But more mundane explanations are also plausible: Positrons might be spewed from nearby pulsars, the spinning remnants of exploded stars, for example. (sciencenews.org)
The researchers then combined that information with a map of nearby pulsars to find — for the first time — the probability of a definitive detection over time. (sciencedaily.com)
«Thanks to its wide field of view, HAWC provides unique measurements on the very - high - energy gamma - ray profiles caused by the particle diffusion around nearby pulsars, which allows us to determine how fast the particles diffuse more directly than previous measurements,» says Hao Zhou, now a scientist at the Los Alamos National Laboratory in New Mexico and Michigan Tech alumnus.
