**We welcome everyone to this event, from upper-level undergraduate students, post-docs and faculty to the general public. Come join us!**

Abstract:
We will discuss experimental results studying the wave-vortex interaction arising from rotating fluid
and superfluid flows. The dynamical equation describing the wave-vortex interaction can be mapped to
scalar fields propagating on an effective rotating black hole. This opens the possibility of studying a
variety of rotating black hole processes in hydrodynamic systems. I will summarise our experimental
efforts resulting in the detection of geodesic motion, quasi-normal modes and superradiance in normal
fluids at room temperature and pressure. I will end by introducing by presenting our new experimental
system, based on superfluid optomechanics, allowing us to study rotating black hole effects in the
quantum domain.
