Inferring the Total Mass of Galaxy Halos Using Photometry
Galaxy size, as defined as the radius at which the stellar surface density reaches $1~\mathrm{M}_\odot\,\mathrm{pc}^{-2}$ ($R_1$), has been shown to correlate more tightly with stellar mass than the effective radius. Cosmological simulations further predict a tight relation between $R_1$ and dark matter halo mass ($M_{...
