Strong field gravitational lensing in the Brans-Dicke theory has been studied. The deflection angle for photons passing very close to the photon sphere is estimated for the static spherically symmetric space-time of the theory and the position and magnification of the relativistic images are obtained. Modeling the super massive central object of the galaxy by the Brans-Dicke space-time, numerical values of different strong lensing observable are estimated. It is found that against the expectation there is no significant scalar field effect in the strong field observable lensing parameters. This observation raises question on the potentiality of the strong field lensing to discriminate different gravitational theories.

Strong gravitational lensing effects around rotating regular black holes
Strong lensing by rotating regular black holes shifts lensing coefficients, image positions, magnifications, and time delays relative to Kerr, with M87* time delays differing by up to tens of hours while image positio...
