SUMMARY:SPEAKER - Nick Kokron (Stanford University) - TITLE:  Pen-and-Paper Meets Supercomputing: Building Accurate Models for Cosmological Surveys
DESCRIPTION:LOCATION: IN-PERSON – Sessler Conference Room Building 50A-5132 \nTITLE: Pen-and-Paper Meets Supercomputing: Building Accurate Models for Cosmological Surveys \nABSTRACT: Stage-IV cosmological surveys are poised to revolutionize our understanding of the Universe. The vast data sets collected by surveys like DESI\, Rubin and CMB-S4 will be orders of magnitude more powerful than their precursors from the last decade\, and will significantly sharpen our understanding of unknown properties of the Universe. These include the properties of dark energy\, the masses of neutrinos and the fundamental nature of the primordial fluctuations in the early Universe. However the statistical uncertainties of upcoming observations are so small that models for the statistics we measure are not yet accurate enough to analyze their whole datasets. I will introduce a program of research dedicated to addressing the challenge of accurately modelling these data and making our cosmological surveys the most powerful they can be. This program is underpinned by a fruitful marriage of traditionally disparate techniques — supercomputer simulations and pen-and-paper calculations — to describe the growth and evolution of large-scale structure in the Universe. I will show that their combination is more powerful than the sum of its parts\, and will play a key role in extracting the most amount of information from DESI and its cross-correlations with weak and CMB lensing surveys in the coming future. \nZOOM Information –  \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585
