Dark Energy Survey year 1 results: Cosmological constraints from galaxy clustering and weak lensing
We present cosmological results from a combined analysis of galaxy clustering and weak gravitational lensing, using 1321  deg2 of griz imaging data from the first year of the Dark Energy Survey (DESExpand

Spin-induced Galaxy Alignments and Their Implications for Weak-Lensing Measurements
Large-scale correlations in the orientations of galaxies can result from alignments in their angular momentum vectors. These alignments arise from the tidal torques exerted on neighboringExpand

Discriminating weak lensing from intrinsic spin correlations using the curl-gradient decomposition
The distortion field defined by the ellipticities of galaxy shapes as projected on the sky can be uniquely decomposed into a gradient and a curl component. If the observed ellipticities are inducedExpand

Combined analysis of the integrated Sachs-Wolfe effect and cosmological implications
We present a global measurement of the integrated Sachs-Wolfe (ISW) effect obtained by cross correlating all relevant large-scale galaxy data sets with the cosmic microwave background radiation mapExpand

The significance of the integrated Sachs–Wolfe effect revisited
We revisit the state of the integrated Sachs–Wolfe (ISW) effect measurements in light of newly available data and address criticisms about the measurements which have recently been raised. We updateExpand

Dynamical dark energy in light of the latest observations
A flat Friedmann–Robertson–Walker universe dominated by a cosmological constant (Λ) and cold dark matter (CDM) has been the working model preferred by cosmologists since the discovery of cosmicExpand

Ameliorating systematic uncertainties in the angular clustering of galaxies: a study using the SDSS-III
We investigate the effects of potential sources of systematic error on the angular and photometric redshift, zphot, distributions of a sample of redshift 0.4 0.5, the magnitude of the corrections weExpand

Exactly azimuthal pixelizations of the sky
We investigate various pixelizations of the sky which allow for fast spherical transforms, for implementation in full sky CMB experiments such as Planck and MAP. We study the effect of varying pixelExpand

A correlation between the cosmic microwave background and large-scale structure in the Universe
Observations of distant supernovae and the fluctuations in the cosmic microwave background (CMB) indicate that the expansion of the Universe may be accelerating under the action of a ‘cosmologicalExpand

High redshift detection of the integrated Sachs-Wolfe effect
We present evidence of a large angle correlation between the cosmic microwave background measured by WMAP and a catalog of photometrically detected quasars from the SDSS. The observed crossExpand
