The Low-z Intergalactic Medium. III. HI and Metal Absorbers at z<0.4
Charles W. Danforth, J. Michael Shull
We conduct an ultraviolet (HST and FUSE) spectroscopic survey of HI (Lyman lines) and seven metal ions (OVI, NV, CIV, CIII, SiIV, SiIII, FeIII) in the low-redshift intergalactic me…

Critical Metallicities for Second-Generation Stars
J. Michael Shull
The first massive stars may influence the formation of second-generation stars, in part by their metal enrichment of the surrounding gas. We investigate the "critical metallicity",…

The Metallicity of Intergalactic Gas in Cosmic Voids
John T. Stocke, Charles W. Danforth, J. Michael Shull +2
We have used the Hubble/STIS and FUSE archives of ultraviolet spectra of bright AGN to identify intergalactic Lya absorbers in nearby (z < 0.1) voids. From a parent sample of 651 L…
