Cosmology Seminar

The next cosmology seminar takes place on Wednesday 29th of May, seminar room E349 at 2pm. Our guest speaker will be Eemeli Tomberg from the Lancaster University (Lancaster, United Kingdom).

At 2pm, room E349, Eemeli Tomberg (Lancaster University), will be talking about

Primordial black holes and stochastic inflation

Quantum fluctuations from cosmic inflation give rise to the macroscopic structures of the universe. The strongest fluctuations collapse into primordial black holes, a dark matter candidate and a possible source of gravitational waves. Stochastic inflation is a tool to compute the fluctuation statistics non-perturbatively, needed for accurate black hole predictions. I discuss recent progress in these computations, their numerical implementation and analytical approximations, and the implications for black hole abundance in single-field models of inflation.
