Tidally induced velocity gradients in the Milky Way dwarf spheroidal satellites
We present a kinematic study of six dwarf spheroidal galaxies (dSph) satellites of the Milky Way (MW), namely Carina, Draco, Fornax, Sculptor, Sextans, and Ursa Minor. We combine proper motions (PMs) from the Gaia Data Release 3 (DR3) and line-of-sight velocities (v los) from the literature to derive their 3D internal kinematics and to study the
