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…
Elements of reality in quantum mechanics
Geoff Beck
The notion of the Einstein-Podolsky-Rosen (EPR) "element of reality" is much discussed in the literature on the foundations of quantum mechanics. Recently, it has become particular…
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…
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…
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…
A radio-frequency WIMP search with the MeerKAT Galaxy Cluster Legacy Survey
Natasha Lavis, Michael Sarkis, Geoff Beck +1
Radio-frequency, indirect dark matter searches have recently been gaining prevalence, due to the high sensitivity and resolution capabilities of the new generation of radio interfe…
