Detection of the Characteristic Pion-Decay Signature in Supernova Remnants
Open accessAbstract
Accelerated Protons: Although cosmic rays were first detected a hundred years ago, their origin is still not fully understood. Comic rays are high-energy particles, mostly protons, which bombard Earth from outer space. Most of those that originate from within our galaxy are thought to be accelerated in the shock waves from the explosion of massive stars, or supernovae. Protons accelerated in a supernova remnant will collide with interstellar material producing pions, a type of subatomic particle, which will then decay into gamma rays. Ackermann et al. (p. 807 ) present measurements of the energy spectra of two supernova remnants in our galaxy, IC443 and W44, in the energy range below 100 MeV down to 60 MeV with the Fermi Gamma-Ray Space Telescope. The spectra reveal the pion-decay feature that is a signature of accelerated protons.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
