Can Gravitational Waves Be Detected in Quasar Microlensing?

Publication Date

Abstract

Studies of the lensed quasar Q0957+561A,B have shown evidence for microlensing in the brightness history of the quasar images. It had been suggested that a frequency offset between the brightness fluctuations in each of the two images might possibly be caused by gravitational radiation generated by a massive black hole binary at the center of the lensing galaxy. This paper demonstrates that the fluctuations produced by such a source of gravitational waves will be too small to account for the observed frequency offsets.
