Binary neutron star mergers with a subsolar mass star
Maxence Corman, William E. East, Jocelyn S. Read
While there are a number of proposed formation channels for subsolar mass compact objects, including black holes formed primordially, or neutron stars that form in collapsar disks,…
GW241011 and GW241110: Exploring Binary Formation and Fundamental Physics with Asymmetric, High-Spin Black Hole Coalescence
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1783
We report the observation of gravitational waves from two binary black hole coalescences during the fourth observing run of the LIGO--Virgo--KAGRA detector network, GW241011 and GW…
Dark photon superradiance: Electrodynamics and multimessenger signals
Nils Siemonsen, Cristina Mondino, Daniel Egana-Ugrinovic +3
We study the electrodynamics of a kinetically mixed dark photon cloud that forms through superradiance around a spinning black hole, and design strategies to search for the resulti…
Multimessenger signals from black hole-neutron star mergers without significant tidal disruption
William E. East, Luis Lehner, Steven L. Liebling +1
We study the multimessenger signals from the merger of a black hole with a magnetized neutron star using resistive magnetohydrodynamics simulations coupled to full general relativi…
Modeling and searching for a stochastic gravitational-wave background from ultralight vector bosons
Leo Tsukada, Richard Brito, William E. East +1
Ultralight bosons, which are predicted in a variety of beyond-Standard-Model scenarios as dark-matter candidates, can trigger the superradiant instability around spinning black hol…
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…
