Description
A modification of the Einstein-Hilbert Lagrangian by introducing an explicit coupling between the gravitational field, given by the Weyl tensor, and the matter-energy content, given by the stress-energy tensor, was proposed to explain flat galactic rotation curves without the exotic (non-baryonic) dark matter (DM) [Qadir, A., and Lee, H.W., IJMPD, 28, 2040014, (2019)], as Modified Relativistic Dynamics (MORD) and later called Weyl-Incorporated Gravity (WIG) [Qadir, A., Shahid, A., and Tahir, N., AJOM (accepted 2026)]. It was seen that a single value of the coupling constant $\lambda$ successfully explained the rotational velocities of eight edge-on spiral galaxies. Here we present a brief review of WIG and mention future prospects.
