TL;DR: In this paper, the authors present a catalog of 5039 broad absorption line (BAL) quasars (QSOs) in the Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5) QSO catalog that have absorption troughs covering a continuous velocity range ≥2000 km s 1.

X-ray Insights into the Nature of PHL 1811 Analogs and Weak Emission-line Quasars: Unification with a Geometrically Thick Accretion Disk?
Bin Luo,W. N. Brandt,Patrick B. Hall,Jianfeng Wu,Scott F. Anderson,Gordon P. Garmire,Robert R. Gibson,Richard M. Plotkin,Gordon T. Richards,Donald P. Schneider,Ohad Shemmer,Yue Shen +11 more
TL;DR: In this paper, an X-ray and multi-wavelength study of 33 weak emission-line quasars and 18 supernova analogs of the extreme WLQ, PHL 1811, at z ≈ 0.5 −2.9.

TL;DR: It is reported that deficiency in SETDB1, a histone methyltransferase that mediates the trimethylation of histone H3 at lysine 9, participates in the pathogenesis of IBD and targeting necroptosis of intestinal stem cells may represent an approach for the treatment of severe IBD.
Journal ArticleDOI

Brendan P. Miller,Brendan P. Miller,Brendan P. Miller,W. N. Brandt,Donald P. Schneider,Robert R. Gibson,A. T. Steffen,Jianfeng Wu +7 more
TL;DR: In this article, the authors present the results of an investigation into the X-ray properties of radio-intermediate and radio-loud quasars (RIQs and RLQs, respectively).
Journal ArticleDOI
A Population of X-Ray Weak Quasars: PHL 1811 Analogs at High Redshift
Jianfeng Wu,W. N. Brandt,Patrick B. Hall,Robert R. Gibson,Gordon T. Richards,Donald P. Schneider,Ohad Shemmer,Dennis W. Just,Sarah J. Schmidt +8 more
TL;DR: In this paper, Chandra and XMM-Newton observations of a sample of 10 type 1 quasars selected to have unusual UV emission-line properties (weak and blueshifted high-ionization lines; strong UV Fe emission) similar to those of PHL 1811, a confirmed intrinsically X-ray weak quasar.
