Mg-II Gas Clouds and Galactic Evolution
Abstract
The DESI project is a proposed five-year project that plans to create a detailed three-dimensional map of the Universe in order to study the nature of dark energy. To this end the DESI team will measure the spectra of over 30 million galaxies and quasars covering an area of more than 14,000 deg^2. Using this extensive map of the Universe we are able to use the spectra of over 18.7 million objects released in DESI’s Data Release 1 to explore galactic evolution. To do this we will look for galaxies with nearby Mg-II gas clouds and investigate their physical properties. For example, looking for correlations between absorption strength of the Mg-II system versus distance to a nearby galaxy, as well as the specific star formation rate of the galaxies near a Mg-II gas cloud. The results of this research will serve as a supporting body of evidence for current ideas of how galaxies evolve.
