Journal ArticleDOI
The keck low-resolution imaging spectrometer
J. B. Oke,Judith G. Cohen,Michael A. Carr,John Cromer,A. Dingizian,Frederick H. Harris,S. Labrecque,Richard Lucinio,W. A. Schaal,Harland W. Epps,J. Miller +10 more
TL;DR: The Low Resolution Imaging Spectrometer (LRIS) for the Cassegrain focus of the Keck 10-meter telescope on Mauna Kea is described in this paper, which has an imaging mode so it can also be used for taking direct images.
Journal ArticleDOI
New Insight on Galaxy Formation and Evolution From Keck Spectroscopy of the Hawaii Deep Fields
TL;DR: In this paper, the results of spectroscopic studies with the LRIS spectrograph on Keck of two of the Hawaii deep survey fields were presented, and the evolution of the rest-frame K-band luminosity function and its evolution with redshift were described.
Journal ArticleDOI
The Universal Stellar Mass-Stellar Metallicity Relation for Dwarf Galaxies
Evan N. Kirby,Judith G. Cohen,Puragra Guhathakurta,Lucy Cheng,James S. Bullock,Anna Gallazzi,Anna Gallazzi +6 more
TL;DR: In this paper, spectroscopic metallicities of individual stars in seven gas-rich dwarf irregular galaxies (dIrrs) were analyzed and it was shown that dIrrs obey the same mass-metallicity relation as the dwarf spheroidal (dSph) satellites of both the Milky Way and M31: Z_* ∝ M_*^(0.30±0.02).
Journal ArticleDOI
