Indirect detection of the QCD axion
Luca Visinelli, Bradley Johnson, Bradley J. Kavanagh +3
The QCD axion, originally proposed to solve the strong CP problem in QCD, is a prominent candidate for dark matter (DM). In the presence of strong magnetic fields, such as those ar…
The cosmic history of Primordial Black Hole accretion and its uncertainties
Pratibha Jangra, Daniele Gaggero, Bradley J. Kavanagh +1
Primordial Black Holes (PBHs) have not been experimentally detected so far, but their existence would provide important insights about the early Universe and serve as one of the po…
Axions in Andromeda: Searching for Minicluster -- Neutron Star Encounters with the Green Bank Telescope
Liam Walters, Jordan Shroyer, Madeleine Edenton +5
The QCD axion and axion-like particles are compelling candidates for galactic dark matter. Theoretically, axions can convert into photons in the presence of a strong external magne…
Dark Matter Mounds: towards a realistic description of dark matter overdensities around black holes
Gianfranco Bertone, A. Renske A. C. Wierda, Daniele Gaggero +3
Dark matter overdensities around black holes can be searched for by looking at the characteristic imprint they leave on the gravitational waveform of binary black hole mergers. Cur…
Statistics of magnification for extremely lensed high redshift stars
J. M. Palencia, J. M. Diego, B. J. Kavanagh +1
Microlensing of stars in strongly lensed galaxies can lead to temporary extreme magnification factors (), enabling their detection at high redshifts. Following the disc…
Impact of dark matter spikes on the merger rates of Primordial Black Holes
Pratibha Jangra, Bradley J. Kavanagh, J. M. Diego
Mergers of Primordial Black Holes (PBHs) may contribute to the gravitational wave mergers detected by the LIGO-Virgo-KAGRA (LVK) Collaboration. We study the dynamics of PBH binarie…
