The Sweet Sing of the Black Hole

11.06.2020 13:45 – 15:00

In this talk, I want to present a low-energy EFT of gravity where higher orders terms are included as corrections to the EH Lagrangian (typically ~$R^2$ and ~$R^3$). In this framework, I ask the following questions:
• Is there a “Scwhwarzschild” solution in this theory? (Spoiler alert: Yes)
• What is the correction to the Quasinormal Modes around such a black hole?
• What is the speed of gravity waves around such a black hole?
Although those effects are too small to be observable, the results shed some new light about the effect of high energy physics on low-energy processes.
