Gravitational Lensing by Black Holes in Einstein Quartic Gravity
arXiv:2007.05341 · doi:10.1103/PhysRevD.103.024017
Abstract
We investigate gravitational lensing effects of spherically symmetric black holes in Einstein Quartic Gravity (EQG). Using an approximate analytic solution obtained by continued fraction methods we consider the predictions of EQG for lensing effects by supermassive black holes at the center of our galaxy and others in comparison with general relativity (GR). We numerically compute both time delays and angular positions of images and find that they can deviate from GR by as much as milliarcseconds, suggesting that observational tests of EQG are feasible in the near future. We discuss the challenges of distinguishing the predictions of EQG from those of Einstein Cubic Gravity.
