Evidence for Solar Metallicities in Massive Star‐forming Galaxies at z ≳ 2

Abstract

We present results of near-IR spectroscopic measurements of seven star-forming galaxies at 2.1 1.5) tails of current K-band-selected samples such as the K20 and Gemini Deep Deep surveys. Based in part on data obtained at the W. M. Keck Observatory, which is operated as a scientific partnership between the California Institute of Technology, the University of California, and NASA, and was made possible by the generous financial support of the W. M. Keck Foundation.
