Geometrical vs wave optics under gravitational waves
Raymond Angélil, Prasenjit Saha
We present some new derivations of the effect of a plane gravitational wave on a light ray. A simple interpretation of the results is that a gravitational wave causes a phase modul…
Testing General Relativity and Alternative Theories of Gravity with Space-based Atomic Clocks and Atom Interferometers
Ruxandra Bondarescu, Andreas Schärer, Philippe Jetzer +3
The successful miniaturisation of extremely accurate atomic clocks and atom interferometers invites prospects for satellite missions to perform precision experiments. We discuss th…
Testing scalar-tensor theories and PPN parameters in Earth orbit
Andreas Schärer, Raymond Angélil, Ruxandra Bondarescu +2
We compute the PPN parameters and for general scalar-tensor theories in the Einstein frame, which we compare to the existing PPN formulation in the Jordan frame for alterna…
Clocks around Sgr A*
Raymond Angélil, Prasenjit Saha
The S stars near the Galactic centre and any pulsars that may be on similar orbits, can be modelled in a unified way as clocks orbiting a black hole, and hence are potential probes…
Spacecraft Clocks and Relativity: Prospects for Future Satellite Missions
Raymond Angélil, Prasenjit Saha, Ruxandra Bondarescu +3
The successful miniaturization of extremely accurate atomic clocks invites prospects for satellite missions to perform precise timing experiments. This will allow effects predicted…
Relativistic redshift effects and the Galactic-center stars
Raymond Angélil, Prasenjit Saha
The high pericenter velocities (up to a few percent of light) of the S stars around the Galactic-center black hole suggest that general relativistic effects may be detectable throu…
