institutes across India. About 20 national and international experts conducted lectures and tutorials on and its GEANT4 application. The workshop was coordinated jointly by Gulab Dewangan and Sriharsh Tendulkar, TIFR, Mumbai. The Cosmic Crowd in the Universe The symposium was held in hybrid mode with participants from India and abroad. There were about 15 scientific talks The Inter-University Centre for Astronomy and Astrophysics (IUCAA) organised a one- day symposium titled “The Cosmic Crowd in the Universe” on December 19, 2022. The symposium was aimed to provide a platform for researchers to discuss the current status and understanding of the various astrophysical processes inside the densest environment of the universe and pay tribute to eminent astronomer Somak R a y c h a u d h u r y f o r h i s i mme n s e contribution to the field. spanning the whole day and evening. The symposium also included online participants from America, Europe, and Chile. The symposium was summarised and concluded with a presentation by Prof. Varun Sahni (IUCAA) in the evening. The Symposium was organised by Kanak Saha, RanjeevMisra andTarun Saini (IISC, Bangalore).
