High-Energy Neutrino Signatures of Newborn Pulsars In the Local Universe

Understand

Charged particles can be accelerated to higher than PeV energies in the electro-magnetic wind of a fast-spinning newborn pulsar to produce high-energy neutrinos, through hadronuclear interactions in the supernova remnant.

• Here we explore the detectability and observational signatures of these high-energy neutrinos.
• We show that their spectral index varies approximately from 1.5 to 2, depending on the relevant pulsar properties and observation time.
• We also apply the scenario to existing young pulsars in the local universe and find the corresponding neutrino flux well below current detection limits.
