The Cosmological Impact of Intrinsic Alignment Model Choice for Cosmic Shear
Donnacha Kirk, Anais Rassat, Ole Host +1
We consider the effect of galaxy intrinsic alignments (IAs) on dark energy constraints from weak gravitational lensing. We summarise the latest version of the linear alignment mode…
Euclid Definition Study Report
R. Laureijs, J. Amiaux, S. Arduini +216
Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to…
Optimising cosmic shear surveys to measure modifications to gravity on cosmic scales
Donnacha Kirk, Istvan Laszlo, Sarah Bridle +1
We consider how upcoming photometric large scale structure surveys can be optimized to measure the properties of dark energy and possible cosmic scale modifications to General Rela…
Disentangling dark energy and cosmic tests of gravity from weak lensing systematics
Istvan Laszlo, Rachel Bean, Donnacha Kirk +1
We consider the impact of key astrophysical and measurement systematics on constraints on dark energy and modifications to gravity on cosmic scales. We focus on upcoming photometri…
