Black hole growth through hierarchical black hole mergers in dense star clusters: implications for gravitational wave detections
Fabio Antonini, Mark Gieles, Alessia Gualandris
In a star cluster with a sufficiently large escape velocity, black holes (BHs) that are produced by BH mergers can be retained, dynamically form new BH binaries, and merge again. T…
Millisecond pulsars and the gamma-ray excess in Andromeda
Giacomo Fragione, Fabio Antonini, Oleg Y. Gnedin
The Fermi Gamma-Ray Space Telescope has provided evidence for diffuse gamma-ray emission in the central parts of the Milky Way and the Andromeda galaxy. This excess has been interp…
The impact of vector resonant relaxation on the evolution of binaries near a massive black hole: implications for gravitational wave sources
Adrian S. Hamers, Ben Bar-Or, Cristobal Petrovich +1
Binaries within the sphere of influence of a massive black hole (MBH) in galactic nuclei are susceptible to the Lidov-Kozai (LK) mechanism, which can drive orbits to high eccentric…
A Triple Origin for the Heavy and Low-Spin Binary Black Holes Detected by LIGO/Virgo
Carl L. Rodriguez, Fabio Antonini
We explore the masses, merger rates, eccentricities, and spins for field binary black holes driven to merger by a third companion through the Lidov-Kozai mechanism. Using a populat…
A hypervelocity star with a Magellanic origin
Denis Erkal, Douglas Boubert, Alessia Gualandris +2
Using proper motion measurements from Gaia DR2, we probe the origin of 26 previously known hypervelocity stars (HVSs) around the Milky Way. We find that a significant fraction of t…
