Outflow Properties of Star-forming Galaxies at 2 from the MOSDEF Survey
Abstract
The MOSFIRE Deep Evolution Field (MOSDEF) survey is using the MOSFIRE instrument on the Keck I telescope to obtain more than 1700 rest-frame optical spectra of galaxies from redshift 1.5 to 3.6 over four years. We are using the first 200 spectra to investigate the prevalence of outflows measured in emission in broad components of the nebular emission lines. We create stacks of galaxies based on properties such as star formation rate, stellar mass, and star formation rate surface density (controlling for the presence of AGNs) in order to study how outflow strength depends on these factors. Additionally, we will stack spectra by redshift to understand how outflows change over time. We will present the results of two component (narrow and broad) fits to the nebular emission and compare to theoretical predictions of outflow efficiency.
