What is Gravity and Matter with Asymptotic Safety about?

Building a consistent Quantum Theory of Gravity is one of the most challenging aspects of modern theoretical physics. In the past couple of years, new attempts have been made along the path of ``asymptotic safety'' through the use of Exact Renormalisation Group Equations, which hinge on the existence of a non-trivial fixed point of the flow equations. We will first summarize the major results that have been obtained along these lines, then we will consider the effect of introducing matter fields into the theory. Our analyses show that in order to preserve the existence of the fixed point one must satisfy some constraints on the matter content of the theory.
