Mapping the Outer Edge of the Milky Way’s Dark Matter Halo Using LSST

David Gonzalez

Over its ten year mission, Rubin Observatory’s Legacy Survey of Space and Time (LSST) will gather enough data to see stars much fainter than previously observed in the southern sky, including time domain. This makes it an ideal survey with which to discover RR Lyrae stars in regions of our Galaxy not yet explored (and beyond - up to 700kpc away!)  and detect their periods for faint. We can use the period-luminosity relationship to estimate their distances and build a map of to the very edge our Galaxy’s dark matter halo. This project explores what we might see using simulated data sets.
