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< 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.
