The Largest Sample of Extreme Emission-Line Galaxies
Abstract
The importance of low-mass, star-forming galaxies in the process of galaxy formation cannot be understated. Recent studies point to these objects as the leading candidates responsible for the reionization of the Universe, they are the building blocks of the larger galaxies in the present day and they are perfect laboratories to study the effect of star-formation feedback on galaxy evolution. The most efficient way of selecting these galaxies is by identifying emission lines in their spectra. Broadband selection of emission line galaxies (ELGs) has recently emerged as a viable technique that circumvents the short-comings of traditional selection techniques such as narrow band imaging and spectroscopy. If the line emission is strong enough, it can contribute significantly to the broadband flux, allowing us to select ELGs by their broadband colors. In this poster, we present the results of a search for extreme ELGs in the low redshift Universe (z ~ 0.3 - 0.7), over 5000 square degrees and down to two magnitudes fainter than what has previously been done.
