Resolution Data

This is a study of the Lyman edge region in the spectra of eleven high redshift quasars. We present large aperture, low resolution data designed to detect broadened Lyman edge absorption predicted by thermal models of the Big Blue Bump continuum component. We also present high resolution data on the edge regions and the Lyman alpha emission line for nine of the objects. We show some partial absorption edges and discuss whether or not they can be interpreted as support for the accretion disk model.

Emission Line Profile

Superwind galaxies at high-redshift are now considered to be the important clue for understanding the interaction and evolution of both galaxies and intergalactic matter. In order to improve our knowledge of superwind galaxies at high redshift, a large sample of superwind candidates is needed. During the course of our new search for Lyman alpha emitters at z = 5.7, we have found a candidate superwind galaxy, LAE J1044-0130, at z = 5.69. The emission-line profile of this object is asymmetric, showing excess red-wing emission and the observed broad line width (= 340 km/s). In this poster, we report detailed observed properties of LAE J1044-0130 as an example of a superwind galaxy.
