The amplification of a light beam due to intervening gravitational waves is studied. The previous Jordan frame result according to which the amplification is many orders of magnitude larger in scalar-tensor gravity than in general relativity does not hold in the Einstein conformal frame. Lensing by gravitational waves is discussed in relation to the ongoing and proposed VLBI observations aimed at detecting the scintillation effect.

  1. Close Hyperbolic Encounters In f(R) Gravity

    gr-qc 2025-06 reject novelty 5.0 of 10

    In f(R) gravity, close hyperbolic black-hole encounters emit a scalar gravitational-wave mode whose promised detectability is not supported by the paper's own amplitude formulas.
