The X-ray spectrum of the broad-line radio galaxy 3C445

The first X-ray spectrum of the giant radio galaxy 3C445 is reported. The spectrum is well fitted by a power law of slope close to the 'canonical' value for emission-line galaxies. This suggests that the X-ray emission of 3C445 is dominated by its Seyfert nucleus and is not directly related to the radio flux, a conclusion supported by the large low-energy absorption evident from the X-ray spectrum. The implied intrinsic absorbing column of ∼ 1.7 x 1023cm-2 is the largest ever seen for such a high-luminosity source as 3C445. (author)
