  1. The European ELTScience Case DevelopmentIsobel Hook

  2. Outline • Some history • Role of OPTICON in the E-ELT • Highlights from FP6 • Science Working Group • Community meetings • Science case development and the DRM • Plans for FP7

  3. Context • Before OPTICON ELT in FP6 • OWL 100m concept : internal ESO project • Euro-50 concept • Science community starting to get involved • OPTICON in FP5 provided the starting point, expanded in FP6 • Substantial technical design work required • initiated ELT Design Study in FP6

  4. The early days: pre 2000 • OPTICON was started as a deliberate move to improve European coordination in optical-IR astronomy • At the time, 2 major astro countries were not in ESO (UK, Spain), and their future allegiance was unclear • There was very little contact between the many european national facilities/agencies • Non-national astronomers were allowed national telescope access on merit, but were not encouraged, and were unfunded to use it: poor precedent • There were competing future projects (OWL, Euro-50, CFHT-futures), and dreams, no one of which had adequate community or financial support. And many organisational options (ESO, ENO, multi-laterals, eg Gemini, LBT). Europe was at risk of being left behind. • The EC was starting to get involved in basic science, with unclear future implications for funding and projects. Being involved in EC funding was sensible insurance

  5. The new millenium • The first Opticon (FP5) Board [04/2000] resolved:OPTICON strongly supports and encourages developments of future large scale astronomical facilities, in particular an extremely large optical/ir ground-based telescope. Opticon establishes a ``Science Case for the Extremely Large Telescope’’ WG, with a goal of developing a draft case by May 2001. The activity will be under the general overview of Roberto Gilmozzi, with the Chairman (GG) and Alvio Renzini (ESO) providing Europe-based joint support for the activities. • then negotiated agreement between ENO/IAC, ENO board ( Setti), ESO (incl OWL) and Euro-50 for a single European effort. ESO and Opticon had a CfP for leaders of a single ``design independent’’ EC-funded design study. CC and GG appointed the team. • The goal was to get all Europe on one team.

  6. Building one community all on the same team… Competing European large telescope projects…

  10. Jun 2005: OPTICON FP6 Science case for a 50-100m telescope Nov 2005: OWL concept review Dec 2005: New E-ELT WGs formed (community + ESO) Science, AO, Telescope design, Instrumentation and Site reassessed May 2006: SWG formally merged with OPTICON ELT activity Sep 2006: Design Reference Mission began (SWG+ESO) Nov 2006: E-ELT Marseilles Conference Baseline 42m E-ELT concept presented to community Dec 2006: E-ELT Phase B approval by ESO council EU FP6 ELT DS (technical work) aligned – continues until end 2008 Jan 2008: E-ELT “Prep Phase” Program started (EU FP7) Aiming to produce a proposal for construction in June 2010 History of the E-ELT

  11. FP6 OPTICON N3.1: ELT Science Case • Aim: To develop and promote the ELT science case • Planned deliverables: • Web site within first 6 months • 1 community Science WG meeting per year • 1 smaller meeting (group Chairs) per year • Major science case documents at mid & end point • Employ a scientist to coordinate this activity • Coordinate with FP6 ELT design study work • Work has been successful and going to plan – in a rapidly developing environment!

  12. Current role of OPTICON in the E-ELT • OPTICON is recognised as the crucial link between the community and the new ESO European ELT project • ESO-OPTICON SWG formed in May 2006 • 21 members, 50:50 Community:ESO • co-Chairs Isobel Hook & Marijn Franx • Provides scientific input to ESO ELT project • Provides coordination of effort in the community • OPTICON has major role in organising community meetings

  13. Science Case Development • OPTICON Science case documents produced in 2005 • ESO SWG science report in April 2006 • After merging the SWGs, the OPTICON-ESO SWG produced the science cases as input to the Design Reference Mission • Now a dedicated WP in FP7 “ELT Prep Phase” program to produce simulated data for these cases • SWG provides the scientific input and analysis of the results

  14. DRM output • Matching of DRM science cases to instrument capabilities has guided the calls for instrumentation studies • Now using the DRM to assess the impact of site parameters on science

