X-ray thermal emission from the jet of M87 with Chandra
Abstract
With new calibration data, thermal emission from the jet of radio galaxy M87 is studied with about 700 ks archival data with Chandra. For nucleus, HST-1, knot D, X-ray energy spectra is well fitted with a power law. However, For knot A, a power law model is rejected with a high significance and an X-ray energy spectra is well fitted with a combination model of a power law and an apec model of 0.2 keV and a metal abundance 0.00. Thermal emission from knot A is confirmed.
