Surveys and the Blazar Parameter Space
E. S. Perlman, P. Padovani, H. Landt +5
The rareness of blazars, combined with the previous history of relatively shallow, single-band surveys, has dramatically colored our perception of these objects. Despite a quarter-…
Astronomical Constraints on the Cosmic Evolution of the Fine Structure Constant and Possible Quantum Dimensions
C. L. Carilli, K. M. Menten, J. T. Stocke +6
We present measurements of absorption by the 21cm hyperfine transition of neutral hydrogen toward radio sources at substantial look-back times. These data are used in combination w…
Interstellar Gas and Star Formation Near the Peculiar Radio Galaxy NGC 4410A
Beverly J. Smith, Megan Donahue, John Stocke
We present new multi-wavelength data for the NGC 4410 galaxy group. This group contains the peculiar radio galaxy NGC 4410A, which has a distorted double-lobed radio structure. NGC…
Metal Abundances in the Magellanic Stream
Brad K. Gibson, Mark L. Giroux, Steven V. Penton +3
We report on the first metallicity determination for gas in the Magellanic Stream, using archival HST GHRS data for the background targets Fairall 9, III Zw 2, and NGC 7469. For Fa…
The Properties of the X-Ray-Selected EMSS Sample of BL Lac Objects
T. A. Rector, J. T. Stocke, E. S. Perlman +2
We present updated and complete radio, optical and X-ray data for BL Lacs in the Einstein Medium Sensitivity Survey (EMSS). The complete "M91" sample first presented in Morris et a…
FUSE Observations of the Low-Redshift Lyman-beta Forest
J. M. Shull, M. L. Giroux, S. V. Penton +10
We describe a moderate-resolution (20-25 km/s) FUSE study of the low-redshift intergalactic medium. We report on studies of 7 extragalactic sightlines and 12 Ly-beta absorbers that…
