A complete view of the broad-line radio galaxy 4C+74.26 with XMM-Newton

This paper presents a timing study and broad-band spectral analysis of the broad-line radio galaxy 4C + 74.26 based on a 35-ks XMM-Newton observation. As found in previous data sets, the source exhibits no evidence for rapid variability, and its 0.2-10 keV light curve is well fitted by a constant. An excellent fit to the pn 0.3-12 keV spectrum was found using a continuum that combines an ionized and a neutral reflector, augmented by both cold and warm absorption. There is no evidence for a soft excess. The column of cold absorption was greater than the Galactic value, with an intrinsic column of similar to 1.9 x 10(21) cm(-2) . Evidence for the warm absorber was found from OVII and OVIII absorption edges with maximum optical depths of tau(max)(OVII) = 0.3 and tau(max)(OVIII) = 0.03, respectively. A joint pn-MOS fit increased the OVIII optical depth to tau(max)(OVIII) = 0.1. A simple, one-zone warm absorber model yielded a column of similar to 9 x 10(20) cm(-2) and an ionization parameter of similar to 60. Partial covering models provide significantly worse fits than ones including a relativistically broadened Fe K alpha line, strengthening the case for the existence of such a line. On the whole, the X-ray spectrum of 4C + 74.26 exhibits many features typical of both a radio-loud quasar (excess absorption) and radio-quiet Seyfert 1 galaxies (Fe K alpha emission and warm absorption). We also show that a spurious absorption line at similar to 8 keV can be created by the subtraction of an instrumental Cu K alpha emission line.
