# Searching for High-Energy Neutrino Emission from TeV Pulsar Wind Nebulae

## TL;DR

This study searches for neutrino emission from 35 gamma-ray emitting pulsar wind nebulae using 9.5 years of IceCube data, setting upper limits and constraining hadronic contributions.

## Contribution

It presents the first stacking analysis of neutrino emission from multiple PWNe, providing new constraints on hadronic processes in these objects.

## Key findings

- No significant neutrino signal detected
- Upper limits set on neutrino emission from PWNe
- Constraints placed on hadronic contribution in gamma-ray emission

## Abstract

Pulsar wind nebulae (PWNe) are main gamma-ray emitters in the Galactic plane. Although the leptonic scenario is able to explain most PWNe emission well, a hadronic contribution cannot be excluded. High-energy emission raises the possibility that gamma-rays are hadronically produced which inevitably leads to the production of neutrinos. We report a stacking analysis to search for neutrino emission from 35 PWNe that are very-high-energy gamma-ray emitters and the results using 9.5 years of all-sky IceCube data. In the absence of any significant correlation, we set upper limits on the total neutrino emission from those PWNe and constraints on the hadronic component.
