Brad M. S. Hansen,Jay Anderson,James Brewer,Aaron Dotter,Gregory G. Fahlman,Jarrod R. Hurley,Jasonjot S. Kalirai,Ivan R. King,David Reitzel,Harvey B. Richer,R. Michael Rich,Michael M. Shara,Peter B. Stetson +12 more
TL;DR: The results of a deep Hubble Space Telescope (HST) exposure of the nearby globular cluster NGC 6397, focusing on the cluster's white dwarf cooling sequence, are presented in this paper.
Journal ArticleDOI
The metal-poor halo of the andromeda spiral galaxy (m31)
Jasonjot S. Kalirai,Karoline M. Gilbert,Puragra Guhathakurta,Steven R. Majewski,James C. Ostheimer,R. Michael Rich,Michael C. Cooper,David Reitzel,Richard J. Patterson +8 more
TL;DR: In this paper, the authors presented spectroscopic observations of red giant branch (RGB) stars over a large expanse in the halo of the Andromeda spiral galaxy (M31), acquired with the DEIMOS instrument on the Keck II 10 m telescope.
Journal ArticleDOI
A new method for isolating M31 red giant stars : The discovery of stars out to a radial distance of 165 kpc
Karoline M. Gilbert,Puragra Guhathakurta,Jasonjot S. Kalirai,R. Michael Rich,Steven R. Majewski,James C. Ostheimer,David Reitzel,A. Javier Cenarro,A. Javier Cenarro,Michael C. Cooper,C. Luine,Richard J. Patterson +11 more
TL;DR: In this paper, a method for isolating a clean sample of red giant branch stars in the outer regions of M31 is presented, based on an ongoing spectroscopic survey using the DEIMOS instrument on the Keck II 10 m telescope.
Journal ArticleDOI
Kinematics and Metallicity of M31 Red Giants: The Giant Southern Stream and Discovery of a Second Cold Component at R = 20 kpc
Jasonjot S. Kalirai,Puragra Guhathakurta,Karoline M. Gilbert,David Reitzel,S. R. Majewski,R. M. Rich,Michael C. Cooper +6 more
TL;DR: In this paper, spectroscopic observations of red giant branch (RGB) stars in the Andromeda spiral galaxy (M31), acquired with the DEIMOS instrument on the Keck II 10-m telescope.
Journal ArticleDOI
Deep advanced camera for surveys imaging in the globular cluster NGC 6397: The cluster color-magnitude diagram and luminosity function
Harvey B. Richer,Aaron Dotter,Jarrod R. Hurley,Jay Anderson,Ivan R. King,D. Saul Davis,Gregory G. Fahlman,Brad M. S. Hansen,Jasonjot S. Kalirai,Nathaniel Paust,R. Michael Rich,Michael M. Shara +11 more
TL;DR: The color-magnitude diagram (CMD) from deep Hubble Space Telescope imaging in the globular cluster NGC 6397 was presented in this article, showing that the main-sequence stars appeared to terminate close to the location in the CMD of the hydrogen burning limit predicted by two independent sets of stellar evolution models.
