A Magellan M2FS Spectroscopic Survey of Galaxies at 5.5<z<6.8: Program Overview and a Sample of the Brightest Lyman-alpha Emitters
Linhua Jiang, Yue Shen, Fuyan Bian +16
We present a spectroscopic survey of high-redshift, luminous galaxies over four square degrees on the sky, aiming to build a large and homogeneous sample of Ly emitters (LAEs) a…
Magellan/M2FS Spectroscopy of Galaxy Clusters: Stellar Population Model and Application to Abell 267
Evan Tucker, Matthew G. Walker, Mario Mateo +4
We report the results of a pilot program to use the Magellan/M2FS spectrograph to survey the galactic populations and internal kinematics of galaxy clusters. For this initial study…
The binary fraction of stars in dwarf galaxies: the case of Leo II
Meghin Spencer, Mario Mateo, Matthew Walker +4
We combine precision radial velocity data from four different published works of the stars in the Leo II dwarf spheroidal galaxy. This yields a dataset that spans 19 years, has 14…
A multi-epoch kinematic study of the remote dwarf spheroidal galaxy Leo II
Meghin Spencer, Mario Mateo, Matthew Walker +1
We conducted a large spectroscopic survey of 336 red giants in the direction of the Leo II dwarf galaxy using Hectochelle on the MMT, and conclude that 175 of them are members base…
SMASH - Survey of the MAgellanic Stellar History
David L. Nidever, Knut Olsen, Alistair R. Walker +36
The Large and Small Magellanic Clouds (LMC and SMC) are unique local laboratories for studying the formation and evolution of small galaxies in exquisite detail. The Survey of the…
