Galactic Outflows and Their Correlation with Galaxy Properties at 0.8 < z < 1.6

摘要

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< z<2, paying.;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.
