About this award
The National Aeronautics and Space Administration (NASA) awarded a $309,450.00 grant for research to the University of Arizona, doing business as the Arizona Board of Regents. This new grant will fund a joint analysis of data from the Planck mission and the Dark Energy Survey, using an approximate Bayesian framework to properly account for correlations and shared systematic errors between the two datasets. The research effort will also integrate cosmic microwave background simulation software into the PI and co-I's existing analysis framework, enabling a combined analysis of the Planck and Dark Energy Survey data to provide significantly stronger constraints on cosmological models, including extensions to the standard Lambda-CDM cosmological model. This grant does not have a set-aside designation.
Description
This proposed research is a new, joint analysis of planck and dark energy survey (DES) data in an approximate bayesian framework that can properly take into account correlations and shared systematics between probes. The first part of the proposal is a reanalysis of planck data performed in a basis more directly comparable to large scale structure (LSS) data and without the same assumptions about the shape of the likelihood functions of cosmic microwave background (CMB) power spectra. The second part is an integration of CMB simulation software into cosmolike, the PI and CO-i s bayesian analysis framework, and a joint analysis of planck and DES data using that software. This effort will also involve the estimation of correlated systematics between the CMB and LSS data and IT will lead to significantly stronger constraints on cosmological models, including extensions to the lambda-cold dark matter (lcdm) cosmological model.
