I will present a non-technical overview of recent developments in the analysis of correlation functions in Conformal Field Theory in D dimensions, performed in momentum space. For 3-point functions this approach is essential in order to derive non perturbative solutions of correlators with stress energy tensors and investigate the role of the conformal anomaly in gravity and the anomaly action. For the graviton/photon/photon correlator I will present the exact form of these solutions, derived recently. Applications of these analysis are very broad, from solid state (topological insulators and Weyl semimetals) to astrophysics (holographic non-gaussianities and gravitational lensing).
