The crust of dark-matter admixed neutron stars: bulk properties and torsional oscillations

Jiayi Zhang, Hector O. Silva

We study how dark matter (DM) impacts the crust and the spectrum of torsional crust oscillations of dark-matter-admixed neutron stars (DANSs). We construct two-fluid equilibrium so…

Nonradial oscillations of stratified neutron stars with solid crusts: Mode characterization and tidal resonances in coalescing binaries

Yong Gao, Hao-Jui Kuan, Cheng-Jun Xia +2

Dynamical tides of neutron stars in the late stages of binary inspirals provide a viable probe into dense matter through gravitational waves, and potentially trigger electromagneti…

Black hole spectroscopy: from theory to experiment

Emanuele Berti, Vitor Cardoso, Gregorio Carullo +70

The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…

Eikonal gravitational-wave lensing in Einstein-aether theory

Julius Streibert, Hector O. Silva, Miguel Zumalacárregui

Einstein-aether theory provides a model to test the validity of local Lorentz invariance in gravitational interactions. The speed of gravitational waves as measured from the binary…

Breaking black-hole uniqueness at supermassive scales

Astrid Eichhorn, Pedro G. S. Fernandes, Aaron Held +1

In general relativity, all vacuum black holes are described by the Kerr solution. Beyond general relativity, there is a prevailing expectation that deviations from the Kerr solutio…
