Abstract: I discuss how to obtain conformally invariant expressions for the physical conserved currents in Unimodular Gravity, for both Einstein-Hilbert Lagrangian and the so-called Einstein Lagrangian. In this talk, first I give a brief introduction and motivation for Unimodular Gravity. I introduce an auxiliary unimodular metric that is Weyl invariant, and discuss the implications of this new symmetry for the conserved currents. Finally, I illustrate my results on the Painlevé-Gullstrand extension of Schwarzschild spacetime.
