Researchers detect polarized
emission from “the Crab”
for the first time
in hard X-ray band
Researchers from Japan and Sweden, including Jun Kataoka, professor of astrophysics at Waseda University, collaborated to develop the polarimeter, PoGO+. Using this device, the international research group succeeded in detecting polarized emission from the Crab system, a bright celestial X-ray source which is both a supernova remnant and a pulsar, for the first time in the hard X-ray band (~20 – 160 keV).
This study was published in Scientific Reports on August 10.
