Wed Apr 1 2026 12:15 PM: Minimal Dark Matter: Generalized Framework and Direct-Detection Sensitivity

Numerous models of particle dark matter have been proposed, many of
which remain viable given current experimental and observational
constraints. Minimal dark matter is an extremely attractive option since
it envisions the addition of a single SU(2) multiplet to the standard
model, rather than a complicated array of particles and interactions.
However, experimental limits already rule out a subset of minimal dark
matter possibilities and are approaching the predicted phase space of
the remaining candidates. We consider extensions to the minimal dark
matter paradigm, particularly a combination of two multiplets with a
Higgs coupling, and the non-perturbative effects which may alleviate
this experimental pressure.

Fri Apr 17 2026 11:00 AM: The emergence of galaxies in the first billion years

Galaxy formation in the first billion years marks a time of great upheaval in our cosmic history: the first sources of light in the Universe, these galaxies ended the 'cosmic dark ages' and produced the first photons that could break apart the hydrogen atoms suffusing all of space starting the process of 'cosmic reionization'. The past few years have seen cutting-edge instruments such as the James Webb Space Telescope (JWST) provide tantalising glimpses of such galaxies assembling in an infant Universe. Puzzlingly, these observations are also yielding a sample of unexpectedly numerous and large black holes (up to a 100 million solar masses) within the first 600 million years, posing an enormous challenge for galaxy formation models. I will show how this data is providing an unprecedented opportunity to pin down the reionization state of the Universe in addition to providing an unrivalled resource for understanding the reioni
