Abstract
We construct a N = 2 supersymmetric extension of Newton-Cartan gravity by gauging a N = 2 supersymmetric extension of the Bargmann algebra. Due to technical complications we restrict the construction to the three-dimensional case. We discuss the gauge-fixing of the resulting Newton-Cartan supergravity theory to a Galilean supergravity that contains the Newton potential. An unusual feature is that, in order to realize the supersymmetry on the Newton potential, we need to introduce a dual Newton potential as well. Together, Newton potential and dual potential, they form a holomorphic function of the two spatial coordinates. We briefly discuss the four-dimensional case.
