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…
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…
Report of the Topical Group on Cosmic Probes of Fundamental Physics for for Snowmass 2021
Rana X. Adhikari, Luis A. Anchordoqui, Ke Fang +118
Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probe…
Testing modified gravity via Yukawa potential in two body problem: Analytical solution and observational constraints
David Benisty
Many alternative theories of gravity screens a Yukawa-type potential. This article shows Keplerian-type parametrization as a solution of Yukawa type potential accurate equations of…
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…
On the Robustness of the Constancy of the Supernova Absolute Magnitude: Non-parametric Reconstruction \& Bayesian approaches
David Benisty, Jurgen Mifsud, Jackson Levi Said +1
In this work, we test the robustness of the constancy of the Supernova absolute magnitude using Non-parametric Reconstruction Techniques (NRT). We isolate the luminosity dist…
Unifying Inflation with early and late Dark Energy in Multi-Fields: Spontaneously broken scale invariant TMT
Eduardo Guendelman, Ramon Herrera, David Benisty
A unified multi scalar field model with three flat regions is discussed. The three flat regions are the inflation, early and late dark energy epochs. The potential is obtained by a…
