We present stellar velocity dispersion profiles for seven Milky Way dwarf spheroidal (dSph) satellite galaxies. We have measured 8394 line-of-sight velocities (±2.5 km s) for 6804 stars from highresolution spectra obtained at the Magellan and MMT telescopes. We combine these new data with previously published velocities to obtain the largest available… CONTINUE READING
