Dark Energy Survey Year 3 Results: Point-Spread Function Modeling
M. Jarvis, G. M. Bernstein, A. Amon +79
We introduce a new software package for modeling the point-spread function (PSF) of astronomical images, called Piff (PSFs In the Full FOV), which we apply to the first three years…
Dark Energy Survey Year 1 Results: The Impact of Galaxy Neighbours on Weak Lensing Cosmology with im3shape
S. Samuroff, S. L. Bridle, J. Zuntz +68
We use a suite of simulated images based on Year 1 of the Dark Energy Survey to explore the impact of galaxy neighbours on shape measurement and shear cosmology. The hoopoe image s…
Galaxy bias from galaxy-galaxy lensing in the DES Science Verification Data
J. Prat, C. Sánchez, R. Miquel +68
We present a measurement of galaxy-galaxy lensing around a magnitude-limited () sample of galaxies from the Dark Energy Survey Science Verification (DES-SV) data. We…
Weak lensing by galaxy troughs in DES Science Verification data
D. Gruen, O. Friedrich, A. Amara +89
We measure the weak lensing shear around galaxy troughs, i.e. the radial alignment of background galaxies relative to underdensities in projections of the foreground galaxy field o…
Wide-Field Lensing Mass Maps from DES Science Verification Data
C. Chang, V. Vikram, B. Jain +81
We present a mass map reconstructed from weak gravitational lensing shear measurements over 139 sq. deg from the Dark Energy Survey (DES) Science Verification data. The mass map pr…
Wide-Field Lensing Mass Maps from DES Science Verification Data: Methodology and Detailed Analysis
V. Vikram, C. Chang, B. Jain +91
Weak gravitational lensing allows one to reconstruct the spatial distribution of the projected mass density across the sky. These "mass maps" provide a powerful tool for studying c…
