Towards emulating cosmic shear data: Revisiting the calibration of the shear measurements for the Kilo-Degree Survey
Arun Kannawadi, Henk Hoekstra, Lance Miller +9
Exploiting the full statistical power of future cosmic shear surveys will necessitate improvements to the accuracy with which the gravitational lensing signal is measured. We prese…
The dependence of intrinsic alignment of galaxies on wavelength using KiDS and GAMA
Christos Georgiou, Harry Johnston, Henk Hoekstra +6
The outer regions of galaxies are more susceptible to the tidal interactions that lead to intrinsic alignments of galaxies. The resulting alignment signal may therefore depend on t…
A Bayesian quantification of consistency in correlated datasets
Fabian Köhlinger, Benjamin Joachimi, Marika Asgari +3
We present three tiers of Bayesian consistency tests for the general case of datasets. Building on duplicates of the model parameters assigned to each dataset, these t…
Unveiling Galaxy Bias via the Halo Model, KiDS and GAMA
Andrej Dvornik, Konrad Kuijken, Henk Hoekstra +11
We measure the projected galaxy clustering and galaxy-galaxy lensing signals using the Galaxy And Mass Assembly (GAMA) survey and Kilo-Degree Survey (KiDS) to study galaxy bias. We…
Multi-wavelength scaling relations in galaxy groups: a detailed comparison of GAMA and KiDS observations to BAHAMAS simulations
Arthur Jakobs, Massimo Viola, Ian McCarthy +18
We study the scaling relations between the baryonic content and total mass of groups of galaxies, as these systems provide a unique way to examine the role of non-gravitational pro…
KiDS-450 + 2dFLenS: Cosmological parameter constraints from weak gravitational lensing tomography and overlapping redshift-space galaxy clustering
Shahab Joudaki, Chris Blake, Andrew Johnson +19
We perform a combined analysis of cosmic shear tomography, galaxy-galaxy lensing tomography, and redshift-space multipole power spectra (monopole and quadrupole) using 450 deg…
