Theoretical Cosmology meetings
To actively encourage the field of theoretical cosmology and to set an informal stage for the exchange of ideas, the Dutch theoretical cosmology community organizes Friday afternoon meetings approximately 6 times a year — usually on the first Friday of the month. The meetings typically start in the afternoon with a main speaker, followed by a short break to continue with another seminar or journal club discussion on some topic of current interest. We end the afternoon with drinks. The supporting institutes in Leiden, Amsterdam, Groningen, Utrecht where recently joined by the strings and cosmology group in Leuven and take turns in hosting the event.

12:30-13:30 Program lunch [only for FOM cosmology program leaders to schedule next year/workshops/NWA update/Core+ update] in room C4.250

Title: Large Field Inflation, the Weak Gravity Conjecture and Gravitational Instantons
Abstract: The recent theoretical interest in large-field inflation is related in part to potential future observations, e.g. through primordial gravity waves, and in part to the structural simplicity of the corresponding models. I will concetrate on the possible fundamental obstructions to realising such inflationary scenarios, both in string theory and in quantum gravity in general. The focus will in particular be on the recent scientific debate in the context of the Weak Gravity Conjecture and Gravitational Instantons, which will both be explained in simple terms.
15:30-16:30 Talk by Guido D’Amico (CERN) in room D1.116
Title: Consistency and predictivity of the EFT of LSS
Abstract: I discuss the Effective Field Theory of Large Scale Structure prescription to one loop, with emphasis on the robustness of the EFT parameters and the resulting regime of validity when compared to high-resolution simulations. In particular, I will outline the consistency between propagator and power spectrum, fit the redshift dependence of the EFT parameters and discuss the bispectrum.
16:30 Drinks in ‘Academisch Kwartier’
