Pulsar wind nebulae (PWNe) are main gamma-ray emitters in the Galactic plane.
They are diffuse nebulae that emit non-thermal radiation. Pulsar winds,
relativistic magnetized outflows from the central star, shocked in the ambient
medium produce a multiwavelength emission from the radio through gamma rays.
Although the leptonic scenario is able to explain most PWNe emission, a
hadronic contribution cannot be excluded. A possible hadronic contribution to
the high-energy gamma-ray emission inevitably leads to the production of
neutrinos. Using 9.5 years of all-sky IceCube data, we report results from a
stacking analysis to search for neutrino emission from 35 PWNe that are
high-energy gamma-ray emitters. In the absence of any significant correlation,
we set upper limits on the total neutrino emission from those PWNe and
constraints on hadronic spectral components.
