Induced star formation and morphological evolution in very high redshift radio galaxies
Wil van Breugel, A. Stanford, A. Dey +5
Near-infrared, sub-arcsecond seeing images obtained with the W. M. Keck I Telescope of show strong evolution at rest--frame optical} wavelengths in the morphologies of high redshif…

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…
