Scalar fields around black hole binaries in LIGO-Virgo-KAGRA
Soumen Roy, Rodrigo Vicente, Josu C. Aurrekoetxea +2
Light scalar particles arise naturally in many extensions of the Standard Model and are compelling dark-matter candidates. Gravitational interactions near black holes can trigger t…
Self-interacting scalar dark matter around binary black holes
Josu C. Aurrekoetxea, James Marsden, Katy Clough +1
Gravitational waves can provide crucial insights about the environments in which black holes live. In this work, we use numerical relativity simulations to study the behaviour of s…
Symmetry restoration and vacuum decay from accretion around black holes
James Marsden, Josu C. Aurrekoetxea, Katy Clough +1
Vacuum decay and symmetry breaking play an important role in the fundamental structure of the matter and the evolution of the universe. In this work we study how the purely classic…
The effect of wave dark matter on equal mass black hole mergers
Josu C. Aurrekoetxea, Katy Clough, Jamie Bamber +1
For dark matter to be detectable with gravitational waves from binary black holes, it must reach higher than average densities in their vicinity. In the case of light (wave-like) d…
Constraints on galileons from the positions of supermassive black holes
Deaglan J. Bartlett, Harry Desmond, Pedro G. Ferreira
Galileons are scalar field theories which obey the Galileon symmetry and are capable of self-acceleration if they have an inverted sign for the kinetic term. T…
