Star Clusters Around Recoiled Black Holes in the Milky Way Halo
Ryan M. O'Leary, Abraham Loeb
Gravitational wave emission by coalescing black holes (BHs) kicks the remnant BH with a typical velocity of hundreds of km/s. This velocity is sufficiently large to remove the remn…
Gravitational waves from scattering of stellar-mass black holes in galactic nuclei
Ryan M. O'Leary, Bence Kocsis, Abraham Loeb
Stellar mass black holes (BHs) are expected to segregate and form a steep density cusp around supermassive black holes (SMBHs) in galactic nuclei. We follow the evolution of a mult…
Hypervelocity Stars from the Andromeda Galaxy
Blake D. Sherwin, Abraham Loeb, Ryan M. O'Leary
Hypervelocity stars (HVSs) discovered in the Milky Way (MW) halo are thought to be ejected from near the massive black hole (MBH) at the galactic centre. In this paper we investiga…
Dynamical Interactions and the Black Hole Merger Rate of the Universe
Ryan O'Leary, Richard O'Shaughnessy, Frederic Rasio
Binary black holes can form efficiently in dense young stellar clusters, such as the progenitors of globular clusters, via a combination of gravitational segregation and cluster ev…
Production of Hypervelocity Stars through Encounters with Stellar-Mass Black Holes in the Galactic Centre
Ryan M. O'Leary, Abraham Loeb
Stars within 0.1 pc of the supermassive black hole Sgr A* at the Galactic centre are expected to encounter a cluster of stellar-mass black holes (BHs) that have segregated to that…
