Massive Neutrinos in Cosmology
Presented by Simeon Bird
University of California, Riverside

Monday, May 21, 2018
12:00 noon in 169-336

Measuring the neutrino mass is something cosmologists hope to do within the next decade. However, the best constraints come from small scales, requiring N-body simulations. I will talk about a new efficient and accurate technique to add neutrinos to N-body simulations, and a recent simulation suite performed with this technique. Small scales also pose the spectre of confusion with baryonic effects; I will talk about the BAHAMAS project, where we used calibrated simulations of AGN to produce predictions for Planck tSZ and other cluster statistics.
