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…
First Cosmology Results using Type Ia Supernovae from the Dark Energy Survey: Constraints on Cosmological Parameters
T. M. C. Abbott, S. Allam, P. Andersen +141
We present the first cosmological parameter constraints using measurements of type Ia supernovae (SNe Ia) from the Dark Energy Survey Supernova Program (DES-SN). The analysis uses…
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…
Dark Energy Survey Year 1 Results: Cross-correlation between DES Y1 galaxy weak lensing and SPT+Planck CMB weak lensing
Y. Omori, E. Baxter, C. Chang +137
We cross-correlate galaxy weak lensing measurements from the Dark Energy Survey (DES) year-one (Y1) data with a cosmic microwave background (CMB) weak lensing map derived from Sout…
Dark Energy Survey Year 1 Results: tomographic cross-correlations between DES galaxies and CMB lensing from SPT+Planck
Y. Omori, T. Giannantonio, A. Porredon +137
We measure the cross-correlation between redMaGiC galaxies selected from the Dark Energy Survey (DES) Year-1 data and gravitational lensing of the cosmic microwave background (CMB)…
