Systematic Search for Extremely Metal-poor Galaxies in the Sloan Digital Sky Survey
We carry out a systematic search for extremely metal-poor (XMP) galaxies in the spectroscopic sample of Sloan Digital Sky Survey (SDSS) data release 7 (DR7). The XMP candidates are found by classifying all the galaxies according to the form of their spectra in a region 80 Å wide around Hα. Due to the data size, the method requires an automatic
