Dark Energy Survey Year 1 results: Validation of weak lensing cluster member contamination estimates from P(z) decomposition
T. N. Varga, J. DeRose, D. Gruen +68
Weak lensing source galaxy catalogs used in estimating the masses of galaxy clusters can be heavily contaminated by cluster members, prohibiting accurate mass calibration. In this…
Measurement of the Splashback Feature around SZ-selected Galaxy Clusters with DES, SPT and ACT
T. Shin, S. Adhikari, E. J. Baxter +107
We present a detection of the splashback feature around galaxy clusters selected using their Sunyaev-Zel'dovich (SZ) signal. Recent measurements of the splashback feature around op…
Dark Energy Survey Year 1 Results: Methods for Cluster Cosmology and Application to the SDSS
M. Costanzi, E. Rozo, M. Simet +83
We perform the first blind analysis of cluster abundance data. Specifically, we derive cosmological constraints from the abundance and weak-lensing signal of \redmapper\ clusters o…
Mass Calibration of Optically Selected DES clusters using a Measurement of CMB-Cluster Lensing with SPTpol Data
S. Raghunathan, S. Patil, E. Baxter +129
We use cosmic microwave background (CMB) temperature maps from the 500 deg SPTpol survey to measure the stacked lensing convergence of galaxy clusters from the Dark Energy Su…
Modeling projection effects in optically-selected cluster catalogues
M. Costanzi, E. Rozo, E. S. Rykoff +13
The cosmological utility of galaxy cluster catalogues is primarily limited by our ability to calibrate the relation between halo mass and observable mass proxies such as cluster ri…
Dark Energy Survey Year 1 Results: Weak Lensing Mass Calibration of redMaPPer Galaxy Clusters
T. McClintock, T. N. Varga, D. Gruen +99
We constrain the mass--richness scaling relation of redMaPPer galaxy clusters identified in the Dark Energy Survey Year 1 data using weak gravitational lensing. We split clusters i…
The Aemulus Project III: Emulation of the Galaxy Correlation Function
Zhongxu Zhai, Jeremy L. Tinker, Matthew R. Becker +6
Using the N-body simulations of the AEMULUS Project, we construct an emulator for the non-linear clustering of galaxies in real and redshift space. We construct our model of galaxy…
The Aemulus Project II: Emulating the Halo Mass Function
Thomas McClintock, Eduardo Rozo, Matthew R. Becker +6
Existing models for the dependence of the halo mass function on cosmological parameters will become a limiting source of systematic uncertainty for cluster cosmology in the near fu…
The Aemulus Project I: Numerical Simulations for Precision Cosmology
Joseph DeRose, Risa H. Wechsler, Jeremy L. Tinker +6
The rapidly growing statistical precision of galaxy surveys has lead to a need for ever-more precise predictions of the observables used to constrain cosmological and galaxy format…
