Probing the Fundamental Nature of Particle Dark Matter
Marco Regis, Aritra Basu, Geoff Beck +7
Understanding the fundamental nature of dark matter (DM) is one of the most significant scientific challenges of our time. A compelling hypothesis is that DM consists of a new, yet…
For modified gravity, it's the LITTLE THINGS that matter
Geoff Beck
Dwarf galaxies have long been recognised as important testing grounds for models of dark matter. For instance, it is here where the cusp-core problem is most apparent. In this work…
WIMP Dark Matter Searches in Reticulum II Using MeerKAT
Shibre Semane, Geoff Beck, Sphesihle Makhathini +2
In the last decade radio astronomy has emerged as a powerful technique for detecting signatures of Weakly Interacting Massive Particles (WIMPs). Dwarf spheroidal galaxies (dSphs) a…
Taking quantisation seriously: a farewell to waves
Geoff Beck
The dual wave-particle nature of quantum objects is a notoriously unintuitive feature of quantum theories. However, it is often deemed essential, due to quantum objects exhibiting…
Detecting the -axiverse through parametric resonance
Stephon Alexander, Geoff Beck, Santiago Loane +1
Axions are a leading dark matter candidate. In this work, we study the detectability of a multi-axion-like model, dubbed the -axiverse, that is distinguishable from the string a…
