STIS Observations of He II Gunn-Peterson Absorption Toward Q0302-003
S. R. Heap, G. M. Williger, A. Smette +5
The ultraviolet spectrum (1145--1720A) of the distant quasar Q 0302--003 (z=3.286) was observed at 1.8A resolution with the Space Telescope Imaging Spectrograph aboard the Hubble S…

Limits on the star formation rates of z>2 damped Ly-alpha systems from H-alpha spectroscopy
Andrew J. Bunker, Stephen J. Warren, D. L. Clements +2
We present the results of a long-slit K-band spectroscopic search with CGS4 on UKIRT for H-alpha emission from the objects responsible for high-redshift (z > 2) damped Ly-alpha abs…
