The purpose of this Group is to advance the scientific understanding of our universe in Pakistan, developing cosmological theories that are both mathematically consistent and observationally testable. The Group of Gravitation and Cosmology is a part of Department of Mathematics which in turn is part of Faculty of Sciences at University of the Punjab. It was suggested by Prof. Muhammad Sharif during an International Conference on Relativistic Astrophysics which was organized by Department of Mathematics to announce the relativity group within the department officially. In recent years, the group’s main effort has been towards the discussion of thermodynamics, inflation, gravitational lensing with the viable universe models. Furthermore, the effects of electromagnetic field on self-gravitating star configuration have also been investigated.
