LAG (Liquid Actuated Gravity) is an experiment funded by the INFN (National Institute of Nuclear Physics) for the development and testing of a new actuation technique for gravity experiments based on a liquid field mass. The basic idea of the experiment is to modulate the gravitational force acting on a test mass by controlling the level of a liquid in a suitable container, thereby producing a...
The increasing precision of spacecraft radiometric tracking data experienced in the last decade, combined with the huge amount of data collected from space missions and the long time span of the available datasets, has enabled a refined analysis of the Solar System dynamics. High precision tests of General Relativity can be performed through the measurement of the post-Newtonian parameters,...
The measurement of the Casimir Effect at a large distance, although challenging, is very interesting for the possible physical implications that stream from it. A successful measurement would allow to rule out or confirm Chameleon models as an explanation for dark energy; to put the strongest constraints on hypothetical long-range forces at the considered distances; to solve definitely the...
In recent decades, a growing international group of theorists, experimentalists, and observational astronomers have been working on searches for tiny hypothetical deviations from perfect local Lorentz symmetry in nature. One key motivation for this work is that the discovery of a violation of this principle may uncover aspects of a fundamental unified theory of physics. Tests and analysis...
Observations of metal absorption systems in the spectra of distant quasars allow stringent tests of the Einstein Equivalence Principle, through constraints on possible variations of the fine-structure constant. A new generation of high-resolution ultra-stable spectrographs, of which ESPRESSO is the first example, enables major advances in this field. Here we summarize the status quo and...
In modern cosmology, the electromagnetic signals coming from moving astronomical objects deliver the exhaustive physical information about the intriguing phenomena going on in the universe. Providing a solid theoretical instruction to analyze these signals is crucial in leading to new and important discoveries. As a diagnostic tool, the Doppler shift measurement is one of the most important...
