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…
Searching for large dark matter clumps using the Galileo Satnav clock variations
Bruno Bertrand, Pascale Defraigne, Aurélien Hees +8
This study presents bounds on transient variations of fundamental constants, with typical timescales ranging from minutes to months, using clocks in space. The underlying phenomeno…
Probing Primordial Black Holes and Dark Matter Clumps in the Solar System with Gravimeter and GNSS Networks
Michal Cuadrat-Grzybowski, Sébastien Clesse, Pascale Defraigne +2
We show that Global Navigation Satellite Systems (GNSS) and gravimeters on Earth and in space can potentially offer the most accurate direct measurement of local density of near-Ea…
Observing dark matter clumps and asteroid-mass primordial black holes in the solar system with gravimeters and GNSS networks
Bruno Bertrand, Michal Cuadrat-Grzybowski, Pascale Defraigne +2
In this proceedings, we study the possible gravitational impact of primordial black holes (PBHs) or dark matter (DM) clumps on GNSS satellite orbits and gravimeter measurements. It…
