I will present prompt cusps, a recently identified class of compact dark matter structures with ρ∝r^-1.5 density profiles that form at the onset of structure formation and persist at halo centers. These systems enable new constraints on warm dark matter from dwarf galaxy kinematics, strengthen limits on annihilating dark matter, and offer detection prospects for general cold dark matter...

Explaining the large amplitude of the nano-Hertz stochastic gravitational-wave background observed by pulsar timing arrays (PTAs) typically requires extremely energetic primordial sources. Such mechanisms generically produce large curvature perturbations, which subsequently collapse into ultra-compact mini-halos (UCMHs). If

Nearly 30 years since the ADD proposal to solve the hierarchy problem via large extra dimensions, such scenarios have seen a resurgence in interest in the context of the ‘dark dimension’ - an extra dimension of micron scale motivated by the swampland program. We will begin by reviewing the features of the dark dimension, including the possibility that dark matter could consist of Kaluza-Klein...

The fundamental nature of dark matter so far eludes direct detection experiments, but it has left its imprint in the cosmic large-scale structure. Disentangling this imprint requires accurate modelling of structure formation in non-standard dark matter models, careful handling of astrophysical uncertainties and consistent observations in independent cosmological probes. I will review a...
