A Catalog of Pulsar X-ray Filaments

Kavli Affiliate: Roger W. Romani | First 5 Authors: Jack T. Dinsmore, Roger W. Romani, , , | Summary: We present the first Chandra X-ray Observatory (CXO) catalog of "pulsar X-ray filaments," or "misaligned outflows." These are linear, synchrotron radiating features powered by ultra-relativistic electrons and positrons that escape from bow shock pulsars. The filaments […]
