Cosmology with cosmic shear observations: a review

M Kilbinger - Reports on Progress in Physics, 2015 - iopscience.iop.org
Cosmic shear is the distortion of images of distant galaxies due to weak gravitational lensing
by the large-scale structure in the Universe. Such images are coherently deformed by the …

Galaxy alignments: Observations and impact on cosmology

D Kirk, ML Brown, H Hoekstra, B Joachimi… - Space Science …, 2015 - Springer
Galaxy shapes are not randomly oriented, rather they are statistically aligned in a way that
can depend on formation environment, history and galaxy type. Studying the alignment of …

We present cosmological results from a combined analysis of galaxy clustering and weak
gravitational lensing, using 1321 deg 2 of griz imaging data from the first year of the Dark …

Dark Energy Survey Year 1 results: Cosmological constraints from cosmic shear

MA Troxel, N MacCrann, J Zuntz, TF Eifler, E Krause… - Physical Review D, 2018 - APS
We use 26× 10 6 galaxies from the Dark Energy Survey (DES) Year 1 shape catalogs over

We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters
selected from the Dark Energy Survey (DES) Year 1 dataset. Our analysis uses the same …

Practical weak-lensing shear measurement with metacalibration

ES Sheldon, EM Huff - The Astrophysical Journal, 2017 - iopscience.iop.org
Metacalibration is a recently introduced method to accurately measure weak gravitational
lensing shear using only the available imaging data, without need for prior information about …

Dark Energy Survey Year 1 results: weak lensing shape catalogues

J Zuntz, E Sheldon, S Samuroff… - Monthly Notices of …, 2018 - academic.oup.com
We present two galaxy shape catalogues from the Dark Energy Survey Year 1 data set,

Dark Energy Survey Year 1 results: weak lensing mass calibration of redMaPPer galaxy clusters

T McClintock, TN Varga, D Gruen… - Monthly Notices of …, 2019 - academic.oup.com
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 into …
