Marco Gatti and Pauline Vielzeuf - Clustering-redshift methodology in Dark Energy Survey Year 1 analysis

Wednesday Oct 4, 2017, 1:00 PM → 2:00 PM Europe/Madrid

Seminar (IFAE)

Michael Leyton (IFAE), Stefano Terzo (IFAE)

Clustering-redshift is a recently developed tool to reconstruct galaxy distributions in redshift. In the context of DES Y1, it has been used to calibrate redshift distributions obtained from photo-z algorithms of the weak lensing (WL) source galaxies. I will introduce the method and present how it has been tested in simulations and then applied to data. The calibration procedure on data has also been successfully cross-checked with two additional independent tests.
