Ray absorption and an X-ray jet in the radio-loud broad absorption-line quasar PG 1004+130

We investigate the X-ray properties of PG 1004+130, a radio-loud broad absorption-line (BAL) quasar with a hybrid FR I/II radio morphology. This optically bright, low-redshift quasar was undetected by Einstein, marking it as anomalously X-ray weak relative to other radio-loud quasars. The 22.2 ks XMM-Newton and 41.6 ks Chandra observations presented here are the first X-ray detections of PG 1004+130 and constitute the highest spectral quality X-ray observations of a radio- loud BAL quasar available to date. The Chandra ACIS-S spectrum shows evidence for complex soft X-ray absorption not detected in the data obtained 1.7 yr previously with XMM-Newton, with a best-fit intrinsic column density of N-H = 1.2; 10(22) cm(-2) for the preferred partial- covering model. There is no significant difference in the hard- band power- law photon index of Gamma approximate to 1.5 between the two observations. The Chandra image also reveals extended X- ray emission approximate to 8'' (30 kpc) southeast of the nucleus, aligned with the FRI jet but upstream of the 1.4 GHz radio brightness peak. The jet is not detected by HST, and the optical upper limit rules out a simple singlecomponent synchrotron interpretation of the radio-to-X-ray emission. The multiwavelength characteristics of the PG 1004+130 jet, including its relatively flat X-ray power law and concave spectral energy distribution, are similar to those of powerful FRII jets. The lack of strong beaming in PG 1004+130 limits the efficiency of inverse Compton upscattering, and we consider the X-ray emission to most likely arise from a second synchrotron component generated by highly energetic electrons.
