Abstract The Core Cosmology Library (CCL) provides routines to compute basic
cosmological observables to a high degree of accuracy, which have been verified with an …

Aims. We investigate the importance of lensing magnification for estimates of galaxy
clustering and its cross-correlation with shear for the photometric sample of Euclid. Using …

We investigate the accuracy of weak lensing simulations by comparing the results of five
independently developed lensing simulation codes run on the same input N-body …

Upcoming galaxy surveys will allow us to probe the growth of the cosmic large-scale
structure with improved sensitivity compared to current missions, and will also map larger …

We develop a fully non-invasive use of machine learning in order to enable open research
on Euclid-sized data sets. Our algorithm leaves complete control over theory and data …

Context. General relativistic effects on the clustering of matter in the Universe provide a
sensitive probe of cosmology and gravity theories that can be tested with the upcoming …

We derive and test an approximation for the angular power spectrum of galaxy number
counts in the flat sky limit. The standard density and redshift space distortion (RSD) terms in …

We combine measurements of galaxy velocities from galaxy surveys with measurements of
the Weyl potential from the Dark Energy Survey to test the consistency of general relativity at …
