A uniform analysis of the Lyman alpha forest at z = 0-5: III. HST FOS Spectral Atlas
Jill Bechtold, Adam Dobrzycki, Brenda Wilden +5
We analyzed the absorption line spectra of all quasars observed with the high resolution gratings of the Faint Object Spectrograph on board the Hubble Space Telescope. We examined…
Chandra Detection of X-ray Absorption Associated with a Damped Lyman Alpha System
Jill Bechtold, Aneta Siemiginowska, Thomas L. Aldcroft +2
We have observed three quasars, PKS 1127-145, Q 1331+171 and Q0054+144, with the ACIS-S aboard the Chandra X-ray Observatory, in order to measure soft X-ray absorption associated w…
A Chandra Survey of Broad Absorption Line Quasars
Paul J. Green, Thomas L. Aldcroft, Smita Mathur +2
We have carried out a survey with the Chandra X-ray Observatory of a sample of 10 optically bright broad absorption line (BAL) QSOs. Eight out of ten sources are detected. The 6 br…
