Signatures of dark subhaloes in dwarf spheroidal galaxies: II. Transient and localised kinematic features

We use controlled N-body simulations to investigate whether dark matter subhaloes leave detectable signatures in the internal kinematics of dwarf spheroidal galaxies. At each snapshot, we fit a velocity distribution function to stellar line-of-sight velocities and proper motions, construct normalised residual fields fo...
