Kinematics of Distant Milky Way Halo RR Lyrae Stars out to 160 kpc

open access: yesThe Astrophysical Journal
We present a kinematical study of the outer halo ( r _GC  ∼ 60–160 kpc) of the Milky Way (MW) based on spectroscopy of 55 RR Lyrae stars using the Echelle Spectrograph and Imager instrument on the Keck II telescope.
