Stringent Pulsar Timing Bounds on Light Scalar Couplings to Matter

David Benisty, Philippe Brax, Anne-Christine Davis

Pulsar Timing constraints on scalar-tensor theories with conformal and disformal couplings to matter are discussed. Reducing the dynamics to the motion in the centre of mass frame…

Casimir Tests of Scalar-Tensor Theories

Philippe Brax, Anne-Christine Davis, Benjamin Elder

We compute bounds and forecasts on screened modified gravity theories, specialising to the chameleon model in Casimir force experiments. In particular, we investigate the classical…

The Eccentricity Distribution of Wide Binaries

David Benisty, N. Wyn Evans, Anne-Christine Davis

Future Gaia and Legacy Survey of Space and Time data releases, together with wide area spectroscopic surveys, will deliver large samples of resolved binary stars with phase space c…

Hide and Seek: Screened Scalar Fields in Hydrogen and Muonium

Philippe Brax, Anne-Christine Davis, Benjamin Elder

We compute bounds on screened scalar field theories from hydrogen-like systems. New light scalar fields generically have a direct coupling to matter. Such a coupling is strongly co…

Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies

Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200

In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…

The Local Group Mass in the light of Gaia

David Benisty, Eugene Vasiliev, N. Wyn Evans +3

High accuracy proper motions (PMs) of M31 and other Local Group satellites have now been provided by the {\it Gaia} satellite. We revisit the Timing Argument to compute the total m…
