New test of Lorentz invariance using the MICROSCOPE space mission
Hélène Pihan-le Bars, Christine Guerlin, Aurélien Hees +11
We use data from the T-SAGE instrument on board the MICROSCOPE space mission to search for Lorentz violation in matter-gravity couplings as described by the Lorentz violating Stand…
Gravitational redshift test with the future ACES mission
Etienne Savalle, Christine Guerlin, Pacôme Delva +3
We investigate the performance of the upcoming ACES (Atomic Clock Ensemble in Space) space mission in terms of its primary scientific objective, the test of the gravitational redsh…
Search for transient variations of the fine structure constant and dark matter using fiber-linked optical atomic clocks
B. M. Roberts, P. Delva, A. Al-Masoudi +51
We search for transient variations of the fine structure constant using data from a European network of fiber-linked optical atomic clocks. By searching for coherent variations in…
Testing the gravitational redshift with Galileo satellites
P. Delva, N. Puchades, E. Schönemann +11
We present the results of the analysis of the GREAT (Galileo gravitational Redshift test with Eccentric sATellites) experiment from SYRTE (Observatoire de Paris), funded by the Eur…
A gravitational redshift test using eccentric Galileo satellites
P. Delva, N. Puchades, E. Schönemann +11
We report on a new test of the gravitational redshift and thus of local position invariance, an integral part of the Einstein equivalence principle, which is the foundation of gene…
Gaia Data Release 2: Processing the spectroscopic data
P. Sartoretti, D. Katz, M. Cropper +50
The Gaia Data Release 2 contains the 1st release of radial velocities complementing the kinematic data of a sample of about 7 million relatively bright, late-type stars. Aims: This…
