Dust and Diffuse Interstellar Bands in the z_a = 0.524 Absorption System toward AO 0235+164
V. T. Junkkarinen, Ross D. Cohen, E. A. Beaver +3
We present new HST STIS NUV-MAMA and STIS CCD observations of the BL Lac object AO 0235+164 and the intervening damped Ly alpha (DLA) line at z_a = 0.524. The line profile gives N(…
Variability Tests for Intrinsic Absorption Lines in Quasar Spectra
Desika Narayanan, Fred Hamann, Tom Barlow +4
Quasar spectra have a variety of absorption lines whose origins range from energetic winds expelled from the central engines to unrelated, intergalactic clouds. We present multi-ep…
UV Imaging Polarimetry of the peculiar Seyfert 2 galaxy Mrk 477
Makoto Kishimoto, Laura E. Kay, Robert Antonucci +3
We present the results of UV imaging polarimetry of the Seyfert 2 galaxy Mrk 477 taken by the Faint Object Camera onboard the Hubble Space Telescope (HST). From a previous HST UV i…
UV Imaging Polarimetry of the Seyfert 2 Galaxy Mrk 3
Makoto Kishimoto, Laura E. Kay, Robert Antonucci +3
We present UV imaging polarimetry data of the Seyfert 2 galaxy Mrk 3 taken by the Hubble Space Telescope. The polarized flux is found to be extended to ~1 kpc from the nucleus, and…
HST UV and Keck HIRES Spectra of BAL Quasars
V. Junkkarinen, R. D. Cohen, T. A. Barlow +1
In the analysis of broad absorption line (BAL) quasar spectra, Keck HIRES spectra are a useful complement to lower resolution HST and ground based spectra. The HIRES spectra provid…
Discovery of a 2 Kpc Binary Quasar
G. A. Shields, V. Junkkarinen, E. A. Beaver +4
LBQS 01032753 is a binary quasar with a separation of only 0.3 arcsec. The projected spacing of 2.3 kpc at the distance of the source (z = 0.848) is much smaller than that of an…
