Rapid Simulations of Halo and Subhalo Clustering

Pascale Berner, Alexandre Refregier, Raphael Sgier +3

The analysis of cosmological galaxy surveys requires realistic simulations for their interpretation. Forward modelling is a powerful method to simulate galaxy clustering without th…

Dark Energy Survey Year 3 results: Cosmology with peaks using an emulator approach

D. Zürcher, J. Fluri, R. Sgier +119

We constrain the matter density $Ω_{m}$ and the amplitude of density fluctuations $σ_{8}$ within the $Λ$ CDM cosmological model with shear peak statistics and angular converg…

Combined $13 \times 2$ -point analysis of the Cosmic Microwave Background and Large-Scale Structure: implications for the $S_{8}$ -tension and neutrino mass constraints

Raphael Sgier, Christiane Lorenz, Alexandre Refregier +3

We present cosmological constraints for the flat $Λ$ CDM model, including the sum of neutrino masses, by performing a multi-probe analysis of a total of 13 tomographic auto- and cro…
