Reconstructing the orbits of Milky Way dwarf galaxies: An LMC perspective
Alberto Manuel MartÃnez-GarcÃa, Andrés del Pino, Roeland P. van der Marel +14
The orbital histories of the dwarf satellites of the Milky Way (MW) are key to understanding their evolution and placing their present-day properties in a dynamical context. We pre…

The Orbits of Isolated Dwarfs in the Local Group from New 3D Kinematics: Constraints on First Infall, Backsplash, and Quenching Mechanisms
Paul Bennet, Ekta Patel, Sangmo Tony Sohn +8
It is commonly supposed that quenched field dwarfs near the edge of the Local Group (LG) are backsplash galaxies, having previously orbited within the Milky Way (MW) or M31's viria…
