Executive Summary...

What is dark energy How does its equation of state vary as a function of time How do galaxies form What is the nature of dark matter on galactic scales What formation mechanisms result in the observed structure of our Galaxy Why is our Galaxy different in structure from other local group members How does galaxy formation and evolution depend on the formation and evolution of large scale structure How was the Universe reionized What mechanisms govern the creation and dispersal of "metals" in the Universe Such are some of the key questions facing today's science of astronomy. The recent Gemini ASPEN workshop (Scientific Horizons at the Gemini Observatory Exploring a Universe of Matter, Energy and Life) identified many of these questions as key areas in which the Gemini telescopes should be engaged over the coming decades. A new facility capable of taking detailed spectroscopy of millions of objects in the Universe overcomes the statistical complexity of the Universe and allows us to answer these fundamental questions. In this document we present the scientific case, technical feasibility, and estimated cost of a wide-field, fiber-fed, multiobject spectrograph (WFMOS) for the Gemini/Subaru observatory. This study is the result of a call by Gemini to examine such an instrument as an outcome of the ASPEN meeting. The Gemini observatory is exploring the possibility that this facility may actually be implemented on the Subaru telescope, but shared between the Gemini and Subaru communities in exchange for Subaru access to other key instruments on Gemini. WFMOS provides Gemini/Subaru w...
