Quasi-automatic software support for Gaia ground based optical tracking
S. Bouquillon, C. Barache, T. Carlucci +6
The ESA Gaia satellite mission will create a catalog of 1 billion stars with unprecedented astrometric precision. To achieve its aim in terms of astrometric precision, a ground bas…
GBOT: ground based optical tracking of the Gaia satellite
Martin Altmann, Sebastien Bouquillon, Francois Taris +6
Gaia, the 1 billion star, high precision, astrometric satellite will revolutionise our understanding in many areas of astronomy ranging from bodies in our Solar System to the forma…
International Optical Clock Comparison Using the European Optical Fiber Network
Marco Pizzocaro, Clara Zyskind, Anne Amy-Klein +41
Optical clocks have achieved remarkable estimated fractional frequency uncertainties reaching the level and below, enabling applications in fundamental physics, general…
Real-time phase control methods for cold-atom interferometry
Mohamed Guessoum, Nathan Marliere, Charbel Cherfan +2
We present two methods to achieve real-time inertial phase compensation in atom interferometers. Both methods, based on jumps of the position of the retroreflection mirror or frequ…
Validation of optical pathlength stability in a LISA test-bench demonstrator
Shivani Harer, Maxime Vincent, Hubert Halloin +40
The Laser Interferometer Space Antenna (LISA) observatory is a future L3 mission of the European Space Agency (ESA) to detect gravitational waves, set to launch in 2035. The detect…
Primordial observables of explicit diffeomorphism violation in gravity
Mohsen Khodadi, Nils A. Nilsson, Gaetano Lambiase +1
We investigate the potential for current and future gravitational-wave detectors to observe imprints of explicit diffeomorphism violation in primordial signals. Starting from a sim…
