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…
Matter power spectrum reconstruction with KiDS-Legacy: Improved internal CDM consistency and preference for strong baryonic feedback
Jeger C. Broxterman, Patrick Simon, Lucas Porth +14
Direct measurements of the matter power spectrum, , provide a powerful tool to investigate observed tensions between models of structure growth while also testin…
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^{…
Euclid: An emulator for baryonic effects on the matter bispectrum
P. A. Burger, G. Aricò, L. Linke +153
Understanding the impact of baryonic processes such as star formation and active galactic nuclei (AGN) feedback on matter clustering is crucial to ensure precise and unbiased cosmo…
The FLAMINGO project: cosmology with the redshift dependence of weak gravitational lensing peaks
Jeger C. Broxterman, Matthieu Schaller, Henk Hoekstra +5
Weak gravitational lensing (WL) convergence peaks contain valuable cosmological information in the regime of non-linear collapse. Using the FLAMINGO suite of cosmological hydrodyna…
