Constraints on Einstein-dilation-Gauss-Bonnet gravity from black hole-neutron star gravitational wave events
Recent gravitational wave observations allow us to probe gravity in the strong and
dynamical field regime. In this paper, we focus on testing Einstein-dilation Gauss-Bonnet …

Binary boson stars: Merger dynamics and formation of rotating remnant stars
N Siemonsen, WE East - Physical Review D, 2023 - APS
Scalar boson stars have attracted attention as simple models for exploring the nonlinear
dynamics of a large class of ultracompact and black hole mimicking objects. Here, we study …

Multimessenger constraints on radiatively decaying axions from GW170817
The metastable hypermassive neutron star produced in the coalescence of two neutron stars
can copiously produce axions that radiatively decay into O (100) MeV photons. These …

Constraining light QCD axions with isolated neutron star cooling
The existence of light QCD axions, whose mass depends on an additional free parameter,
can lead to a new ground state of matter, where the sourced axion field reduces the nucleon …

Worldline effective field theory of inspiralling black hole binaries in presence of dark photon and axionic dark matter
A bstract We investigate the correction to the potential that gives rise to the bound orbits and
radiation from non-spinning inspiralling binary black holes in a dark matter environment …

Quadratic coupling of the axion to photons
C Beadle, SAR Ellis, J Quevillon, PNH Vuong - Physical Review D, 2024 - APS
We show that the QCD axion couples to the electromagnetic kinetic term at one loop. The
result is that if axions make up dark matter, they induce temporal variation of the fine …
