31. Overview on Ultraheavy Dark Matter

Nirmal Raj (TRIUMF)

"Ultraheavy" dark matter candidates with masses between roughly 10 TeV and the Planck scale present a wide and underexplored parameter space, with rich possibilities of models and cosmic histories. Both current detectors and novel search techniques -- direct and indirect -- are poised to hunt ultraheavy particle dark matter in the coming decade. I will present an overview of these with...

1. Constraints on the nature of dark matter from quadruply-imaged quasars

The abundance and density profiles of dark matter halos on sub-galactic scales, below $10^9 M_{\odot}$ solar masses, depend on the production mechanism, mass, and interactions of the dark matter particle(s). Galaxy-scale strong gravitational lenses provide the ideal observational platform with which to characterize the properties of low-mass halos because lensing depends only on gravity, and...

21. Identifying the fundamental nature of dark matter in the cosmic large-scale structure

Keir Rogers

The fundamental nature of dark matter so far eludes direct detection experiments, but it has left its imprint in the large-scale structure (LSS) of the Universe. Extracting this information requires accurate modelling of structure formation and careful handling of astrophysical uncertainties. I will present new bounds using the LSS on two compelling dark matter scenarios that are otherwise...

15. Dark Matter from a Conformal Dark Sector

Gowri Kurup (University of Oxford)

A compelling solution to the Dark Matter question is that DM particles are part of a “dark sector” with fields uncharged under the SM gauge group. On the other hand, conformal field theories are ubiquitous and appear as fixed points of gauge theories. CFTs are scale-invariant and UV complete. In this work, we consider dark sectors described by conformal field theories and couple to the SM via...
