The Department of Physics, Faculty of Mathematics and Natural Sciences, Universitas Gadjah Mada (FMIPA UGM) successfully held a Public Lecture on Thursday, September 25, 2025, featuring Prof. Dr.rer.nat. Bobby Eka Gunara, S.Si., M.Si. from the Physics Study Program, Bandung Institute of Technology (ITB) as the invited speaker. The event took place in Meeting Room I, Department of Physics FMIPA UGM, from 08.30 to 10.00 a.m. (WIB).
The lecture carried an engaging theme delivered directly by Prof. Bobby, entitled:
“In this talk we will discuss some basic properties of static black holes in four and higher dimensions. Then, we will point out some of our recent works in black hole physics.”
In his presentation, Prof. Bobby explored various fundamental aspects of static black holes in both four and higher dimensions, explaining how these concepts play a crucial role in understanding the structure of space-time within general relativity, and their connections to modern theoretical physics, including field theory and quantum gravity. Furthermore, he introduced recent research findings from his research group, which focuses on black hole physics and higher-dimensional space-time geometry—a field closely related to developments in modern cosmology and string theory.
The event received enthusiastic participation from attendees, including undergraduate, master’s, and doctoral students, as well as members of the general public with a keen interest in theoretical physics. Following the presentation, participants actively engaged in discussions, posing insightful questions about black hole phenomena, space-time stability, and future research directions in this field. The discussion session was lively and interactive, reflecting the strong interest and curiosity of the audience.
This public lecture also served as an important opportunity to enhance academic understanding and scientific insight among the UGM Physics community, particularly in the areas of astrophysics and theoretical gravity. Through this event, it is expected that stronger research collaborations between UGM and ITB will continue to develop, fostering the exchange of ideas and the strengthening of national research networks in theoretical physics and cosmology.
This lecture represents part of the Department of Physics FMIPA UGM’s ongoing commitment to providing high-quality academic activities by inviting distinguished experts in their respective fields, with the goal of enriching the knowledge and broadening the perspectives of students and researchers within the UGM academic community.
