Gravitational wave signatures of ultralight vector bosons from black hole superradiance
Nils Siemonsen, William E. East
In the presence of an ultralight bosonic field, spinning black holes are unstable to superradiance. The rotational energy of the black hole is converted into a non-axisymmetric, os…
Fate of a neutron star with an endoparasitic black hole and implications for dark matter
William E. East, Luis Lehner
We study the dynamics and observational signatures of a neutron star being consumed by a much less massive black hole residing inside the star. This phenomenon could arise in a var…
Einstein-Vlasov Calculations of Structure Formation
William E. East, Radosław Wojtak, Frans Pretorius
We study the dynamics of small inhomogeneities in an expanding universe collapsing to form bound structures using full solutions of the Einstein-Vlasov (N-body) equations. We compa…
Binary neutron star mergers: Effects of spin and post-merger dynamics
William E. East, Vasileios Paschalidis, Frans Pretorius +1
Spin can have significant effects on the electromagnetic transients accompanying binary neutron star mergers. The measurement of spin can provide important information about binary…
Extreme Gravity and Fundamental Physics
B. S. Sathyaprakash, Alessandra Buonanno, Luis Lehner +26
Future gravitational-wave observations will enable unprecedented and unique science in extreme gravity and fundamental physics answering questions about the nature of dynamical spa…
Exploring the sensitivity of gravitational wave detectors to neutron star physics
Denis Martynov, Haixing Miao, Huan Yang +14
The physics of neutron stars can be studied with gravitational waves emitted from coalescing binary systems. Tidal effects become significant during the last few orbits and can be…
