Lensing is Too Low 2019


October 7 – 11, 2019

Organized by Klaus Honscheid

The Center for Cosmology and AstroParticle Physics (CCAPP) at The Ohio State University (OSU) is hosting the workshop in Columbus, Ohio at the Physics Research Building - Room M2015. 

Several groups have observed the Delta Sigma measurements at small scales are low when compared to the signal predicted from BOSS CMASS clustering and a number of simulations.The proposed workshop brings together a group of researchers from DES to repeat this measurement using the using the newly-defined DES CMASS analogue (DMASS) sample (Lee et al, MNRAS) as a lens sample and the DES Y1 metacalibration sample as the shape sample. This data vector will be compared to the lensing signal predicted from the CMASS clustering + a number of simulations as in Leauthaud et al 2017 (Lensing is Low).
