Group leader: Prof. Rajeev Kumar Jain

Our group is interested in a broad range of topics in the early universe cosmology, focussing primarily on the physics of inflation, their imprints on the cosmic microwave background radiation, formation of primordial black holes as dark matter and their resulting observational imprints such as secondary gravitational waves, generation of primordial magnetic fields during inflation and associated non-Gaussianities, cosmological imprints of gauge/spectator fields during inflation, axion field dynamics, aspects of dark matter and relativistic effects in large scale structure. 

Research interests

• Theoretical cosmology, Inflation and alternatives, Physics of the early universe

• Cosmic Microwave Background (CMB), Anomalies in the CMB

• Primordial black holes and secondary gravitational waves

• Primordial magnetic fields and their observable imprints

• Primordial non-gaussianities, Cosmological imprints of dynamical gauge fields

• Dark matter, Axion field dynamics and cosmological implications

• Effective field theory of gravity

• Modified gravity, Dark energy

Research highlights

I am not taking any students (from outside IISc) for summer/winter projects or for a Master's thesis.
