Euclid preparation XXXVI. Modelling the weak lensing angular power spectrum
Frédéric Courbin, Georges Meylan, Gianluca Castignani, Austin Chandler Peel, Maurizio Martinelli, Yi Wang, Richard Massey, Fabio Finelli, Marcello Farina
This work considers which higher order modeling e ffects on the cosmic shear angular power spectra must be taken into account for Euclid. We identified the relevant terms and quantified their individual and cumulative impact on the cosmological parameter i ...
Edp Sciences S A2024Swift : a modern highly parallel gravity and smoothed particle hydrodynamics solver for astrophysical and cosmological applications
Yves Revaz, Loïc Hausammann, Matthieu Schaller, Mladen Ivkovic, Zhen Xiang
Numerical simulations have become one of the key tools used by theorists in all the fields of astrophysics and cosmology. The development of modern tools that target the largest existing computing systems and exploit state-of-the-art numerical methods and ...
2024Euclid: Validation of the MontePython forecasting tools
Frédéric Courbin, Georges Meylan, Jean-Luc Starck, Maurizio Martinelli, Julien Lesgourgues, Slobodan Ilic, Yi Wang, Richard Massey
Context. The Euclid mission of the European Space Agency will perform a survey of weak lensing cosmic shear and galaxy clustering in order to constrain cosmological models and fundamental physics. Aims. We expand and adjust the mock Euclid likelihoods of t ...
Les Ulis Cedex A2024Cosmic void exclusion models and their impact on the distance scale measurements from large-scale structure
Jean-Paul Richard Kneib, Andrei Variu, Daniel Felipe Forero Sanchez, Cheng Zhao, Amélie Tamone
Baryonic Acoustic Oscillations (BAOs) studies based on the clustering of voids and matter tracers provide important constraints on cosmological parameters related to the expansion of the Universe. However, modelling the void exclusion effect is an importan ...
OXFORD UNIV PRESS2023Fast correlation function calculator A high-performance pair-counting toolkit
Context. A novel high-performance exact pair-counting toolkit called fast correlation function calculator (FCFC) is presented.Aims. With the rapid growth of modern cosmological datasets, the evaluation of correlation functions with observational and simula ...
EDP SCIENCES S A2023Teaching machines how to find strongly lensed galaxies in cosmological sky surveys.
Analyzing gravitationally lensed objects enables a wide range of physical and cosmological applications, such as probing the dark matter content in galaxies and clusters or measuring the Universe's expansion rate.The precision of these applications can be ...
