The presence of quasi-periodic pulsations in solar flares, temporary periodic signatures in emitted radiation at different wavelengths, may reveal important information about the energy release process but the origin of this phenomenon is not well understood. One approach to addressing this issue is to develop models of oscillatory reconnection and to explore how reconnection itself may generate oscillatory behavior and waves. To this end, we present the results of 2D magnetohydrodynamic simulations of magnetic reconnection between two twisted magnetic flux ropes, leading to the merger of the flux ropes, and discuss the origins of the resulting periodic pulsations and the waves which are emitted.
