TL;DR: In this paper, the DEIMOS multi-object spectrograph on the Keck II 10 m telescope was used to conduct a spectroscopic survey of red giant branch stars in the outskirts of M31.
Journal ArticleDOI
Life at the Periphery of the Local Group: the kinematics of the Tucana Dwarf Galaxy
TL;DR: In this paper, the authors used the VLT/FORS2 spectrograph in multi-object mode to measure the velocities of 23 individual Red Giant Branch stars in and around Tucana using the Ca triplet absorption lines.
Journal ArticleDOI

TL;DR: In this article, the discovery of a new satellite of the Milky Way in the constellation of Bootes at a distance of 60 kpc was reported, which makes it one of the faintest galaxies known.
Journal ArticleDOI
Using the Ca II Triplet to Trace Abundance Variations in Individual Red Giant Branch stars in Three Nearby Galaxies
TL;DR: In this article, the authors measured the equivalent widths of the two strongest Ca II triplet lines to determine metal abundances for a sample of Red Giant Branch stars, selected from ESO-NTT optical (I, V-I) photometry of three nearby, Local Group, galaxies.
