Combining spectroscopic and photometric surveys using angular cross-correlations I: Algorithm and modelling
Martin Eriksen, Enrique Gaztanaga
Weak lensing (WL) clustering is studied using 2D (angular) coordinates, while redshift space distortions (RSD) and baryon acoustic oscillations (BAO) use 3D coordinates, which requ…
Combining Spectroscopic and Photometric Surveys: Same or different sky?
Martin Eriksen, Enrique Gaztanaga
This article looks at the combined constraints from a photometric and spectroscopic survey. These surveys will measure cosmology using weak lensing (WL), galaxy clustering, baryon…
A Measurement of Gravitational Lensing of the Cosmic Microwave Background by Galaxy Clusters Using Data from the South Pole Telescope
E. J. Baxter, R. Keisler, S. Dodelson +72
Clusters of galaxies are expected to gravitationally lens the cosmic microwave background (CMB) and thereby generate a distinct signal in the CMB on arcminute scales. Measurements…
Optical & Sunyaev-Zel'dovich Observations of a New Sample of Distant Rich Galaxy Clusters in the ROSAT All Sky Survey
A. Buddendiek, T. Schrabback, C. H. Greer +15
Finding a sample of the most massive clusters with redshifts can provide an interesting consistency check of the cold dark matter (CDM) model. Here we present result…
Evidence for the inside-out growth of the stellar mass distribution in galaxy clusters since z~1
Remco F. J. van der Burg, Henk Hoekstra, Adam Muzzin +3
We study the radial number density and stellar mass density distributions of satellite galaxies in a sample of 60 massive clusters at 0.04<z<0.26 selected from the Multi-Epoch Near…
The return of the merging galaxy subclusters of El Gordo?
Karen Y. Ng, William A. Dawson, D. Wittman +4
Merging galaxy clusters with radio relics provide rare insights to the merger dynamics as the relics are created by the violent merger process. We demonstrate one of the first uses…
