GSMT NSF Science Working Group Rolf-Peter Kudritzki NOAO Town Meeting 07 January, 2003
Goals of the SWG SWG is a community-based group convened to: • Formulate an inspiring and powerful science case for federal investment in GSMT • Identify key science drivers • Develop clear and compelling arguments for GSMT in the era of JWST/ALMA • Discuss realization of key science as a function of design parameters: aperture, FOV, PSF…… • Generate unified, coherent community support • Represent the community in facilitating public-private-international partnerships
SWG Membership Rolf Kudritzki, IfA (Chair) Paul Ho, CfA Jill Bechtold, UA Claire Max, LLNL Michael Bolte, UCSC Chris McKee, UCB Ray Carlberg, U Toronto Jonathan Lunine, LPL Matthew Colless, ANU Francois Rigaut, Gemini Alan Dressler, OCIW Doug Simons, Gemini Irene Cruz-Gonzales, UNAM Steve Strom, NOAO Betsy Gillespie, UA Terry Herter, Cornell
SWG Activities to Date • Kick-off meeting, Tucson, July 29-30, 2002 • Charge to SWG by NSF • Strategic approach and formulation of goals • Expansion of membership • Discussion and selection of key science areas • Formation of task groups to develop science cases
SWG Activities to Date • Telecon, September 11, 2002 • First review of existing science cases • GSMT book; CELT book; others • Assignments to flesh out science cases for: • Extra-solar planets • Solar system science • Star formation and interstellar medium • Stellar seismology • Stellar populations in the local universe • Evolution of glaxies • AGNs and black holes • Cosmology and large-scale structure • Define needs for • Extreme and multi-conjugate AO • AO simulations • Field of view and supporting simulations
SWG Activities to Date • Meeting at UH IfA on Dec 4-5, 2002 • Involved SWG and representatives from NSF • Review of science cases • Definition of key science areas for further, detailed study • Initial discussion of AO simulations • Presentation of UH High Dynamic Range Telescope concept & related science
Planned Meetings • Early March (Los Angeles) • Late April (Honolulu) • Goals: • Finalize science cases • Refine AO simulations • Crowded field MCAO photometry • Extreme AO • Astrometric performance of GSMT AO • Ground-layer-compensated AO and delivered field of view • Performance estimates of MCAO vs. aperture • Presentations by other ELT groups (CELT; TMT) • Key science • Relationship between design concept and delivered ‘science value’ • Discuss key science as a function of design parameters: • Aperture; FOV; PSF vs FOV; emissivity; wavelength range
Key Science Cases Under Study • Exploring other planetary systems • Direct detection • Physical characterization • Habitable zones; life on planets • Solar system analogues • The birth of stars and planets • Formation of stars and protoplanetary disks • Evolution of disks • Kuiper Belts around the sun and other stars • Protostellar clouds • Birth and evolution of massive black holes • Galactic center black hole • Nearby massive black holes • Black hole demographics; growth of black holes
Key Science Cases Under Study • Birth of galaxies • Characterizing galactic building blocks • Kinematics; star-formation rates; chemical composition • Studies of assembling galaxies • Studies of component stellar populations in nearby galaxies • Understand merger history • Cosmology and large-scale structure • 3-dimensional baryon map at high redshift from absorption line studies
Next Steps • Develop and vet key science cases • GSMT SWG + interaction with/contributions from the community • Provide input to NSF prior to June, 2003 • Compelling presentation of key science cases • Understable by & exciting to a broad audience of scientists and policy makers • Define complementarity to ALMA; JWST; other major facilities as well as the unique role of GSMT • Define technology challenges (e.g. AO) • Work with NSF to enable substantial funding of GSMT engineering studies (possibly in private/public partnerships)
A very personal view • GSMT provides • outstanding science opportunities for the next generation of astronomers • a tool for addressing key questions of modern science However…….. • GSMT brings projects of ground-based astronomy into a financial domain comparable to accelerators in particle physics
A very personal view • In order to obtain federal funding of such substantial amounts, the community must be • well organized • demonstrate clear consensus • This does not appear a strength of the US O/IR community, at least at present • SWG hopes to contribute to the process of consensus building as a first step toward evoking federal support for GSMT
