The Interaction of 3C401 with the Surrounding Intracluster Medium
Christopher S. Reynolds, Laura W. Brenneman, John T. Stocke
We present an observation of the radio-galaxy 3C401 and the surrounding intracluster medium (ICM) of its host galaxy cluster by the Chandra X-ray Observatory. This luminous radio-g…
The Hot Intergalactic Medium - Galaxy Connection: Two Strong Absorbers in the Sightline Toward PG 1211+143
Jason Tumlinson, J. Michael Shull, Mark L. Giroux +1
We present HST/STIS and FUSE spectra of the QSO PG 1211+143 (z_em = 0.081) and a galaxy survey of the surrounding field. This sightline shows two strong intergalactic absorption sy…
Absorption Line Study of Halo Gas in NGC 3067 Toward the Background Quasar 3C 232
Brian A. Keeney, Emmanuel Momjian, John T. Stocke +2
We present new H I 21 cm absorption data and ultraviolet spectroscopy from HST/STIS of the QSO/galaxy pair 3C 232/NGC 3067. The QSO sightline lies near the minor axis and 1.8 arcmi…
The Baryon Content of the Local Intergalactic Medium
John T. Stocke, J. Michael Shull, Steven V. Penton
We describe our surveys of low column density Lyman-alpha absorbers [N(HI) = 10^(12.5-16.0) cm^-2], which show that the warm photoionized IGM contains 30% of all baryons at z < 0.1…
BL Lac evolution revisited
Anna Wolter, Francesca Cavallotti, John T. Stocke +1
BL Lac objects are an elusive and rare class of active galactic nuclei. For years their evolutionary behavior has appeared inconsistent with the trend observed in the population of…
BL Lac X-ray Spectra: simpler than we thought
Eric S. Perlman, Timothy Daugherty, Anuradha Koratkar +10
We report results from {\it XMM-Newton} observations of thirteen X-ray bright BL Lacertae objects, selected from the {\it Einstein} Slew Survey sample. The spectra are generally we…
