Piercing of a boson star by a black hole

Resumo:

Dark matter is one of the biggest mysteries in physics. Could it be made of new light particles that form self-gravitating structures called boson stars? In this talk, I will explore what happens when a black hole collides with a boson star. Using numerical simulations in general relativity, I will show how the black hole swallows most of the boson star material and emits gravitational waves. I will also discuss the formation of a “gravitational atom” as a remnant of the collision. This talk will shed light on the nature and fate of these exotic objects in our universe.
