The Relativistic Universe

This book is a record of the complete proceedings of the first International Symposium on Recent Developments in Relativistic Astrophysics (ISRA 2023), convened on December 11 – 13 at Shri Ramasamy Memorial (SRM) University Sikkim, Gangtok, India. The present volume contains contributions by 50 researchers and distinguished scientists across the globe who are well known scholars in their own right. This volume is a collection of original research reports and reviews on contemporary issues on relativistic astrophysics, astroparticle physics, gravitation, cosmology, and related quantum physics, is a tribute to Prof. Banibrata Mukhopadhyay, a leading Indian astrophysicist of our times, commemorating his 50th birth anniversary, in light of Mukhopadhyay’s illustrious academic journey. This Festschrift covers a wide range of topics that includes physics of accretion and relativistic jets, X-ray and gamma-ray astronomy, astrophysical fluids and plasma, physics of compact objects, gravitational wave astrophysics, cosmic ray physics, the dark matter problem and cosmological issues, gravity physics and gravity-quantum interface, astrochemistry and origin of life, and space instrumentation. A majority of the authors were/are Mukhopadhyay’s PhD students, post-doctoral fellows and his research collaborators.
