The Wendelstein Weak Lensing (WWL) pathfinder: Accurate weak lensing masses for Planck clusters
Romy Louise Rehmann, Daniel Gruen, Stella Seitz +8
We present results from the Wendelstein Weak Lensing (WWL) pathfinder project, in which we have observed three intermediate redshift Planck clusters of galaxies with the new 30'$\t…
Weak lensing by galaxy troughs in DES Science Verification data
D. Gruen, O. Friedrich, A. Amara +89
We measure the weak lensing shear around galaxy troughs, i.e. the radial alignment of background galaxies relative to underdensities in projections of the foreground galaxy field o…
Environment-based selection effects of Planck clusters
Ralf Kosyra, Daniel Gruen, Stella Seitz +5
We investigate whether the large scale structure environment of galaxy clusters imprints a selection bias on Sunyaev Zel'dovich (SZ) catalogs. Such a selection effect might be caus…
Cosmic variance of the galaxy cluster weak lensing signal
D. Gruen, S. Seitz, M. R. Becker +2
Intrinsic variations of the projected density profiles of clusters of galaxies at fixed mass are a source of uncertainty for cluster weak lensing. We present a semi-analytical mode…
Combining clustering and abundances of galaxy clusters to test cosmology and primordial non-Gaussianity
Annalisa Mana, Tommaso Giannantonio, Jochen Weller +3
We present the clustering of galaxy clusters as a useful addition to the common set of cosmological observables. The clustering of clusters probes the large-scale structure of the…
