Light deflection angle through velocity profile of galaxies in $f(R)$ model

Vipin Kumar Sharma, Bal Krishna Yadav, Murli Manohar Verma

We explore a new realisation of the galactic scale dynamics via gravitational lensing phenomenon in power-law $f(R)$ gravity theory of the type $f(R)\propto R^{1+\delta }$ with $\delta <<1$ fo…
