摘要:
Understanding the nature and future evolution of star-forming galaxies found at2<z<5requires a thorough knowledge of the star formation process locally. The KPNO International Spectroscopic Survey (KISS) is a wide-field survey for extragalactic emission-line objects being carried out with the Burrell Schmidt at Kitt Peak. We have discovered approximately 1100 emission-line galaxies (ELGs) in a survey area of 68 sq. degrees (16.6 galaxies per square degree). These ELGs were identified via their H&agr; flux and have been used to measure the star formation rate (SFR) density of the local universe. We find a SFR density approximately equal to that found by Gallego &etal; (1995). We note, however, that our survey is incomplete for galaxies withEW(H&agr;)<25&hthinsp;Åimplying that thetotallocal SFR density is higher than this value. ©1999 American Institute of Physics.
