Unusual high-redshift radio broad absorption-line quasar 1624+3758 [PDF]

Monthly Notices of the Royal Astronomical Society, 2005
We present observations of the most radio-luminous broad absorption-line (BAL) quasar known, 1624+3758, at redshift z= 3.377. The quasar has several unusual properties. (1) The Fe II UV191 1787-Å emission line is very prominent.

Strong X-Ray Absorption in a Broad Absorption Line Quasar: PHL 5200 [PDF]

Astrophysical Journal, 1995
We present ASCA observations of the z=1.98 prototype broad absorption line quasar (BALQSO): PHL 5200. The source was detected in both SIS and GIS. A power-law spectrum (αE=0.6−0.6+0.9) with large intrinsic absorption (NH=1.3−1.1+2.3×1023 cm−2) best ...

Broad Absorption Line Disappearance/Emergence in Multiple Ions in a Weak Emission-line Quasar [PDF]

Astrophysical Journal Letters, 2019
We report the discovery of the disappearance of Mg ii, Al iii, C iv, and Si iv broad absorption lines (BALs) at the same velocity (0.07c), accompanied by a new C iv BAL emerging at a higher velocity (up to 0.11c), in the quasar J0827+4252 at z = 2.038 ...

Variability in quasar broad absorption line outflows – III. What happens on the shortest time-scales? [PDF]

Monthly Notices of the Royal Astronomical Society, 2013
Broad absorption lines (BALs) in quasar spectra are prominent signatures of high-velocity outflows, which might be present in all quasars and could be a major contributor to feedback to galaxy evolution.
