Probing a Possible Vacuum Refractive Index with Gamma-Ray Telescopes
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
We have used a stringy model of quantum space-time foam to suggest that the vacuum may exhibit a non-trivial refractive index depending linearly on gamma-ray energy: eta -1 ~ E_gam…

Can TeVeS avoid Dark Matter on galactic scales?
Nick E. Mavromatos, Mairi Sakellariadou, Muhammad Furqaan Yusaf
A fully relativistic analysis of gravitational lensing in TeVeS is presented. By estimating the lensing masses for a set of six lenses from the CASTLES database, and then comparing…
