Galaxy clusters morphology with Zernike polynomials: the first application on Compton parameter maps
Valentina Capalbo, Marco De Petris, Weiguang Cui +3
The study of the morphology of 2D projected maps of galaxy clusters is a suitable approach to infer, from real data, the dynamical state of those systems. We recently developed a n…
Homology reveals significant anisotropy in the cosmic microwave background
Pratyush Pranav, Thomas Buchert
We test the tenet of statistical isotropy of the standard cosmological model via a homology analysis of the cosmic microwave background temperature maps. Examining small sectors of…
Euclid: Constraints on f(R) cosmologies from the spectroscopic and photometric primary probes
S. Casas, V. F. Cardone, D. Sapone +126
will provide a powerful compilation of data including spectroscopic redshifts, the angular clustering of galaxies, weak lensing cosmic shear, and the cross-correl…
Euclid Preparation. XXVIII. Forecasts for ten different higher-order weak lensing statistics
Euclid Collaboration, V. Ajani, M. Baldi +211
Recent cosmic shear studies have shown that higher-order statistics (HOS) developed by independent teams now outperform standard two-point estimators in terms of statistical precis…
