Galactic Mass Estimates Using Dwarf Galaxies as Kinematic Tracers

New mass estimates and cumulative profiles with Bayesian credible regions (c.r.) for the Milky Way (MW) are found using Galactic Mass Estimator (GME) code dwarf galaxy (DG) kinematic data from multiple sources. GME takes a hierarchical approach to simultaneously estimate true positions velocities of DGs, their velocity anisotropy, model parameters Galaxy's total gravitational potential. In this study, we incorporate meaningful prior information past studies simulations. The distributions physical informed by results Eadie & Juric (2019), which used globular clusters instead as well subhalo Ananke Gaia-like surveys Feedback Realistic Environments-2 (Fire-2) cosmological simulations (see Sanderson et al. 2020). Using DGs beyond 45 kpc, report median 95% c.r $r_{200}$ = 212.8 (191.12,238.44) enclosed $M_{200}$ 1.19 (0.87,1.68)$\times10^{12}M_{\odot}$ (adopting $\Delta_c=200$). Median at specific radii also reported (e.g., $M(<50\text{ kpc})=0.52\times10^{12}M_{\odot}$ $M(100\text{ kpc})=0.78\times10^{12}M_{\odot}$). Estimates comparable other recent GAIA DR2 but notably different (2019). We perform sensitivity analysis investigate whether individual and/or more massive Large Magellanic Cloud (LMC) on order $10^{11}M_{\odot}$ may be affecting our estimates. find possible supporting evidence idea that some affected LMC not in equilibrium MW.
