Gravitational Waves from Axion Stars

Abstract
I will talk about the GW signatures from the collisions of Axion Stars—which are long-lived non-topological solutions of massive scalar fields. I will discuss their stability and their possible end-states, dispersion or Black Hole formation. I will describe the technical challenges and present the GW wave forms of such collisions calculated using the numerical relativity code GRCHOMBO . I will show that for black hole end states, the total gravitational waves energy released in such collisions is more than that of BH-BH collisions of equal masses by a significant amount. If you are interested to explore these exotic events in Virtual Reality, please stay after the question session.
