Cosmological constraining power of the redshifts, heights, and angular clustering of weak gravitational lensing peaks

Jeger C. Broxterman, Matthieu Schaller, Ian G. McCarthy +8

Weak gravitational lensing (WL) peaks probe non-Gaussian information of the large-scale distribution of matter that is not captured by two-point lensing statistics. We study the co…

cloelib: A Flexible Python Library for Computing Cosmological Observables in the Euclid Era

Marco Bonici, Guadalupe Cañas-Herrera, Pedro Carrilho +54

cloelib is a Python library developed to compute cosmological observables within the Cosmology Likelihood for Observables in Euclid (CLOE) ecosystem (cloe-org). As cosmology enters…

FLAMINGO: Baryonic effects on the weak lensing scattering transform

Mariia Marinichenko, Marcel P. van Daalen, Elena Sellentin +3

The scattering transform is a wavelet-based statistic capable of capturing non-Gaussian features in weak lensing (WL) convergence maps and has been proven to tighten cosmological p…

The resummation model in FLAMINGO: precisely predicting matter power suppression from observed halo baryon fractions

Marcel P. van Daalen, Ioannis Koutalios, Jeger C. Broxterman +4

In order to derive unbiased cosmological parameters from Stage-IV surveys, we need models that can predict the matter power spectrum for at least $k\,\lesssim\,10\,h\mathrm{\,Mpc^{…
