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…

Keck Spectroscopy of Giant Arcs in Abell 2390
B. L. Frye, T. J. Broadhurst, H. Spinrad +1
We present new Keck observations of giant arcs in the cluster Abell 2390. High resolution two-dimensional spectra of two arcs show metal lines at z=4.040 +/- 0.005 with Lyman-alpha…

Spectroscopy of z>3 Lyman-limit Galaxies
Hyron Spinrad, Arjun Dey, Daniel Stern +1
We discuss the spectral character of Lyman-limit-selected, star-forming galaxies at z>3. The rest-frame UV spectra of these faint galaxies may show Ly-alpha in either absorption or…
