Chronometric geodesy: methods and applications
P. Delva, H. Denker, G. Lion
In section 2, we introduce fundamental concepts of GR concerning the measurement of time, relativistic reference systems and we review the recent literature of chronometric geodesy…
Direct comparisons of European primary and secondary frequency standards via satellite techniques
F. Riedel, A. Al-Masoudi, E. Benkler +46
We carried out a 26-day comparison of five simultaneously operated optical clocks and six atomic fountain clocks located at INRIM, LNE-SYRTE, NPL and PTB by using two satellite-bas…
The relativistic glider revisited
L. Bergamin, P. Delva, A. Hees
In this paper we analyze some aspects of the "relativistic glider" proposed by Guéron and Mosna more in detail. In particular an explicit weak gravity and low velocity expansion i…
Vibrating systems in Schwarzschild spacetime: towards new experiments in gravitation?
L. Bergamin, P. Delva, A. Hees
In this paper the effects of vibrations at high frequencies onto a freely falling two-body system in Schwarzschild spacetime are investigated. As reference motion of the same syste…
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…
