Explore advanced gravitational physics in this research seminar where Ricardo Medina from UFEI presents his work on determining self-force corrections to the equation of the separatrix of a Schwarzschild black hole. Delve into the mathematical framework of general relativity and black hole physics as the speaker discusses how self-force effects modify the critical boundary that separates bound and unbound particle trajectories around black holes. Learn about the theoretical foundations of gravitational self-force theory, its applications to black hole spacetimes, and the computational methods used to calculate these corrections. Understand the significance of these findings for gravitational wave astronomy and the modeling of extreme mass ratio inspirals, where small objects spiral into supermassive black holes. This technical presentation is part of the ICTP-SAIFR São Paulo Research Group meetings in Astrophysics and Cosmology, providing insights into cutting-edge research in theoretical gravitational physics and its implications for our understanding of black hole dynamics and gravitational wave sources.
