Euclid. I. Overview of the Euclid mission / Euclid Collaboration
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. Euclid is a medium-class mission in the Cosmic Vision 2015-2025 programme of the European Space Agency (ESA) that will provide high-resolution optical imaging, as well as near-infrared imaging and spectroscopy, over about 14,000 deg^2 of extragalactic sky. [...]

Euclid: Constraining linearly scale-independent modifications of gravity with the spectroscopic and photometric primary probes / Euclid Collaboration
The future Euclid space satellite mission will offer an invaluable opportunity to constrain modifications to Einstein's general relativity at cosmic scales. We focus on modified gravity models characterised, at linear scales, by a scale-independent growth of perturbations while featuring different testable types of derivative screening mechanisms at smaller non-linear scales [...]

Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the direct detection of gravitational waves with LIGO and Virgo, and many others. [...]

Prospects for Fundamental Physics with LISA / LISA Collaboration
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental physics. Given the very broad range of topics that might be relevant to LISA, we present here a sample of what we view as particularly promising directions, based in part on the current research interests of the LISA scientific community in the area of fundamental physics.

Robustness of cosmic neutrino background detection in the cosmic microwave background / Audren, Benjamin (IPT, Lausanne) ; Bellini, Emilio (ICC, Barcelona U.) ; Cuesta, Antonio J (ICC, Barcelona U.) ; Gontcho, Satya Gontcho A (ICC, Barcelona U.) ; Lesgourgues, Julien (CERN ; Annecy, LAPTH) ; Niro, Viviana (Madrid, Autonoma U ; Madrid, IFT) ; Pellejero-Ibanez, Marcos (IAC, La Laguna ; Laguna U., Tenerife) ; Pérez-Ràfols, Ignasi (ICC, Barcelona U.) ; Poulin, Vivian (Annecy, LAPTH) ; Tram, Thomas et al.
The existence of a cosmic neutrino background can be probed indirectly by CMB experiments, not only by measuring the background density of radiation in the universe, but also by searching for the typical signatures of the fluctuations of free-streaming species in the temperature and polarisation power spectrum. Previous studies have already proposed a rather generic parametrisation of these fluctuations, that could help to discriminate between the signature of ordinary free-streaming neutrinos, or of more exotic dark radiation models.

The parameter space of Cubic Galileon models for cosmic acceleration / Bellini, Emilio (Heidelberg U. ; Padua U. ; INFN, Padua) ; Jimenez, Raul (ICC, Barcelona U. ; ICREA, Barcelona ; CERN)
We use recent measurements of the expansion history of the universe to place constraints on the parameter space of cubic Galileon models. This gives strong constraints on the Lagrangian of these models. [...]
