Journal ArticleDOI
Neutron star mergers as a probe of modifications of general relativity with finite-range scalar forces
Laura Sagunski,Laura Sagunski,Jun Zhang,Jun Zhang,Matthew C. Johnson,Matthew C. Johnson,Luis Lehner,Mairi Sakellariadou,Mairi Sakellariadou,Steven L. Liebling,Carlos Palenzuela,David Neilsen +11 more
TL;DR: In this paper, the authors investigated how future observations of gravitational radiation from binary neutron star mergers might provide constraints on finite-range forces from a universally coupled massive scalar field.
Journal ArticleDOI
Prospects for axion searches with Advanced LIGO through binary mergers
Junwu Huang,Matthew C. Johnson,Matthew C. Johnson,Laura Sagunski,Laura Sagunski,Mairi Sakellariadou,Jun Zhang,Jun Zhang +7 more
TL;DR: In this paper, the first post-Newtonian corrections to the orbital dynamics, radiated power, and gravitational waveform for binary neutron star mergers in the presence of an axion were calculated using an effective field theory approach.
Journal ArticleDOI
Perturbations of stealth black holes in degenerate higher-order scalar-tensor theories
TL;DR: In this paper, the authors investigate the physical perturbations about the Schwarzschild-de Sitter black holes and find that the odd-parity tensor perturbation behaves in a way indistinguishable to general relativity.
Journal ArticleDOI
Dynamic signatures of black hole binaries with superradiant clouds
Jun Zhang,Huan Yang,Huan Yang +2 more
TL;DR: In this paper, the effects of the cloud on the orbits of nearby compact objects were investigated, in particular, the dynamical friction and the backreaction due to level mixing, and the enhanced capture rate of stellar mass black holes could accelerate hierarchical mergers, with a higher generation merger product being more massive than the mass threshold predicted by supernova pair instability.
Journal ArticleDOI
Gravitational floating orbits around hairy black holes
TL;DR: In this paper, the authors show that the superradiant growth of a light axion field around the rotating black holes may be the source of a gravitational floating orbit for black holes with rotating hairs.
