Relating Lyman alpha emission line properties to rest UV morphology

Lyman alpha is the strongest (and often only) emission line detected from galaxies in the distant Universe (z>3). Its profile is modified by resonant scattering from neutral hydrogen and therefore measurements of this profile may indicate the presence of outflows or winds. It has recently been suggested that Lyman alpha emission line morphology may correlate with the rest-frame ultraviolet morphology of distant galaxies. We have been studying the reliability and further implications of this suggestion, and exploring the minimum instrumental resolutions required to precisely measure any relation in both spatial and spectral information. In this poster, we present initial results from this study, and discuss the general applicability of morphological studies to yield insights into outflow behaviour.
