TITLE:  Impact of primordial magnetic fields on matter power spectrum ABSTRACT: Primordial magnetic fields (PMFs) offer a simple explanation for the origin of galactic magnetic fields as well as of the purportedly detected magnetic fields in cosmic voids. In the talk, I discuss how PMFs' influence on structure formation can offer a complementary method to […]

TITLE: CMB limits on decaying dark matter: going beyond the ionization threshold ABSTRACT: The temperature and polarization anisotropies of the cosmic microwave background (CMB) have been used to set constraints on decaying dark matter models down to keV masses. In this talk, I will discuss recent work to extend these limits down into the sub-keV […]
