Chlorine in the Galactic ISM: Revised f-values with FUSE and STIS
P. Sonnentrucker, S. D. Friedman, D. G. York
Cl I is the atomic species most directly coupled to molecular hydrogen due to its chemistry. Its weakest lines are thereby probably the best tracer of optically thick H2 components…

This paper describes the Third Data Release of the Sloan Digital Sky Survey (SDSS). This release, containing data taken up through June 2003, includes imaging data in five bands ov…
The Microlensing Planet Finder: Completing the Census of Extrasolar Planets in the Milky Way
D. P. Bennett, I. Bond, E. Cheng +21
The Microlensing Planet Finder (MPF) is a proposed Discovery mission that will complete the first census of extrasolar planets with sensitivity to planets like those in our own sol…
The Second Data Release of the Sloan Digital Sky Survey
K. Abazajian et al.
The Sloan Digital Sky Survey has validated and made publicly available its Second Data Release. This data release consists of 3324 square degrees of five-band (u g r i z) imaging d…
A Study of the Reionization History of Intergalactic Helium with FUSE and VLT
W. Zheng, G. A. Kriss, J. -M. Deharveng +8
We obtained high-resolution VLT and FUSE spectra of the quasar HE2347-4342 to study the properties of the intergalactic medium between redshifts z=2.0-2.9. The high-quality optical…
The Deuterium-to-Hydrogen Ratio in a Low-Metallicity Cloud Falling onto the Milky Way
