GUEST: Gravitational Universe Exploration with Satellite Tracking. A passive satellite laser-ranging mission for the dark gravitational Universe
Diego Blas, Aurélien Hees, F. Javier Atapuerca +78
GUEST is a space mission concept whose central objective is the detection of gravitational waves (GWs) in the microhertz band -- a physics-rich frequency window that no other prese…

Einstein-Cartan pseudoscalaron inflation, reheating and nonthermal leptogenesis
Carlo Di Benedetto, Alessandro Di Marco, Emanuele Orazi +1
We study the postinflationary dynamics of an Einstein-Cartan-Holst gravity-motivated inflationary scenario, known as Einstein-Cartan pseudoscalaron inflation, coupled to a type-I s…

A Local Lorentz Invariance test with LAGEOS satellites
David Lucchesi, Massimo Visco, Roberto Peron +11
Strong theoretical arguments suggest that a breakdown of Lorentz Invariance could arise under some very particular conditions. From an experimental point of view, it is important t…
