Abstract

While many of the characteristics of the star-forming galaxies now being surveyed in large numbers at z = 2 - 3 are reminiscent of elliptical galaxies and bulges, the progenitors of today’s spiral disks have proved more difficult to identify, probably because they were smaller and fainter at these early epochs. It will be many years yet before we can probe interstellar Hi gas in 21 cm emission at these redshifts, but the HII regions of UV-bright galaxies will soon be mapped on kpc-scale from the ground with new instrumentation designed to work with laser-guided adaptive optics. This will be our best chance to measure disk-like rotation at high redshift.
