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.

A major part of this document revolves around evolution and diversification of Mukhopadhyay's own research and his accomplishment, and subsequent evolution of research of his thirty odd doctoral students and post doctoral fellows into diverse fields of astronomy and space science. The book has been compiled in such a manner so as to present an overview of the contemporary research in relativistic astrophysics and related fields in space science, pointing out future perspectives, and updating with the latest and most impactful developments in the field. This volume would prove to be beneficial to potential graduates, doctoral students, young and professional researchers and academicians alike.

Dr. Shubhrangshu Ghosh pursued his PhD at the Indian Institute of Astrophysics, and obtained his PhD in 2010 from Jadavpur University. He did his initial doctoral studies at the Max Planck Institute for Radio Astronomy, as a DAAD Fellow. Thereafter he worked as a Post Doctoral researcher at several places in India and abroad, namely Indian Institute of Science, Academia Sinica, Taiwan, Tata Institute of Fundamental research, Bose Institute etc. His research interest primarily lies in theoretical high energy astrophysics, compact objects, black hole astrophysics, accretion and jets, dark matter, gravitational wave astrophysics, modified gravity and cosmology. He is a member of the Square Kilometer Array (SKA) Science Working Group. Dr. Ghosh is currently serving as a Chairperson of Center for Astrophysics, Gravitation and Cosmology (CAGC) & Faculty, Department of Physics, Shri Ramasamy Memorial (SRM) University Sikkim.

Prof A R Rao joined the Department of Astronomy and Astrophysics, Tata Institute of Fundamental Research as a research trainee and completed his PhD in 1985. During 1987-88 he was a visiting professor at the Danish Space Research Institute, Denmark working on the WATCH instrument launched onboard the Granat satellite of Russia. His primary research interest is in High Energy Astrophysics, X-ray Astronomy, and X-ray Instrumentation, developing X-ray instruments for space observations and configuring space payloads for diverse applications. He was the co-investigator/ Principal Investigator of many space payloads including the highly successful Indian X-ray Astronomy Experiment (IXAE) and the CZT- Imager for the ASTROSAT satellite. Professor Rao retired as a Professor from Tata Institute of Fundamental Research.
