Streaming motion in Leo I
Bodhisattva Sen, Moulinath Banerjee, Michael Woodroofe +2
Whether a dwarf spheroidal galaxy is in equilibrium or being tidally disrupted by the Milky Way is an important question for the study of its dark matter content and distribution.…
Stellar Velocities in the Carina, Fornax, Sculptor and Sextans dSph Galaxies: Data from the Magellan/MMFS Survey
Matthew G. Walker, Mario Mateo, Edward Olszewski
We present spectroscopic data for individual stars observed from 2004 March through 2008 August as part of our Michigan/MIKE Fiber System (MMFS) survey of four dwarf spheroidal (dS…
Systemic Proper Motions of Milky Way Satellites from Stellar Redshifts: the Carina, Fornax, Sculptor and Sextans Dwarf Spheroidals
Matthew G. Walker, Mario Mateo, Edward W. Olszewski
The transverse motions of nearby dwarf spheroidal (dSph) galaxies contribute line-of-sight components that increase with angular distance from the dSph centers, inducing detectable…
A common mass scale for satellite galaxies of the Milky Way
Louis E. Strigari, James S. Bullock, Manoj Kaplinghat +4
The Milky Way has at least twenty-three known satellite galaxies that shine with luminosities ranging from about a thousand to a billion times that of the Sun. Half of these galaxi…
The Velocity Dispersion Profile of the Remote Dwarf Spheroidal Galaxy Leo I: A Tidal Hit and Run?
Mario Mateo, Edward W. Olszewski, Matthew G. Walker
(abridged) We present kinematic results for a sample of 387 stars located near Leo I based on spectra obtained with the MMT's Hectochelle spectrograph near the MgI/Mgb lines. We es…
Velocity Dispersion Profiles of Seven Dwarf Spheroidal Galaxies
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +4
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 68…
