Comment on: Cosmological black holes are not described by the Thakurta metric
Celine Boehm, Archil Kobakhidze, Ciaran A. J. O'Hare +2
Recently, Hütsi et al.[arXiv:2105.09328] critiqued our work that reconsidered the mathematical description of cosmological black holes. In this short comment, we highlight some of…
Axion helioscopes as solar magnetometers
Ciaran A. J. O'Hare, Andrea Caputo, Alexander J. Millar +1
Axion helioscopes search for solar axions and axion-like particles via inverse Primakoff conversion in strong laboratory magnets pointed at the Sun. Anticipating the detection of s…
Can we overcome the neutrino floor at high masses?
Ciaran A. J. O'Hare
The neutrino floor is a barrier in the parameter space of weakly interacting massive particles (WIMPs) below which discovery is impeded due to an almost irreducible background of n…
A Dark Matter Hurricane: Measuring the S1 Stream with Dark Matter Detectors
Ciaran A. J. O'Hare, Christopher McCabe, N. Wyn Evans +2
The recently discovered S1 stream passes through the Solar neighbourhood on a low inclination, counter-rotating orbit. The progenitor of S1 is a dwarf galaxy with a total mass comp…
Directional axion detection
Stefan Knirck, Alexander J. Millar, Ciaran A. J. O'Hare +2
We develop a formalism to describe extensions of existing axion haloscope designs to those that possess directional sensitivity to incoming dark matter axion velocities. The effect…
Stellar kinematics from the symmetron fifth force in the Milky Way disk
Ciaran A. J. O'Hare, Clare Burrage
It has been shown that the presence of non-minimally coupled scalar fields giving rise to a fifth force can noticeably alter dynamics on galactic scales. Such a fifth force must be…
