3D cosmic shear: numerical challenges, 3D lensing random fields generation and Minkowski Functionals for cosmological inference
A. Spurio Mancini, P. L. Taylor, R. Reischke +5
Cosmic shear - the weak gravitational lensing effect generated by fluctuations of the gravitational tidal fields of the large-scale structure - is one of the most promising tools f…
Investigating scalar-tensor-gravity with statistics of the cosmic large-scale structure
Robert Reischke, Alessio Spurio Mancini, Björn Malte Schäfer +1
Future observations of the large-scale structure have the potential to investigate cosmological models with a high degree of complexity, including the properties of gravity on larg…
Imitating intrinsic alignments: A bias to the CMB lensing-galaxy shape cross-correlation power spectrum induced by the large-scale structure bispectrum
Philipp M. Merkel, Bjoern Malte Schaefer
Cross-correlating the lensing signals of galaxies and comic microwave background (CMB) fluctuations is expected to provide valuable cosmological information. In particular it may h…
Parameter constraints from weak lensing tomography of galaxy shapes and cosmic microwave background fluctuations
Philipp M. Merkel, Bjoern Malte Schaefer
Recently, it has been shown that cross-correlating CMB lensing and 3D cosmic shear allows to considerably tighten cosmological parameter constraints. We investigate whether similar…
The cross-correlation between 3d cosmic shear and the integrated Sachs-Wolfe effect
Britta Zieser, Philipp M. Merkel
We present the first calculation of the cross-correlation between three-dimensional cosmic shear and the integrated Sachs-Wolfe (iSW) effect. Both signals are combined in a single…
Angular spectra of the intrinsic galaxy ellipticity field, their observability and their impact on lensing in tomographic surveys
Bjoern Malte Schaefer, Philipp M. Merkel
Subject of this paper are intrinsic ellipticity correlations between galaxies, their statistical properties, their observability with future surveys and their interference with wea…
