Is PSR J0855$-$4644 responsible for the 1.4 TeV electron spectral bump hinted by DAMPE? astro-ph.HE DAMPE observation on the cosmic ray electron spectrum hints a narrow excess at $\sim$ 1.4 TeV. Although the excess can be ascribed to dark matter particles, pulsars and pulsar wind nebulae are believed to be a more...
