Where Do High-Energy Cosmic Rays Come From? A Star’s Last Gasp

Gamma rays from this supernova remnant have been seen by telescopes since 2007, but exceptionally energetic light, when it was picked up by the HAWC Observatory in Mexico, piquing the interest of scientists hunting for galactic PeVatrons. When gamma rays reach our atmosphere, they can produce showers of charged particles that can be measured by telescopes on the ground.

“We were able to exclude that this emission is dominantly produced by electrons because the spectrum we got out just wouldn’t match the observations,” says Henrike Fleischhack, an astronomer at the Catholic University of America who had first attempted this analysis two years ago with just the HAWC data set.
