Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
Euclid preparation. XLI. Galaxy power spectrum modelling in real space
Euclid Collaboration, A. Pezzotta, C. Moretti +246
We investigate the accuracy of the perturbative galaxy bias expansion in view of the forthcoming analysis of the Euclid spectroscopic galaxy samples. We compare the performance of…
Frequency-Domain Distribution of Astrophysical Gravitational-Wave Backgrounds
Yonadav Barry Ginat, Robert Reischke, Ivan Rapoport +1
The superposition of many astrophysical gravitational wave (GW) signals below typical detection thresholds baths detectors in a stochastic gravitational wave background (SGWB). In…
Non-Gaussian assembly bias from a semi-analytic galaxy formation model
M. Marinucci, V. Desjacques, A. Benson
We use mock galaxy catalogues produced with the semi-analytic code GALACTICUS to study the dependence of the non-Gaussian bias parameter on the mass assembly history of…
Assembly bias in the local PNG halo bias and its implication for constraints
Titouan Lazeyras, Alexandre Barreira, Fabian Schmidt +1
We use -body simulations to study halo assembly bias (i.e., the dependence of halo clustering on properties beyond total mass) in the density and primordial non-Gaussianity (PNG…
Dynamical Friction in fuzzy dark matter: circular orbits
Robin Buehler, Vincent Desjacques
We investigate the dynamical friction (DF) acting on circularly-moving perturbers in fuzzy dark matter (FDM) backgrounds. After condensation, FDM is described by a single wave func…
