We calculate the strong lensing probability as a function of the image-separation \Delta \theta in TeVeS ( tensor-vector-scalar ) cosmology , which is a relativistic version of MOND ( MOdified Newtonian Dynamics ) .
The lens , often an elliptical galaxy , is modeled by the Hernquist profile .
We assume a flat cosmology with \Omega _ { b } = 1 - \Omega _ { \Lambda } = 0.04 and the simplest interpolating function \mu ( x ) = { min } ( 1 ,x ) .
For comparison , we recalculated the probabilities for lenses by Singular Isothermal Sphere ( SIS ) galaxy halos in LCDM with Schechter-fit velocity function .
The amplification bias is calculated based on the magnification of the second bright image rather than the total of the two brighter images .
Our calculations show that the Hernquist model predicts insufficient but acceptable probabilities in flat TeVeS cosmology compared with the results of the well defined combined sample of Cosmic Lens All-Sky Survey ( CLASS ) and Jodrell Bank/Very Large Array Astrometric Survey ( JVAS ) ; at the same time , it predicts higher probabilities than SIS model in LCDM at small image separations .
