The skewed weak lensing likelihood: why biases arise, despite data and theory being sound
Elena Sellentin, Catherine Heymans, Joachim Harnois-Déraps
We derive the essentials of the skewed weak lensing likelihood via a simple Hierarchical Model. Our likelihood passes four objective and cosmology-independent tests which a standar…
KiDS-450: Cosmological Constraints from Weak Lensing Peak Statistics-I: Inference from Analytical Prediction of High Signal-to-Noise Ratio Convergence Peaks
HuanYuan Shan, Xiangkun Liu, Hendrik Hildebrandt +19
This paper is the first of a series of papers constraining cosmological parameters with weak lensing peak statistics using of imaging data from the Kilo Degree…
KiDS-450: Cosmological Constraints from Weak Lensing Peak Statistics - II: Inference from Shear Peaks using N-body Simulations
Nicolas Martinet, Peter Schneider, Hendrik Hildebrandt +12
We study the statistics of peaks in a weak lensing reconstructed mass map of the first 450 square degrees of the Kilo Degree Survey. The map is computed with aperture masses direct…
KiDS+GAMA: Cosmology constraints from a joint analysis of cosmic shear, galaxy-galaxy lensing and angular clustering
Edo van Uitert, Benjamin Joachimi, Shahab Joudaki +19
We present cosmological parameter constraints from a joint analysis of three cosmological probes: the tomographic cosmic shear signal in 450 deg of data from the Kilo Deg…
KiDS-450: Tomographic Cross-Correlation of Galaxy Shear with {\it Planck} Lensing
Joachim Harnois-Déraps, Tilman Tröster, Nora Elisa Chisari +14
We present the tomographic cross-correlation between galaxy lensing measured in the Kilo Degree Survey (KiDS-450) with overlapping lensing measurements of the cosmic microwave back…
Precision calculations of the cosmic shear power spectrum projection
Martin Kilbinger, Catherine Heymans, Marika Asgari +9
We compute the spherical-sky weak-lensing power spectrum of the shear and convergence. We discuss various approximations, such as flat-sky, and first- and second- order Limber equa…
