Understanding the reason for the observed accelerated expansion of the Universe
represents one of the fundamental open questions in physics. In cosmology, a classification …

We review recent progress in the construction of modified gravity models as alternatives to
dark energy as well as the development of cosmological tests of gravity. Einstein's theory of …

We study the implications of Planck data for models of dark energy (DE) and modified gravity
(MG) beyond the standard cosmological constant scenario. We start with cases where the …

We present the current accounting of systematic effect uncertainties for the Low Frequency
Instrument (LFI) that are relevant to the 2015 release of the Planck cosmological results …

For the last 100 years, General Relativity (GR) has taken over the gravitational theory mantle
held by Newtonian Gravity for the previous 200 years. This article reviews the status of GR in …

We implement the effective field theory (EFT) approach to dark energy and modified gravity
in the public Einstein-Boltzmann solver camb. The resulting code, which we dub eftcamb, is …

We forecast the main cosmological parameter constraints achievable with the CORE space
mission which is dedicated to mapping the polarisation of the Cosmic Microwave …

We introduce eftcamb/EFTCosmoMC as publicly available patches to the commonly used
camb/CosmoMC codes. We briefly describe the structure of the codes, their applicability and …

We propose a novel method to test the gravitational interactions in the outskirts of galaxy
clusters. When gravity is modified, this is typically accompanied by the introduction of an …

Following the first demonstration of a levitated nanosphere cooled to the quantum ground
state in 2020 (U. Delić, et al. Science, vol. 367, p. 892, 2020), macroscopic quantum sensors …
