Searches for Low-Metallicity Galaxies and Preliminary Results from the KPNO International Spectroscopic Survey
Abstract
Description
Searches for low-metallicity galaxies are reviewed, focusing mainly on efforts to discover systems that are relevant for use in measuring the primordial helium abundance. Wide-field objective-prism surveys for blue or emission-line galaxies have played a major role in this field. Previous surveys and search techniques are highlighted. Preliminary results from our new survey for emission-line galaxies, the KPNO International Spectroscopic Survey (KISS), are presented. KISS is substantially deeper than previous photographic surveys, and represents the next generation of wide-field slitless spectroscopic surveys.
