Possible Neutrino Emission from the Pulsar Wind Nebula G63.7+1.1.

Abstract (from CDS):

We report on our finding of an excess of $5{4}_{-15}^{+16}$ neutrinos at the location of the pulsar wind nebula (PWN) G63.7+1.1. By analyzing the IceCube track-like neutrino data for a group of 14 PWNe, which are selected as targets because of their reported association with molecular clouds, G63.7+1.1 is found to be the only one detected with neutrino emission, and the post-trail significance for the detection is 3.2σ. Previously, this PWN was estimated to have an age of ≳8 kyr, contain a candidate pulsar detected in X-rays, and have a distance of ∼6 kpc. More importantly, and related to the PWN's possible neutrino emission, surrounding molecular materials are seen to interact with the PWN. On the basis of these properties, we examine the proton-proton interactions as the process for the neutrino production. The PWN (or the pulsar) can provide sufficient energy to power the required high-energy (HE) protons. This possibly first neutrino-emitting case in our Galaxy, with problems or other possibilities to be solved or examined, may reveal to us that PWNe are the significant Galactic HE neutrino sources.
