Pulsar wind nebulae (PWNe) experience significant evolution in reverberation phase, when the reverse shock created by the supernova explosion travels back towards the pulsar, compressing the wind bubble.

We numerically studied the radiative properties of the reverberation phase of several well-characterized PWNe and discovered that even the Crab Nebula, associated to the more energetic pulsar of the sample we consider, has a period in its future time evolution where the X-ray luminosity will exceed the spin-down power at the time.

In fact, all nebulae in our sample are expected to have a period of radio, X-ray, and GeV superefficiency, and most will also have a period of TeV superefficiency. We then explored a broad range of PWN models to study their reverberation and superefficiency phases in a systematic way in order to analyze how many Galactic PWNe are expected to be reverberating, or in a superefficiency at any given time.

We also provide predictions for the future evolution of the magnetar nebula J1834.9-0846 along the next 50 years. I will talk about the characterization of the superefficiency period we discovered in our numerical study.
