[43.17] An H\alpha Objective-Prism Survey in the NDWFS Böotes Field

C. Gronwall (Penn State U.), J.J. Salzer, A. Jangren (Wesleyan U.)

We present preliminary results of an objective-prism survey for nearby emission-line galaxies (ELGs) in the NOAO Deep Wide Field Survey (NDWFS) Böotes Field. This survey is part of the KPNO International Spectroscopic Survey (KISS) collaboration which has surveyed approximately 150 square degrees for H\alpha emission-line galaxies out to z=0.1. KISS is the first purely digital objective-prism survey, and it extends previous photographic surveys to much fainter flux limits. Results for the first two survey strips have provided a large sample of 2157 ELG candidates in 128 square degrees or 16.9 per square degree. We have discovered ~150 additional ELG candidates in the NDWFS Böotes field, and follow-up spectroscopy for this sample is scheduled. We present magnitude, color, redshift, and spatial distributions of this sample based on the survey data. In addition, we present samples of our recently acquired follow-up spectra. We also discuss possible science projects enabled by the combination of our KISS data with multiwavelength surveys in the Böotes field. In particular, because our sample is selected via H\alpha emission, it is ideal for studying star formation in the local universe. We plan to combine our H\alpha data with the extensive multi-wavelength data available in this field to better calibrate the various star-formation rate indicators used to study star formation in the distant universe. The full data set will be made available to the community to ensure the highest possible use of the data for a variety of projects involving the NWDFS.
