Neutron star -- axion star collisions in the light of multi-messenger astronomy
Tim Dietrich, Francesca Day, Katy Clough +2
Axions are increasingly favoured as a candidate particle for the dark matter in galaxies, since they satisfy the observational requirements for cold dark matter and are theoretical…
Axion star collisions with black holes and neutron stars in full 3D numerical relativity
Katy Clough, Tim Dietrich, Jens C. Niemeyer
Axions are a potential dark matter candidate, which may condense and form self gravitating compact objects, called axion stars (ASs). In this work, we study for the first time head…
Full 3D Numerical Relativity Simulations of Neutron Star -- Boson Star Collisions with BAM
Tim Dietrich, Serguei Ossokine, Katy Clough
With the first direct detections of gravitational waves (GWs) from the coalescence of compact binaries observed by the advanced LIGO and VIRGO interferometers, the era of GW astron…
Black hole interference patterns in flavour oscillations
Jean Alexandre, Katy Clough
Motivated by neutrino astronomy, we consider a plane wave of coupled and massive flavours, scattered by a static black hole, and describe analytically and numerically the correspon…
On the difficulty of generating gravitational wave turbulence in the early universe
Katy Clough, Jens C. Niemeyer
A recent article by Galtier and Nazarenko [1] proposed that weakly nonlinear gravitational waves could result in a turbulent cascade, with energy flowing from high to low frequency…
