| 英文摘要 | It has been suggested that relativistic jets in quasars may contain a considerable amount of thermal matter. In this paper, we explore the possibility that the Kalpha line from the thermal matter may appear at tens of keV due to a high Doppler blue-shift. In the jet comoving frame, the energy density of photons originally emitted by the accretion disk and reflected off the broad line region clouds dominates over that of photons of other origin. We discuss the photoionization states of the thermal matter and find that the irons elements are neutral. The high metallicity in quasars enhances the possibility to detect the thermal matter in the relativistic jet in some radio-loud quasars. A highly Doppler blue-shifted Kalpha line may be detected. We make a prediction for 3C 273, in which the Kalpha line luminosity might be of the order 3.0 x 10(44) erg s(-1) with an equivalent width of 2.4 keV. Such a line could be detected in a future mission. |
