Properties and Origin of the High-Velocity Gas Toward the Large Magellanic Cloud
N. Lehner, L. Staveley-Smith, J. C. Howk
In the spectra of 139 early-type Large Magellanic Cloud (LMC) stars observed with FUSE and with deep radio Parkes HI 21-cm observations along those stars, we search for and analyze…
Strong z~0.5 O VI Absorption Toward PKS 0405-123: Implications for Ionization and Metallicity of the Cosmic Web
J. Christopher Howk, Joseph S. Ribaudo, Nicolas Lehner +2
We present observations of the O VI system at z_abs = 0.495096 toward PKS 0405-123 (z_em = 0.5726) obtained with FUSE and STIS. In addition to strong O VI, with log N(O VI) = 14.47…
Probing feedback in protogalaxies: Multiphase gas in a DLA at z~2.4
N. Lehner, J. C. Howk, J. X. Prochaska +1
We investigate the physical processes occuring in the multiphase gas of a damped Lyαsystem (DLA). We base our analysis on a high quality Keck HIRES spectrum of the QSO J1211+0422 i…
The High Velocity Gas toward Messier 5: Tracing Feedback Flows in the Inner Galaxy
William F. Zech, Nicolas Lehner, J. Christopher Howk +2
We present Far Ultraviolet Spectroscopic Explorer (FUSE) and Space Telescope Imaging Spectrograph (STIS E140M) observations of the post-asymptotic giant branch star ZNG 1 in the gl…
Metallicity and Physical Conditions in the Magellanic Bridge
N. Lehner, J. C. Howk, F. P. Keenan +1
We present a new analysis of the diffuse gas in the Magellanic Bridge (RA>3h) based on HST/STIS E140M and FUSE spectra of 2 early-type stars lying within the Bridge and a QSO behin…
A High-Resolution Survey of Low-Redshift QSO Absorption Lines: Statistics and Physical Conditions of O VI Absorbers
Todd M. Tripp, Kenneth R. Sembach, David V. Bowen +5
Using high-resolution UV spectra of 16 low-z QSOs, we study the physical conditions and statistics of O VI absorption in the IGM at z < 0.5. We identify 51 intervening (z_{abs} <<…
