NuSTAR discovery of the hard X-ray emission and a wide-band X-ray spectrum from the Pictor A western hot spot

Autor: Yuji Sunada, Arisa Morimoto, Makoto S Tashiro, Yukikatsu Terada, Satoru Katsuda, Kosuke Sato, Dai Tateishi, Nobuaki Sasaki

Utilizing \textit{Chandra}, \textit{XMM-Newton} and \textit{NuSTAR}, a wide-band X-ray spectrum through 0.2 to 20 keV is reported from the western hot spot of Pictor A. In particular, the X-ray emission is significantly detected in the 3 to 20 keV ba
