Oral presentation in parallel session
The idea of dark matter in the form of primordial black holes has seen a recent revival triggered by the LIGO detection of gravitational waves from binary black hole mergers. In this context, it has been argued that a large initial clustering of primordial black holes can help alleviate the strong constraints on this scenario. In this work, we show that, on the contrary, with large initial...

A dark photon is a well-motivated new particle which, as a component of an associated dark sector, could explain dark matter. One strong limit on dark photons arises from excessive cooling of supernovae. We point out that even at couplings where too few dark photons are produced in supernovae to violate the cooling bound, they can be observed directly through their decays. Supernovae produce...

Dark Matter (DM) Weakly Intercactive Massive Particles (WIMPs) are expected to produce a gamma-ray emission via annihilation; on the other hand this signal should trace the matter distribution being originated from DM structures evolved from primordial perturbations.
The anisotropies of the unresolved component of the extra-galactic gamma-ray background (UGRB) hosts valuable information on...
