SIM KP Group Members

Steve Majewski (Principal Investigator), UVA Website, Email	John Bahcall, IAS Website, Email Bahcall will lead the Oort limit project analysis. He will develop a program to simulate the SIM observations of disk stars, and work with Majewski's group on developing and characterizing the proposed Oort limit target samples.
Doug Geisler, U. Concepción Website, Email Geisler will be part of the program of identifying halo K giants using photometry. He is a co-I in the Grid Giant Star Survey (GGSS), and the PI of a SIM preparatory grant to do follow-up photometry and spectroscopy of Grid stars.	Wolfgang Gieren, U. Concepción Website, Email Gieren will play an important role in establishing and characterizing the Cepheid target list, assisting with spectroscopy of bulge stars, and the creation of the GGSS and halo K giant samples.
Eva Grebel, Max Planck Institut für Astronomie Website, Email Grebel is playing an active role in the search for tidal tails around dwarf satellites and globular clusters. She provides privileged access to MPIA's telescope facilities, and has been leading the search of the open cluster literature to identify brightest member stars.	Carl Grillmair, Caltech/SIRTF Science Center Website, Email Grillmair is is leading our associated program to obtain Hubble Space Telescope astrometry to complement SIM measurements of the Galactic bulge and bar populations. He will play a key role in the pre-launch search for tidal streams associated with dwarf galaxies and globular clusters.
Michael Irwin, Cambridge University Website, Email Irwin will be part of the effort for identifying candidate stars in tidal tails and detecting tidal streams in globular clusters and dwarf galaxies. He has played a major role in the discovery and identification of halo globular clusters and satellite galaxies, including Sagittarius.	Kathryn Johnston, Wesleyan University Website, Email Johnston will be responsible for theoretical aspects of the disk and tidal tail studies. She will participate in extending the disk study to look at the effect of resonances on the analysis, modeling support for selection of tidal tail candidates, and examining the evolution of tidal tails in galaxy formation simulations.
Ricky Patterson, University of Virginia Website, Email Patterson will play a key role in organizing the day-to-day operations of many observational programs. He will be involved in the K giant samples for the halo and Oort surveys, the project to determine proper motion of globular clusters and dwarf galaxies, and the search for tidal tails.	I. Neill Reid, STScI Website, Email Reid will lead the observational program to identify Cepheid and Mira variables suitable for probing the potential of the Galactic disk. He will also collaborate in the Oort limit determination.
David Spergel, Princeton Website, Email Spergel will be leading the analysis of R0 and the study of the bulge kinematics. He will construct a model for the Galactic bar and explore implications for the formation of the bar. He will also be part of the disk and tidal tail analysis efforts.	Scott Tremaine, Princeton Website, Email Tremaine will lead the analysis of the hot halo tracers. He will also investigate phase-mixing in galaxies formed by mergers to determine the influence of incomplete mixing on halo tracers, and continue work on simulations of SIM observations of disk parameters and on the Oort limit analysis.
