Journal ArticleDOI
X-ray studies of quasars with the Einstein Observatory. II
G. Zamorani,J. P. Henry,Tommaso Maccacaro,Harvey Tananbaum,A. M. Soltan,Y. Avni,J. Liebert,John T. Stocke,P. A. Strittmatter,R.J. Weymann,M.G. Smith,James J. Condon +11 more
TL;DR: In this paper, the positions, fluxes and luminosities of 35 known quasars were observed by the Einstein high-resolution imaging detector and the imaging proportional counter, with evidence of very little cold gas absorption.
Journal ArticleDOI
The Properties of the X-Ray-Selected EMSS Sample of BL Lac Objects
TL;DR: In this article, the authors presented updated and complete radio, optical and X-ray data for BL Lacs in the Einstein Medium Sensitivity Survey (EMSS), and they confirmed negative evolution for XBLs, especially for more extreme high-energy-peaked BL Lac (XBL) samples.
Journal ArticleDOI
Ten new BL Lacertae objects discovered by an efficient X-ray/radio/optical technique
Jonathan F. Schachter,John T. Stocke,Eric S. Perlman,Martin Elvis,Ron Remillard,Arno Granados,Jane Luu,John P. Huchra,Roberta M. Humphreys,C. Megan Urry,John F. Wallin +10 more
TL;DR: In this paper, the authors reported the discovery of ten BL Lac objects in the Einstein IPC Slew Survey by means of X-ray/radio versus Xray/optical color-color diagrams and confirming optical spectroscopy.
Journal ArticleDOI
Absorption-Line Detections of $10^{5-6}$ K Gas in Spiral-Rich Groups of Galaxies
John T. Stocke,Brian A. Keeney,Charles W. Danforth,David Syphers,H. Yamamoto,J. M. Shull,James C. Green,Cynthia S. Froning,Blair D. Savage,Bart P. Wakker,T. S. Kim,Emma V. Ryan-Weber,Glenn G. Kacprzak +12 more
TL;DR: In this article, the authors used the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST) for a high signal-to-noise survey of 14 bright QSOs.
Journal ArticleDOI
The medium sensitivity survey - A new sample of X-ray sources with optical identifications and the revised extragalactic log N-log S
Isabella M. Gioia,Tommaso Maccacaro,Rudolph E. Schild,John T. Stocke,James Liebert,I. J. Danziger,D. Kunth,J. Lub +7 more
TL;DR: In this article, an extension of the MSS 1 on the basis of an analysis of new fields obtained with the aid of the Imaging Proportional Counter (IPC) on board the Einstein Observatory was also undertaken.
