Analysis of the new data from X-ray observations using NASA’s NuSTAR spacecraft and archival data from the agency’s Chandra X-ray space observatory, has yielded more insights into the nature of a pulsar wind nebula (PWN) named 3C 58. Results of the analysis, presented in a paper published April 12 on arXiv.org, could also shed more light on particle distribution in the population of known PWNe.
