LBNL-2016: Cross Correlations

From CMB-S4 wiki
Jump to: navigation, search

The purpose of this session is to come up with a list of forecasts that we should do using CMB and auxiliary datasets, such as LSST, DESI, etc. These will be incorporated into sections of the Science Book and could help with the question of siting. Note: there is a lensing foreground session at 9:45 that some may want to attend, so let's discuss CMB kappa first.

Those agreeing to present should not prepare full-blown talks, but rather a slide or two with some ideas that will foment discussion.

Question: is someone going to provide timelines and coverage for the auxiliary datasets?

DESI: 2019-24; 14k sq deg; 30M spectroscopic objects

LSST: 2022-32: 20k sq deg; photo-z good to ~0.03(1+z); 4B galaxies out to z~2-3

Euclid: 2021?: 15k sq deg, not as deep as LSST

WFIRST: 2024?-2028: 2.5k sq deg, as deep as LSST, with spectroscopy

Schedule: start 10 min after "charge to parallel sessions" ends

Spectroscopic samples vs photometric?
