Euclid preparation. The shape of halo profiles in CDM and non-standard cosmologies
Euclid Collaboration, L. Pizzuti, G. Y. Ferron +304
We study the shape of three-dimensional and projected dark-matter halo profiles extracted from cosmological -body simulations in CDM and non-standard cosmologies, using the \…
Probing the two-body decaying dark matter scenario with weak lensing and the cosmic microwave background
Jozef Bucko, Sambit K. Giri, Fabian Hervas Peters +1
Decaying dark matter (DDM) scenarios have recently regained attention due to their potential ability to resolve the well-known clustering (or ) tension between weak lensing (W…
BEoRN: A fast and flexible framework to simulate the epoch of reionisation and cosmic dawn
Timothée Schaeffer, Sambit K. Giri, Aurel Schneider
In this study, we introduce BEoRN (Bubbles during the Epoch of Reionisation Numerical Simulator), a publicly available Python code that generates three-dimensional maps of the 21-c…
Cosmological forecast of the 21-cm power spectrum using the halo model of reionization
Aurel Schneider, Timothée Schaeffer, Sambit K. Giri
The 21-cm power spectrum of reionization is a promising probe for cosmology and fundamental physics. Exploiting this new observable, however, requires fast predictors capable of ef…
Constraining dark matter decays with cosmic microwave background and weak lensing shear observations
Jozef Bucko, Sambit K. Giri, Aurel Schneider
From observations at low and high redshifts, it is well known that the bulk of dark matter (DM) has to be stable or at least very long-lived. However, the possibility that a small…
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…
