A high velocity ionised outflow and soft X - ray photosphere in the narrow emission line quasar PG 1211 + 143
We report on the analysis of a ∼60 ksec XMM-Newton observation of the bright, narrow emission line quasar PG1211+143. Absorption lines are seen in both EPIC and RGS spectra corresponding to Hand He-like ions of Fe, S, Mg, Ne, O, N and C. The observed line energies indicate an ionised outflow velocity of 0.08–0.1c. The highest energy lines require a column density of N H ∼5 × 10 23 cm −2 , at an...

متن کاملThe Mass of Quasar Broad Emission Line Regions
We show that the mass of ionized gas in the broad-line regions (BLRs) of luminous quasars is at least several hundred M , and probably of the order of 10 3–104 M . BLR mass estimates in several existing textbooks suggest lower values but pertain to much less luminous Seyfert galaxies or include only a small fraction of the ionized/emitting volume of the BLR. The previous estimates also fail to ...
متن کاملThe Velocity Field of Quasar Broad Emission Line Gas
In this Letter, the broad emission line (BEL) profiles of superluminal quasars with apparent jet velocities, βa > 10, (ultraluminal QSOs, or ULQSOs hereafter) are studied as a diagnostic of the velocity field of the BEL emitting gas in quasars. The ULQSOs are useful because they satisfy a very strict kinematical constraint, their parsec scale jets must be propagating within 12◦ of the line of s...
متن کاملX - 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/FR 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 ...
