Online Seminar “Quantum Improved Regular Kerr Black Holes”

Star-UBB Seminar Series:- Quantum Improved Regular Kerr Black Holes

In this talk, the speaker will discuss the quantum improvement of Kerr black holes with mass-dependent scale identifications in asymptotically safe gravity. His team and he find that a physically sensible identification can only be a function of M r and the area A=4π(r²+a²) where M is the mass of the black hole and a is an angular momentum parameter. They then discuss various properties of the rotating quantum black holes for a simple choice of the identification. They show that the resulting regular rotating black holes have the following nice properties:
(i) admitting a consistent black hole thermodynamics at the horizon,
(ii) resolving the ring singularity,
(iii) partially eliminating closed time-like curves present in the classical Kerr black holes.

Scientific and Technological Advanced Research- Babeș-Bolyai University(Star-UBB) Seminar Series in Gravitation, Cosmology and Astrophysics

Presently a period of rapid and intense change are being witnessed in our understanding of the gravitational force, at a rate that is quickly increasing since the important observational discoveries of the late 1990s. With the advent of new observational techniques, the emergence of important cosmological and astrophysical paradigms can be seen that lead to a deep change in our understanding of the Universe. Astronomical observations strongly suggest that at large scales the force of gravity may not behave according to standard general relativity, and that a generalization of the gravitational action, either at the geometric level, or at the matter level, may be required for a full understanding of the gravitational interaction.

The goal of the present seminar is to bring Theoretical Gravitational Physics closer to the observations and experiments, and to discuss current topics in general relativity, high-energy physics, astrophysics and cosmology.
