Khagol- 134 (Oct 2024) - ENG

| 03 | KHAG L | No. 134 - OCTOBER 2024 The topics covered were related to the efficient use of large-scale computing resources for Gravitational Wave data and Rachel Lombardi, from the University of Wisconsin-Madison, USA, along with SiddharthMohite, Computational Scientist, Pennsylvania State University, USA conducted the tutorial. The tutorial was attended by thirty participants, including students, post-doctoral scholars and facu l t y f rom va r i ous i ns t i t u t i ons , universities and colleges in India, including IUCAA. analysis and research, using the HTCondor Software Suite at the individual large HTC computing clusters being provided by institutes like IUCAA and also through the Open Science Grid, using several of such resources spread across the entire world. The participants were also introduced to the latest techniques of accessing the LIGO data reliably and quickly anywhere across the LIGO Data Grid through the Open Science Data Federation (OSDF). The tutorial included lectures, hands-on ses s i ons , and t a rge t ed t echn i ca l interactions to solve specific challenges. The tutorial also had sessions on the administration of HTCondor clusters. The participants found this an excellent opportunity to learn from the experts directly. The feedback received from the participants was very encouraging and was app r e c i a t ed by t he b r oade r L I GO computing community. Participants expressed the need for having such tutorials for longer duration and frequently. The tutorial was organised by Sandeep Joshi andSanjit Mitra. Events outside IUCAA Workshop on Relativistic Cosmology: Theoretical and Data Analysis Techniques The Centre of Excellence for Astrophysics and Cosmology at G. H. Raisoni College of Engineering, Nagpur, organised a three- day workshop on Relativistic Cosmology: Theoretical and Data Analysis Techniques,” from July 15 - 17, 2024. The workshop was a dynamic and intellectually stimulating event designed for junior researchers, physicists, and cosmologists passionate about exploring relativity's profound implications on our understanding of the universe. This workshop provided a unique forum for participants to engage in in- depth discussions, share groundbreaking research, and foster collaborations that push the boundaries of our knowledge in these fundamental areas of theoretical physics. The workshop included a series of lectures, presentations, and interactive discussions covering a broad spectrum of topics, including the mathematical foundations of relativity, gravitational waves, black holes, and applying relativistic principles to cosmological models. The introductory lectures on Relativistic Cosmology enabled the participants to gain insights into the latest developments in cosmology. Through the workshop, attendees gained valuable insights, exchanged ideas with peers, and contributed to the collective advancement of our understanding of the cosmos. Whether delving into theoretical frameworks or exploring experimental approaches, the workshop served as a pivotal platform for intellectual exchange, fostering a collaborative spirit among par t i c i pant s and i nsp i r i ng fur ther exploration of the mysteries of the universe.
