All-sky search in early O3 LIGO data for continuous gravitational-wave signals from unknown neutron stars in binary systems
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1369
Rapidly spinning neutron stars are promising sources of persistent, continuous gravitational waves. Detecting such a signal would allow probing of the physical properties of matter…
Up-down instability of binary black holes in numerical relativity
Vijay Varma, Matthew Mould, Davide Gerosa +3
Binary black holes with spins that are aligned with the orbital angular momentum do not precess. However, post-Newtonian calculations predict that "up-down" binaries, in which the…
Gravitational wave peak luminosity model for precessing binary black holes
Afura Taylor, Vijay Varma
When two black holes merge, a tremendous amount of energy is released in the form of gravitational radiation in a short span of time, making such events among the most luminous phe…
Statistical and systematic uncertainties in extracting the source properties of neutron star - black hole binaries with gravitational waves
Yiwen Huang, Carl-Johan Haster, Salvatore Vitale +3
Gravitational waves emitted by neutron star black hole mergers encode key properties of neutron stars - such as their size, maximum mass and spins - and black holes. However, the p…
Mapping the asymptotic inspiral of precessing binary black holes to their merger remnants
Luca Reali, Matthew Mould, Davide Gerosa +1
Multiple approaches are required to study the evolution of black-hole binaries. While the post-Newtonian approximation is sufficient to describe the early inspiral (even from infin…
Extracting the Gravitational Recoil from Black Hole Merger Signals
Vijay Varma, Maximiliano Isi, Sylvia Biscoveanu
Gravitational waves carry energy, angular momentum, and linear momentum. In generic binary black hole mergers, the loss of linear momentum imparts a recoil velocity, or a "kick", t…
