Dynamical Friction by Coupled Dark Energy

The Astrophysical Journal
In this paper, we examine dynamical friction at galactic scales within the framework of coupled dark energy (CDE). This model posits dark energy as coupled quintessence, which maintains a minimal coupling to gravity but interacts nonminimally with both ...

HSTPROMO Internal Proper-motion Kinematics of Dwarf Spheroidal Galaxies. I. Velocity Anisotropy and Dark Matter Cusp Slope of Draco

The Astrophysical Journal
We analyze four epochs of Hubble Space Telescope imaging over 18 yr for the Draco dwarf spheroidal galaxy. We measure precise proper motions for hundreds of stars and combine these with existing line-of-sight (LOS) velocities.
