LFI on neutrino mass from cosmology
We have 100 cosmological models (x 10,000 map realizations each) and computed higher-order statistics (power spectrum, bispectrum, PDF, peak counts) on all of them. We would like help to apply LFI on them.
Contacts: Jia Liu Participants: Jia Liu, Will Coulton
Goals and deliverable
Get a posterior using an (or multiple!) LFI method(s), and compare that with our (already done) Gaussian-likelihood result.
Resources needed
We will use statistics computed already from the MassiveNuS simulation: http://columbialensing.org/#massivenus
