Astrophysics Luncheon Seminar Massive Neutrinos in Cosmology Presented by Simeon Bird University of California, Riverside Monday, May 21, 2018 12:00 noon in 169-336 and on Webex Abstract 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. JPL Contact: Melanie Simet About the Speaker Dr. Simeon Bird recently joined the faculty at the University of California, Riverside. Previously, he was a postdoc at Johns Hopkins University, Carnegie Mellon University and Institute for Advanced Study, Princeton, New Jersey. He earned his PhD at the University of Cambridge, UK. He is interested in cosmology, structure formation simulations, absorption lines, and machine learning.   Site Manager: Webmaster: CL 08-3220
