We present the implications for cosmic inflation of the Planck 2018 data release, reviewing the constraints on slow-roll inflationary models, on features in the primordial power spectrum, on isocurvature perturbations. We then discuss the capabilities of future observations to improve some of the current constraints.
I will review the theoretical and observational status of
stochastic gravitational wave (GW) backgrounds as a probe of early Universe cosmology, reviewing the main sources such as inflation, (p)reheating, first order phase transitions, and general topological defects.
Primordial Black Holes (PBHs) are black holes formed in the early Universe, for instance from the collapse of large density perturbations generated by inflation. The discovery of gravitational waves from mergers of ~10 Solar mass black hole binaries has led to increased interest in PBHs as a dark matter candidate. I will review the formation of PBHs and the limits on their abundance, with...
