The curved spectrum of the young pulsar halo LHAASO J0248+6021 is explained by a time-dependent energy-loss bump in the electron spectrum that remains close to the cutoff, unifying it with the shifted bump observed in the older Geminga halo.

Spectral energy-loss bump and $\gamma$-ray pulsar halos
The curved spectrum of the young pulsar halo LHAASO J0248+6021 is explained by a time-dependent energy-loss bump in the electron spectrum that remains close to the cutoff, unifying it with the shifted bump observed in the older Geminga halo.
