Baryonic effects for weak lensing. Part II. Combination with X-ray data and extended cosmologies
Aurel Schneider, Alexandre Refregier, Sebastian Grandis +6
An accurate modelling of baryonic feedback effects is required to exploit the full potential of future weak-lensing surveys such as Euclid or LSST. In this second paper in a series…
Baryonic effects for weak lensing. Part I. Power spectrum and covariance matrix
Aurel Schneider, Nicola Stoira, Alexandre Refregier +4
Baryonic feedback effects lead to a suppression of the weak lensing angular power spectrum on small scales. The poorly constrained shape and amplitude of this suppression is an imp…
Bifurcation in the history of Uranus and Neptune: the role of giant impacts
Christian Reinhardt, Alice Chau, Joachim Stadel +1
Despite many similarities, there are significant observed differences between Uranus and Neptune: while Uranus is tilted and has a regular set of satellites, suggesting their accre…
Dark energy perturbations in -body simulations
Jeppe Dakin, Steen Hannestad, Thomas Tram +2
We present -body simulations which are fully compatible with general relativity, with dark energy consistently included at both the background and perturbation level. We test ou…
Primordial Earth mantle heterogeneity caused by the Moon-forming giant impact
Hongping Deng, Maxim D. Ballmer, Christian Reinhardt +4
The giant impact hypothesis for Moon formation successfully explains the dynamic properties of the Earth-Moon system but remains challenged by the similarity of isotopic fingerprin…
Estimating the Integrated Bispectrum from Weak Lensing Maps
D. Munshi, J. D. McEwen, T. Kitching +3
We use a recently introduced statistic called {\em Integrated Bispectrum} (IB) to probe the gravity-induced non-Gaussianity at the level of the bispectrum from weak lensing converg…
