Probing supermassive black hole seed scenarios with gravitational wave measurements
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
The process whereby the supermassive black holes populating the centers of galaxies have been assembled remains to be established, with the relative importance of seeds provided by…
What is the source of the PTA GW signal?
John Ellis, Malcolm Fairbairn, Gabriele Franciolini +7
The most conservative interpretation of the nHz stochastic gravitational wave background (SGWB) discovered by NANOGrav and other Pulsar Timing Array (PTA) Collaborations is astroph…
Search for dark matter annual modulation with DarkSide-50
50 Collaboration, P. Agnes, I. F. M. Albuquerque +142
Dark matter induced event rate in an Earth-based detector is predicted to show an annual modulation as a result of the Earth's orbital motion around the Sun. We searched for this m…
Gravitational Waves from SMBH Binaries in Light of the NANOGrav 15-Year Data
John Ellis, Malcolm Fairbairn, Gert Hütsi +4
The NANOGrav Collaboration has recently announced evidence for nHz gravitational waves (GWs), in the form of a Hellings-Downs angular correlation in the common-spectrum process tha…
On Stellar Migration from Andromeda to the Milky Way
Lukas Gülzow, Malcolm Fairbairn, Dominik J. Schwarz
Recent Gaia observations suggest that some hypervelocity stars (HVSs) might originate from outside the Galaxy. We ask if these HVSs could come from as far as Andromeda. Therefore,…
Axion Star Explosions: A New Source for Axion Indirect Detection
Miguel Escudero, Charis Kaur Pooni, Malcolm Fairbairn +3
If dark matter is composed of axions, then axion stars form in the cores of dark matter halos. These stars are unstable above a critical mass, decaying to radio photons that heat t…
