Cosmology and fundamental physics with the Euclid satellite
TLDR
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.

Large scale structure in Bekenstein's theory of relativistic modified Newtonian dynamics.
TLDR
It is shown that it may be possible to reproduce observations of the cosmic microwave background and galaxy distributions with Bekenstein's theory of MOND, and the evolution of the scalar field is akin to that of tracker quintessence fields.
In the realm of the Hubble tension—a review of solutions * * In honor of the seminal work by E Hubble [1]
 The simplest ΛCDM model provides a good fit to a large span of cosmological data but harbors large areas of phenomenology and ignorance. With the improvement of the number and the accuracy of
Evading equivalence principle violations, cosmological, and other experimental constraints in scalar field theories with a strong coupling to matter
We show that, as a result of nonlinear self-interactions, it is feasible, at least in light of the bounds coming from terrestrial tests of gravity, measurements of the Casimir force and those
Cosmological constraints on f(R) gravity theories within the Palatini approach
We investigate f(R) theories of gravity within the Palatini approach and show how one can determine the expansion history, H(a), for an arbitrary choice of f(R). As an example, we consider
STRUCTURE FORMATION IN THE SYMMETRON MODEL
Scalar fields, strongly coupled to matter, can be present in nature and still be invisible to local experiments if they are subject to a screening mechanism. The symmetron is one such mechanism that
Accelerating Cosmologies with an Anisotropic Equation of State: Vector Fields, Modified Gravity and Astrophysical Constraints
We investigate cosmologies where the accelerated expansion of the Universe is driven by a field with an anisotropic equation of state. We model such scenarios within the Bianchi I framework,
Dark spinor models in gravitation and cosmology
We introduce and carefully define an entire class of field theories based on non-standard spinors. Their dominant interaction is via the gravitational field which makes them naturally dark; we refer
