Lensing without mixing: Probing Baryonic Acoustic Oscillations and other scale-dependent features in cosmic shear surveys
David Touzeau, Alexandre Barthelemy, Francis Bernardeau
Weak-gravitational lensing tends to wash out scale- and time-dependent features of the clustering of matter, such as the baryonic acoustic oscillations which appear in the form of…
Euclid preparation. LXXXV. Toward a DR1 application of higher-order weak lensing statistics
Euclid Collaboration, S. Vinciguerra, F. Bouchè +284
This is the second paper in the HOWLS (higher-order weak lensing statistics) series exploring the usage of non-Gaussian statistics for cosmology inference within Euclid. With respe…
Clustering of the extreme: A theoretical description of weak lensing critical points power spectra in the mildly nonlinear regime
Zhengyangguang Gong, Alexandre Barthelemy, Sandrine Codis
In cosmic web analysis, complementary to traditional cosmological probes, the extrema (e.g. peaks and voids) two-point correlation functions (2PCFs) are of particular interest for…
A theoretical view of the T-web statistical description of the cosmic web
Emma Ayçoberry, Alexandre Barthelemy, Sandrine Codis
The classification of the cosmic web into different environments is both a tool to study in more detail the formation of halos and galaxies via the link between their properties an…
