abstract

It is suggested that gravity waves could, in several cases, be detected by means of already (or shortly to be) available technology, independently of current efforts of detection. The present is a follow-up on a recently suggested detection strategy based on gravity-wave-induced deviations of null geodesics. The new development is that a way was found to probe the waves close to the source, where they are several orders of magnitude larger than on the Earth. The effect translates into apparent shifts in stellar angular positions that could be as high as $10^{-7}$ arcsec, which is just about the present theoretical limit of detectability. (Calculation improved; results unchanged.)

  1. New test of modified gravity with gravitational wave experiments

    gr-qc 2025-09 conditional novelty 6.0

    For a stationary, isotropic gravitational wave background, three-point correlations are produced only by scalar polarizations, giving a new null test for modified gravity.
