Galactic Outflows and Their Correlations with Galaxy Properties at 0.8 < Z < 1.6

Abstract

Out ows have been shown to be ubiquitous in galaxies between z = 1 and z=2, and many models and observations have attempted to correlate the absorption line properties of these out ows with morphological characteristics of their host galaxies. In this study, we examined the spectra of 71 galaxies with redshifts 1 particular attention to the FeII and MgII absorption lines. We plotted the equivalent width, velocity, and maximum velocity of the absorption features against various physical properties of the galaxies, obtained from catalogues created by Skelton et al., (2014) and van der Wel et al., (2012). We conrmed the presence of out ows in our galaxy sample, and found a signicant trend between the equivalent width and star formation rate - out owing gas has stronger absorption lines in galaxies with higher star formation rates.
