NGSC Operations Support • Phoenix high-resolution IR spectrograph: service observing on Gemini South – 50 science nights scheduled in 2003 A – Hinkle, Blum, van der Bliek, & Ridgway support • NGSC Staff involvement in Commissioning & System Verification for new Gemini instruments – GMOS South: M. Bergmann, C. Smith – T-Re. CS: 2 System Verification programs of NGSC Staff – Many NGSC Staff proposing for ALTAIR + NIRI SV, MICHELLE imaging SV, GMOS-South IFU SV • Develop arrangement to help support Hokupa’a-85 + Abu Adaptive Optics Imager on Gemini South • Develop a remote operations capability in Tucson (GROC) & La Serena using high-speed video and computer links to Cerro Pachón and Mauna Kea
Community Outreach • Host special-topic science & analysis workshops – Future NGSC workshop ideas: • • mid-IR observing opportunities at Gemini Integral Field Unit (IFU) opportunities at Gemini Using IRAF to reduce your Gemini data GNIRS observing & calibration • NGSC at AAS meetings: booth at Seattle AAS (posters, brochures & Observing Tool demonstr. ) – do same at Atlanta AAS (January 2004) • • • NGSC presentations at U. S. institutions NGSC Webcast on Gemini 2004 A Proposals Postdoc program (2 general; 3 South American) Gemini Science Meeting in 2004 (NGSC Support) U. S. Gemini SAC is NGSC’s community-based advisory council
NGSC Instrumentation Activities • Mission – instrument procurement in U. S. for Gemini telescopes – analogous function in other partner countries • Activities – NGSC let all the current U. S. instrument contracts – provide advice & liaison to the instrument teams – carry out management oversight • Co. DR, PDR, CDR, acceptance testing • Quarterly Reviews • release of payments only when specified milestone met – report progress to International Gemini; coordinate communications between the instrument team & Gemini
U. S. Instrument Developments • T-Re. CS: mid-infrared imager and spectrograph for Gemini South (Florida) – Delivered to Gemini South 12 April 2003 – Followed by integration, acceptance testing, & commissioning – First light took place 2 June 2003 – TAC-approved science programs beginning execution! • GNIRS: workhorse infrared long-slit / IFU spectrograph for Gemini South (NOAO) – Pre-shipment acceptance test completed 15 October 2003 – GNIRS shipment to Gemini South imminent – Mounting GNIRS on Gemini South planned for December 2003 – GNIRS first light planned for January 2004
U. S. Instrument Developments • NICI: dual-beam coronagraphic infrared imager for Gemini South (MKIR) – NASA funded – Procurement / fabrication phase ending; integration phase beginning – December 2004 delivery planned • Flamingos-2: multi-object IR spectrograph and imager (Florida) – Management Review in late January 2003 – NGSC assisting Florida personnel in project management techniques (Gaughan & Eklund) – Flamingos-2 contract approved and signed in early May – Critical Design Review took place in August – December 2005 delivery planned
US Next-Gen Gemini Sci/Inst Planning • Workshop: May 29 -31; Tempe, Arizona • Goal: Key Gemini Science Programs for 2008 -2010 Realm – High-impact science questions / projects – What observations are needed to answer the science question? • 40 participants; diverse in science interests & institutional affiliation (includes most of the U. S. Aspen delegates) • E-mail & telecon preparatory discussions • Four Science Breakout Groups – Stars, the Solar System, and Extra-Solar Planets (leader: J. Valenti) – Star Formation Processes and the ISM (leader: M. Meyer) – Structure and Evolution of the Milky Way and Nearby Galaxies (leader: R. Wyse) – Formation and Evolution of Distant Galaxies and the High-Redshift Universe (leader: K. Glazebrook) • Written report on Tempe conclusions on Web • Two briefings/discussions on Tempe results for U. S. Aspen delegates; firm up U. S. consensus
Tempe Over-Arching Questions • Formation and Evolution of Planetary Systems • Formation of Stars & Brown Dwarfs over the Mass Spectrum • Origin of the Elements • Origin of the Hubble Sequence • Dark Matter and the Formation of Galaxies from Substructure • Dark Energy and Cosmic Sound • Reionization History of Universe • Feedback from Stars & AGN on Galactic Evolution
Aspen International Gemini Next. Generation Instrumentation Meeting • • June 27 -28, 2003; Aspen, CO Half of delegates from U. S. Half of science group chairs from U. S. Written report on science questions and instrumental requirements • National Gemini Offices (NGSC) then estimated ROM costs for each instrument concept • “Aspen” report submitted to Gemini Science Committee for its October 13 -14 meeting • To be considered by Gemini Board at its November meeting
“Aspen” Instrument Summary
Open NGSC/Gemini Issues • Are the science needs of U. S. community at large aperture being met by Gemini? Any issues impeding user science? • Do the “Aspen” instruments represent a bright scientific future for Gemini? • What are the near-term priorities for commissioning Gemini instruments? • What data reduction software is most needed for U. S. Gemini users? • Is there demand for both Queue and Classical observing with Gemini by our community? • The U. S. Gemini SAC has discussed all these questions.
