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