Intrinsic galaxy shapes and alignments II: Modelling the intrinsic alignment contamination of weak lensing surveys
B. Joachimi, E. Semboloni, S. Hilbert +4
Intrinsic galaxy alignments constitute the major astrophysical systematic of forthcoming weak gravitational lensing surveys but also yield unique insights into galaxy formation and…
Relations between three-point configuration space shear and convergence statistics
X. Shi, P. Schneider, B. Joachimi
With the growing interest in and ability of using weak lensing studies to probe the non-Gaussian properties of the matter density field, there is an increasing need for the study o…
Controlling intrinsic alignments in weak lensing statistics: The nulling and boosting techniques
B. Joachimi, P. Schneider
The intrinsic alignment of galaxies constitutes the major astrophysical source of systematic errors in surveys of weak gravitational lensing by the large-scale structure. We discus…
Intrinsic alignment boosting: Direct measurement of intrinsic alignments in cosmic shear data
B. Joachimi, P. Schneider
Intrinsic alignments constitute the major astrophysical systematic for cosmological weak lensing surveys. We present a purely geometrical method with which one can study gravitatio…
Controlling intrinsic-shear alignment in three-point weak lensing statistics
X. Shi, B. Joachimi, P. Schneider
Three-point weak lensing statistics provide cosmic information complementary to that of two-point statistics. However, both statistics suffer from intrinsic-shear alignment, which…
The removal of shear-ellipticity correlations from the cosmic shear signal: Influence of photometric redshift errors on the nulling technique
B. Joachimi, P. Schneider
Cosmic shear is regarded one of the most powerful probes to reveal the properties of dark matter and dark energy. To fully utilize its potential, one has to be able to control syst…
