Non-Locality in the Cosmic Microwave Background — •Dipanshu Gupta — Goethe Universität, Frankfurt am Main

We want to explore signatures of Quantum Gravity in cosmology in the UV spectrum. We do so by studying the non-local effects one expects in a fundamental theory of gravity and derive its consequences. We study Non-Commutative Geometry (NCG) and Generalised Uncertainty Principle (GUP) in this context. In principle, we would like to put a bound on the non-commutative parameter in both these theories using Cosmic Microwave Background (CMB) data from the Planck satellite.
