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…
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…
