Probing Broad Absorption Line Quasar Outflows: X-ray Insights
Energetic outflows appear to occur in conjunction with active mass accretion onto supermassive black holes. These outflows are most readily observed in the ∼ 10% of quasars with broad absorption lines, where the observer’s line of sight passes through the wind. Until fairly recently, the paucity of X-ray data from these objects was notable, but now sensitive hard-band missions such as Chandra a...
متن کاملStrong X-ray Absorption in a Broad Absorption Line Quasar: Phl 5200
We present ASCA observations of the z 5 1.98 prototype broad absorption line quasar (BALQSO): PHL 5200. The source was detected in both SIS and GIS. A power-law spectrum (aE 5 0.620.6 10.9 ) with large intrinsic absorption (NH 5 1.321.1 12.3 3 10 cm) best describes the spectrum. Excess column density over the local Galactic value is required at the 99% confidence level. This detection suggests ...
متن کاملThomson Thick X-Ray Absorption in a Broad Absorption Line Quasar, PG 0946+301.
We present a deep ASCA observation of a broad absorption line quasar (BALQSO) PG 0946+301. The source was clearly detected in one of the gas imaging spectrometers, but not in any other detector. If BALQSOs have intrinsic X-ray spectra similar to normal radio-quiet quasars, our observations imply that there is Thomson thick X-ray absorption (NH greater, similar1024 cm-2) toward PG 0946+301. This...
متن کاملA Balmer-line Broad Absorption Line Quasar
I report the discovery of blueshifted broad absorption line (BAL) troughs in at least six transitions of the Balmer series of hydrogen (Hβ to H9) and in Ca II, Mg II and excited Fe II in the quasar SDSS J125942.80+121312.6. This is only the fourth active galactic nucleus known to exhibit Balmer absorption, all four in conjunction with low-ionization BAL systems containing excited Fe II. The sub...
متن کاملIs X-ray Absorption from Quasar Absorption Line Systems Detectable?
Using the known properties and statistics of intervening quasar absorption systems, we calculate the cumulative absorption out to high redshifts at soft X-ray (E < 1 keV) energies. Although photoelectric absorption in quasar absorption systems provides a signiicant source of opacity at the lowest X-ray energies, the imprint of this absorption is not readily observable since it is generally mask...
