The Galaxy Environment of O VI Absorption Systems
John T. Stocke, Steven V. Penton, Charles W Danforth +3
We combine a FUSE sample of OVI absorbers (z < 0.15) with a database of 1.07 million galaxy redshifts to explore the relationship between absorbers and galaxy environments. All 37…
Critical Metallicity and Fine-Structure Emission of Primordial Gas Enriched by the First Stars
Fernando Santoro, J. Michael Shull
The influence of the first stars on the formation of second-generation objects at high redshift may be determined, in part, by their metal enrichment of surrounding gas. At a criti…
The Low-z Intergalactic Medium. II. LyB, OVI, and CIII Forest
Charles W. Danforth, J. Michael Shull, Jessica L. Rosenberg +1
We present the results of a large survey of HI, OVI, and CIII absorption lines in the low-redshift (z<0.3) intergalactic medium (IGM). We begin with 171 strong Lyalpha absorption l…
Molecular Hydrogen in Infrared Cirrus
Kristen Gillmon, J. Michael Shull
We combine data from our recent FUSE survey of interstellar molecular hydrogen absorption toward 50 high-latitude AGN with COBE-corrected IRAS 100 micron emission maps to study the…
A FUSE Survey of Interstellar Molecular Hydrogen toward High-Latitude AGN
Kristen Gillmon, J. Michael Shull, Jason Tumlinson +1
We report results from a FUSE survey of interstellar molecular hydrogen (H2) along 45 sight lines to AGN at high Galactic latitudes (|b| > 20 degrees). Most (39 of 45) of the sight…
The EUV variability of the luminous QSO HS 1700+6416
D. Reimers, H. -J. Hagen, J. Schramm +2
We report on the first observations of variations in UV (intrinsic EUV 330 A) flux of the luminous QSO HS 1700+6416 (z=2.72) over a decade. The amplitude of variations increases fr…
