Probing dark matter via neutrino-gamma-ray correlations
Geoff Beck
The nature of dark matter is one of the most pressing questions in modern cosmology. Much work has been focussed in the past upon probing potential particle dark matter via gamma-r…
Multi-messenger hunts for heavy WIMPs
Geoff Beck
Heavy neutrinos have a long history of consideration in the literature, in particular related to their role as solutions to the problems of neutrino mass, baryon asymmetry, and pos…
Hunting dark matter in galaxy clusters with non-thermal electrons
Geoff Beck
The electron population inferred to be responsible for the mini-halo within the Ophiuchus galaxy cluster is a steep power-law in energy with a slope of . This is substantially…
Phenomenology of axion-like particles coupling with photons in the jets of active galactic nuclei
Ahmed Ayad, Geoff Beck
Axions or more generally axion-like particles (ALPs) are pseudo-scalar particles predicted by many extensions of the Standard Model of particle physics (SM) and considered as highl…
Probing a cosmic axion-like particle background within the jets of active galactic nuclei
Ahmed Ayad, Geoff Beck
Axions or more generally axion-like particles (ALPs) are pseudo-scalar particles predicted by many extensions of the Standard Model of particle physics (SM) and considered as viabl…
An excess of excesses examined via dark matter radio emissions from galaxies
Geoff Beck
Cosmic-ray and gamma-ray observations have yielded several notable excesses that often lend themselves to explanation by various dark matter annihilation/decay models. In particula…
Making light of gravitational-waves
Justine Tarrant, Geoff Beck, Sergio Colafrancesco
Mixing between photons and low-mass bosons is well considered in the literature. The particular case of interest here is with hypothetical gravitons, as we are concerned with the d…
Probing quantum gravity using high-energy astrophysics
Justine Tarrant, Geoff Beck, Sergio Colafrancesco
The events observed by LIGO indicate the existence of a large population of intermediate mass black holes. This unexpected result lead to a resurgence in the interest in theories o…
Dark matter gets DAMPE at high energies
Geoff Beck, Sergio Colafrancesco
The DArk Matter Particle Explorer (DAMPE) mission revealed a break in the spectrum of cosmic-ray electons and positrons. This is associated with an excess above the expected backgr…
Probing quantum gravity at low energies
Justine Tarrant, Geoff Beck, Sergio Colafrancesco
Planck stars form when a collapsing shell of matter within a black hole reaches the Planck density, roughly equivalent to the mass being compressed into a volumetric size near that…
