Nonlinear Stability of Kerr-Sen Black Holes in Merging Binaries
Andrew Carroll, Eric W. Hirschmann, Hyun Lim +3
We investigate the stability of Kerr-Sen black holes, which arise in Einstein-Maxwell-dilaton-axion theory. Within a numerical relativity framework, we perform head-on binary black…

Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…

Black-hole binaries and waveforms in Quadratic Gravity
Aaron Held, Hyun Lim
We report on the first numerical-relativity simulations of black-hole binaries that deviate from General Relativity due to quadratic-curvature corrections. Said theory of Quadratic…
