Simulated differential observations of the Sunyaev-Zel'dovich Effect: Probing the Dark Ages and Epoch of Reionization
Charles Mpho Takalana, Paolo Marchegiani, Geoff Beck +1
This work presents an analytical approach for studying the cosmological 21cm background signal from the Dark Ages (DA) and subsequent Epoch of Reionization (EoR). We simulate diffe…
Axion-like particle searches with MeerKAT and SKA
Ahmed Ayad, Geoff Beck
In the past few years, the search for axion-like particles (ALPs) has grown significantly due to their potential to account for the total abundance of the cold dark matter (CDM) in…
Sensitivity of the Cherenkov Telescope Array for probing cosmology and fundamental physics with gamma-ray propagation
The Cherenkov Telescope Array Consortium, :, H. Abdalla +496
The Cherenkov Telescope Array (CTA), the new-generation ground-based observatory for -ray astronomy, provides unique capabilities to address significant open questions in astrop…
Gamma Rays from UltraCompact Minihaloes: Effects on the Earth's Atmosphere and Links to Mass Extinction Events
M. Sarkis, G. Beck, B. C. Thomas
Recent studies of the effects on the Earth's atmosphere by astrophysical sources, such as nearby gamma-ray bursts or supernovae, have shown that these events could lead to severe c…
Potential of SKA to Detect CDM ALPs with Radio Astronomy
Ahmed Ayad, Geoff Beck
Axion-like particles (ALPs) are light pseudo-scalar particles predicted in many theoretically well-motivated extensions to the standard model of particle physics (SM). The search f…
Radio-Frequency Searches for Dark Matter in Dwarf Galaxies
Geoff Beck
Dwarf spheroidal galaxies have long been discussed as optimal targets for indirect dark matter searches. However, the majority of such studies have been conducted with gamma-ray in…
Sensitivity of the Cherenkov Telescope Array to a dark matter signal from the Galactic centre
The Cherenkov Telescope Array Consortium, :, A. Acharyya +449
We provide an updated assessment of the power of the Cherenkov Telescope Array (CTA) to search for thermally produced dark matter at the TeV scale, via the associated gamma-ray sig…
Indirect detection prospects for d(2380) dark matter
Geoff Beck
A Bose-Einstein condensate of the hexaquark particle known as d(2380) has been recently proposed as a dark matter candidate by the authors in Bashkanov \& Watts 2020. This part…
