Description
Primordial Black Holes (PBHs) may exist, contributing to the Dark Matter abundance. In this talk, we revisit the cosmological bound on PBHs -- driven by the accurate measurements of the anisotropies in the Cosmic Microwave Background (CMB) -- putting under the spotlight the role of the modeling of accretion physics as well as other sources of uncertainty related to PBH properties and the environmental baryonic gas. We present an up-to-date bound from the CMB on heavy PBHs, i.e. between tens to $\mathcal{O}(10^4) \, M_{\odot}$.
