CCAPP Seminar - Simeon Bird (Carnegie Mellon) "Simulating Massive Neutrinos"
Abstract:Massive neutrinos make up a fraction of the dark matter, but due to their large thermal velocities, cluster significantly less than cold dark matter (CDM) on small scales. An accurate theoretical modelling of their effect on structure formation is required to fully exploit large-scale structure data. I will discuss different methods to add neutrinos to cosmological simulations, finishing with one which is accurate for current cosmological mass bounds and requires minimal extra computational cost. I will then talk about the impact of neutrino masses on cluster counts and perhaps the Lyman-alpha forest.
