Machine Learning and Structure Formation in Modified Gravity
Jonathan C. Betts, Carsten van de Bruck, Christian Arnold +1
In General Relativity approximations based on the spherical collapse model such as Press--Schechter theory and its extensions are able to predict the number of objects of a certain…
An emulator-based halo model in modified gravity -- I. The halo concentration-mass relation and density profile
Cheng-Zong Ruan, Carolina Cuesta-Lazaro, Alexander Eggemeier +7
In this series of papers we present an emulator-based halo model for the non-linear clustering of galaxies in modified gravity cosmologies. In the first paper, we present emulators…
MGLenS: Modified gravity weak lensing simulations for emulation-based cosmological inference
Joachim Harnois-Déraps, Cesar Hernandez-Aguayo, Carolina Cuesta-Lazaro +4
We present MGLenS, a large series of modified gravity lensing simulations tailored for cosmic shear data analyses and forecasts in which cosmological and modified gravity parameter…
Euclid: Modelling massive neutrinos in cosmology -- a code comparison
J. Adamek, R. E. Angulo, C. Arnold +133
The measurement of the absolute neutrino mass scale from cosmological large-scale clustering data is one of the key science goals of the Euclid mission. Such a measurement relies o…
Making use of sub-resolution halos in N-body simulations
Joaquin Armijo, Carlton M. Baugh, Nelson D. Padilla +2
Conservative mass limits are often imposed on the dark matter halo catalogues extracted from N-body simulations. By comparing simulations with different mass resolutions, at …
Fast full -body simulations of generic modified gravity: derivative coupling models
César Hernández-Aguayo, Cheng-Zong Ruan, Baojiu Li +4
We present MG-GLAM, a code developed for the very fast production of full -body cosmological simulations in modified gravity (MG) models. We describe the implementation, numeric…
