Abstract
Young supernova remnants are likely to be bright sources of energetic photons and neutrinos through the collision of particles accelerated inside the remnant1–3. Interactions of accelerated particles in the expanding envelope or in ambient radiation fields will also produce secondary photons and neutrinos at some level. If >1039 erg s−1 in protons above 10 TeV is injected into the target region, TeV photons from SN1987A could be observable with present detectors4–6. Synchrotron X rays and γ-rays up to 10 MeV, generated by accelerated electrons, may well also be detectable. We discuss a pulsar wind model for acceleration of particles and find that it would produce observable signals if the spin period of the pulsar is ≤ 10 ms.
