However, the interpretation of Mg II remains confusing, due to resonant trapping and re-emission of the photons, analogous to Lyman Alpha. Therefore, in this paper, we present new MMT Blue Channel Spectrograph observations of Mg II for a sample of 10 Green Pea galaxies at z~0.2-0.3, where Lyman Alpha was previously observed with the Cosmic Origins Spectrograph on Hubble Space Telescope.
