Broadband nuclear emission in two radio-loud BAL quasars

摘要: The X-ray weakness of broad absorption line (BAL) quasars in comparison to non-BAL objects is possibly caused by the emission shielding material near equatorial plane. On other hand, radio-loud BALQSOs are more loud than radio-quiet ones. This suggests that part may arise from radio jet. To investigate this possibility, we modelled nuclear spectra two BALQSOs. We focus on very centres these objects. source was approximated a single, homogeneous component produces synchrotron and inverse-Compton (IC) radiation. simplicity model allowed us estimate basic physical parameters emitting regions, using universal analytic approach. Such methods have already been used blazars. For first time propose solution for quasars. In addition, radiation accretion disk its corona compare them with jets' spectra. find case luminous 3C270.1, continuum dominated non-thermal, IC innermost parts However, core lobe-dominated PG 1004+130 probably too weak produce significant observed emission. A large contribution produced our model. it then exceeds flux. Because intrinsic postulated recently NuSTAR observations, disk-corona still account X-rays source. spectrum must nevertheless be conclude jet-linked present strong sources, but fraction seems scale jet power.
