Data Updates

I am now incorporating the DES redMaGiC galaxy catalogue of luminous red galaxies. The number density maps will be made up of CMASS and redMaGiC galaxies. Figure 1 shows a ~200 Mpc slice at z~.55 with CMASS galaxies plotted in blue and redMaGiC in gray. The redMaPPer clusters which will be stacked are plotted in larger red circles. As expected, the clusters trace the redMaGiC galaxy distribution because the two samples are run with the same algorithm.

I also got the ACT SZ cluster catalog from Mat, so that I can incorporate clusters in the BOSS region. I need to learn more about this catalog, since many of the clusters have redshifts given for them but I don't know this is done with SZ / how the errors work.

Data Stacks

The following plots are various versions of stacks on cluster locations in the number density map with different versions of orientation on various smoothing scales. Some also have eccentricity cuts.

Sims

Trying eccentricity cuts. Start with lambda > 10 clusters (from Redmapper lambda-halo mass relation), 200 Mpc slice ~ z=0.55. Hessian orientation on 30 arcminutes of the full number density map from Peak Patch.

2258 clusters, no e cut.

1075 clusters, e > 500 at 30a.

735 clusters, e > 700 at 30a.

596 clusters, e > 800 at 30a.

596 clusters, e > 800, X-UP at 30a.
