Cosmology and fundamental physics with the Euclid satellite
- L. Amendola, S. Appleby, T. Złośnik
- PhysicsLiving Reviews in Relativity
- 1 June 2016
This review is meant to provide a guide to the scientific themes that will underlie the activity of the group during the preparation of the Euclid mission and discusses five broad topics: dark energy and modified gravity, dark matter, initial conditions, basic assumptions and questions of methodology in the data analysis.

A bstractWe show that in a general $ \mathcal{N} = {1} $ supergravity with N ≫ 1 scalar fields, an exponentially small fraction of the de Sitter critical points are metastable vacua. Taking the…

A search for ultralight axions using precision cosmological data
- R. Hložek, D. Grin, D. Marsh, P. Ferreira

- 10 October 2014
Ultra-light axions (ULAs) with masses in the range 10^{-33} eV 10^{-24} eV, ULAs are indistinguishable from standard cold dark matter on the length scales probed, and are thus allowed by these data.…
Axion dark matter, solitons and the cusp–core problem
Self-gravitating bosonic fields can support stable and localised field configurations. For real fields, these solutions oscillate in time and are known as oscillatons. The density profile is static,…
Working Group Report: New Light Weakly Coupled Particles

Dark sectors, consisting of new, light, weakly-coupled particles that do not interact with the known strong, weak, or electromagnetic forces, are a particularly compelling possibility for new…
Galaxy UV-luminosity function and reionization constraints on axion dark matter

If the dark matter (DM) were composed of axions, then structure formation in the Universe would be suppressed below the axion Jeans scale. Using an analytic model for the halo mass function of a…
Constraining the mass of light bosonic dark matter using SDSS Lyman-α forest

If a significant fraction of the dark matter in the Universe is made of an ultra-light scalar field, named fuzzy dark matter (FDM) with a mass of the order of 10^−22 − 10^−21 eV, then its de Broglie…
