Black-hole head-on collisions in higher dimensions
William G. Cook, Ulrich Sperhake, Emanuele Berti +1
The collision of black holes and the emission of gravitational radiation in higher-dimensional spacetimes are of interest in various research areas, including the gauge-gravity dua…
Long-lived inverse chirp signals from core collapse in massive scalar-tensor gravity
Ulrich Sperhake, Christopher J. Moore, Roxana Rosca +3
This letter considers stellar core collapse in massive scalar--tensor theories of gravity. The presence of a mass term for the scalar field allows for dramatic increases in the rad…
Gravitational Waves from Binary Black Hole Mergers Inside of Stars
J. M. Fedrow, C. D. Ott, U. Sperhake +4
We present results from a controlled numerical experiment investigating the effect of stellar density gas on the coalescence of binary black holes (BBHs) and the resulting gravitat…
