Beyond Limber: Efficient computation of angular power spectra for galaxy clustering and weak lensing
Xiao Fang, Elisabeth Krause, Tim Eifler +1
Angular two-point statistics of large-scale structure observables are important cosmological probes. To reach the high accuracy required by the statistical precision of future surv…
Mitigating Shear-dependent Object Detection Biases with Metacalibration
Erin S. Sheldon, Matthew R. Becker, Niall MacCrann +1
Metacalibration is a new technique for measuring weak gravitational lensing shear that is unbiased for isolated galaxy images. In this work we test metacalibration with overlapping…
STRIDES: a 3.9 per cent measurement of the Hubble constant from the strong lens system DES J0408-5354
A. J. Shajib, S. Birrer, T. Treu +88
We present a blind time-delay cosmographic analysis for the lens system DES J04085354. This system is extraordinary for the presence of two sets of multiple images at different…
The SPTpol Extended Cluster Survey
L. E. Bleem, S. Bocquet, B. Stalder +135
We describe the observations and resultant galaxy cluster catalog from the 2770 deg SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the Sunyaev-Zel'dovich…
Dark Energy Survey Year 1 results: The relationship between mass and light around cosmic voids
Y. Fang, N. Hamaus, B. Jain +74
What are the mass and galaxy profiles of cosmic voids? In this paper we use two methods to extract voids in the Dark Energy Survey (DES) Year 1 redMaGiC galaxy sample to address th…
Detection of cross-correlation between gravitational lensing and gamma rays
S. Ammazzalorso, D. Gruen, M. Regis +75
In recent years, many gamma-ray sources have been identified, yet the unresolved component hosts valuable information on the faintest emission. In order to extract it, a cross-corr…
Producing a BOSS-CMASS sample with DES imaging
S. Lee, E. M. Huff, A. J. Ross +57
We present a sample of galaxies with the Dark Energy Survey (DES) photometry that replicates the properties of the BOSS CMASS sample. The CMASS galaxy sample has been well characte…
Controlling and leveraging small-scale information in tomographic galaxy-galaxy lensing
Niall MacCrann, Jonathan Blazek, Bhuvnesh Jain +1
The tangential shear signal receives contributions from physical scales in the galaxy-matter correlation function well below the transverse scale at which it is measured. Since sma…
The Buzzard Flock: Dark Energy Survey Synthetic Sky Catalogs
Joseph DeRose, Risa H. Wechsler, Matthew R. Becker +52
We present a suite of 18 synthetic sky catalogs designed to support science analysis of galaxies in the Dark Energy Survey Year 1 (DES Y1) data. For each catalog, we use a computat…
