Spin-Dependent Dark Matter-Electron Interactions

Direct searches of sub-GeV dark matter (DM) through its scattering with electrons have attracted lots of attention in recent years. Stringent exclusion limits placed on the spin-independent interactions are reported, and will be improved in …

Primordial Black Holes as a dark matter candidate

Primordial Black Holes (PBHs) are black holes formed in the early Universe, for instance from the collapse of large density perturbations generated by inflation. The discovery of gravitational waves from mergers of ~10 Solar mass black hole binaries …

Hunting for sub-GeV dark matter with gas-based detectors

In this talk, I’ll discuss ideas for new approaches in the hunt for light dark matter was gas-based detectors. Firstly, I’ll discuss the sensitivity that may be achievable through the process of electron ionisation of gas targets in a Spherical …

Searching for sub-GeV dark matter

The non-observation of evidence for conventional dark matter candidates such as WIMPs has led to a growing interest in less explored mass ranges. In this talk I will give an overview of the phenomenology of sub-GeV dark matter. I will explain how we …

Venturing into the neutrino fog

The last few years have seen the largest underground dark matter searches rapidly approach their purported ultimate sensitivity limit, which is increasingly being referred to as the "neutrino fog". An experiment reaches the neutrino fog went it …

Dark Matter Puzzles from Indirect Searches

The nature and origin of dark matter is one of the key unresolved questions of fundamental physics. Astrophysical and cosmological data provide powerful probes of dark matter properties, although to date no signal has been confirmed. I will discuss a …

Dark Matter Capture in Stars

The capture of dark matter in stars provides a cosmic laboratory in which to study the nature of dark matter particles and their interactions. We outline an improved treatment of the dark matter capture process, which correctly incorporates a number …

Direct detection of dark matter - a theorist’s perspective

Measurement of a signal in direct detection of a hypothetical particle constituting the dark matter in the Universe would provide arguably the most convincing proof of its nature. The problem is that we do not really know what the dark matter is. …

Axion Dark Matter

The axion is a hypothetical particle motivated by the strong CP problem of elementary particle physics and by the dark matter problem of cosmology. Cold dark matter axions are naturally produced during the QCD phase transition in the early universe …
