Tucson Workshop on Next Generation Wide Field MultiObject Spectroscopy

Tucson, AZ
11 & 12 October 2001

Submission Instructions for Workshop Proceedings

Post-Meeting Discussion Forum

Discovery space in astronomy is strongly limited not only by flux and resolution, but also by sample size. In particular, many fields in astronomy would greatly benefit from the ability to spectroscopically study large samples efficiently. For example, large scale spectroscopic surveys have recently begun placing unique constraints on cosmology, large scale structure, galaxy evolution and Galactic structure. If the capability for highly multiplexed spectroscopy were available, we would be able to not only answer existing questions more robustly (perhaps unambiguously), but also open up new avenues of investigation. Moreover, these programs could be accelerated from timescales of decades or years to months.

Given the interest expressed in a highly multiplexed spectroscopic capability at the recent Scottsdale system workshop and the possibility of university-scale investments in this area, we are holding a community wide workshop to investigate the scientific need for such a capability and its technical challenges. The goals of the workshop will be to determine what scale of facility is demanded by the science (i.e., what field of view, what multiplexing capability, and on what aperture), and to identify a path by which to realize such a capability.

The workshop attendance is limited by the size of the available conference room. The participant list is almost full, but a few spaces remain. If you are interested in participating in the workshop, please write to Arjun Dey ( as soon as possible.

Transportation Information:


The workshop structure is aimed at engendering a lively discussion on the major science drivers and the technical feasibility, and hence a significant fraction of the time in each session will be devoted to discussion. The first day of the workshop will focus on the science drivers and the second will focus on the technology and techniques for highly multiplexed MOS spectroscopy, as well as a discussion of the lessons learned from ongoing instrument and spectroscopic survey projects.

In each session on the science drivers (Day 1) there will be one or more invited talks which should briefly review the status of the field and then focus on which aspects of the science would be revolutionized by highly-multiplexed multiobject spectroscopy. Following the invited talk, there will be a structured discussion during which workshop participants are invited to present a short (1 or 2 viewgraph) comment pertinent to the discussion on the scientific drivers. Each session on technology (Day 2) will be structured with invited talks and discussion focussed on how to best serve the science drivers emerging from the science sessions.

In the spirit of having a lively discussion, we encourage workshop participants to come prepared with one or two viewgraphs to contribute to the discussion. If you wish to present something of relevance to the discussion in one of the sessions, please contact Arjun Dey ( with a brief (2-3 line) summary of what you would like to present.