  15. Site parameters Draft assessment of sensitivity of science cases to site parameters Currently being reviewed by SWG DRM proposals

  16. Background on FP7 “E-ELT Prep-Phase” WP on the DRM Parallel activity to produce simulated data Relies on scientific input from the SWG 16

  17. 10-8 10-7 10-5 10-9 10-10 10-9 Exo-planet imaging in J-band Preliminary (EPICS team) DRM: status of simulated data • 3 Demo cases • Exo-planets - advanced • Stellar pops imaging - advanced • Physics of galaxies - completed 1 arcsec Crowded stellar field in Virgo I and K-band; LTAO (J. Liske) z~4 rotating disk galaxy Simulation (M. Puech): 10-hr integration, MOAO 17

  18. CODEX simulation (J. Liske) DRM status II • Stellar disks - started • IMF imaging - started • Stellar pops spectroscopy – started • Black holes – started • High-z galaxy imaging - started • CODEX case – advanced 5x106 Msun Black Hole at Virgo (Emsellem) JWST ELT + MCAO 0.9” z=4 galaxy- Preliminary (M. Puech) Stellar disk in near + mid IR (Pinte & McCaughrean) 18

  19. Other OPTICON E-ELT Activity

  20. Specsim software • Developed by Nuria Lorente, originally for JWST-MIRI • OPTICON-funded staff effort (few months) used to adapt the code for E-ELT instruments, especially IFUs • Input • Source positions • instrumental PSF • Instrument, telescope and sky transmission functions • Output • Simulated data-cubes that can be analysed in same way as real data • Software has been used to simulate EAGLE (multi-IFU) science data. Adaptable to other ELT instruments.

  22. Web Sites • “Original” OPTICON ELT SWG web site at Oxford • Now hosted at ESO as part of central E-ELT web pages. Includes - • DRM science cases • Reports & presentations community meetings

  23. Future Plans

  24. Revised OPTICON FP7 plan (reduced budget) • Deliverables/ Tasks • Updated science case to be delivered to ESO as input for construction proposal • Employ staff to develop ELT science case in the community • SWG travel support • 2 community science meetings • Effort • I. Hook (lead, part time. Note joint position between U. Oxford and INAF from 1/1/09) • 1 FTE postdoc-level scientist (could be more than one person) location(s) TBD • Budget • Staff : ~ 245 kEuro • SWG and community meetings = 55 kEuro • Total For 3 years = 300 kEuro

  25. Next 12 months • OPTICON • Sponsor community ELT meetings : Next in Nov 2009 (FP7) • Final FP6 science case report (end 08) • Continued close coordination with technical work • OPTICON – ESO SWG • Science case and scientific input to DRM • Provide scientific input to E-ELT (on behalf of community) • (FP6 ELT Design Study) • Technical work continues until December 08 • (E-ELT” Preparatory Phase” in FP7) • DRM science-to-simulation translation work continues until end 2009

  26. Conclusions • OPTICON provides the link between the E-ELT project and the science community • Community meetings • Science case documents • Scientific input to the E-ELT project • www.eso.org/projects/e-elt

  33. ELT and the Astronet Science Vision A.Do we understand the extremes of the Universe? • Measure the evolution of the dark-energy density • Test for a consistent picture of dark matter and dark energy • Understand the astrophysics of compact objects and their progenitors B. How do galaxies form and evolve? • Map the growth of matter density fluctuations in the early Universe • Detect the first stars, black holes, and galaxies • Determine the evolution of the galaxy cluster mass function • Make an inventory of the metal content of the Universe over cosmic time • Measure the build up of gas, dust, stars, metals, magnetic fields, masses of galaxies C. What is the origin and evolution of stars and planets? • Determine the initial physical conditions of star formation • Unveil the mysteries of stellar structure and evolution, also probing stellar interiors; • Understand the life cycle of matter from the interstellar medium • Determine the process of planet formation • Explore the diversity of exo-planets in a wide mass range from giants to Earth-like • Determine the frequency of Earth-like planets in habitable zones and push towards direct imaging D. How do we fit in? • Constrain the models of internal structure of planets and satellites • Studies of Titan, Mars, Europa and other outer satellites.
