  1. European ELT Science Case Isobel Hook

  2. 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

  3. 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!

  4. Who we are: OPTICON ELT SWG • SWG formed in 2003 • Coordinator: Isobel Hook (50% funded by OPTICON) • 6 Group chairs • Stars & Planets - Hans Zinnecker & Rafael Rebolo • Stars & Galaxies - Mike Merrifield & Sergio Ortolani • Galaxies and Cosmology - Jacqueline Bergeron &Bruno Leibundgut • + many volunteers from around Europe

  5. ELT Science meetings Marseilles 2003 Florence 2004 Marseilles 2006

  6. Highlights from FP6 so far • Meetings to date: • 3 major + 4 smaller meetings organised by OPTICON • Marseilles 03, Florence 04, Marseilles conference 06 • Funding for Europeans to attend several other meetings (e.g. IAU ELT Symposium, Cape Town) • Science case documents • Top level summary Feb 2005 • Science case book Jun 2005 • Mailing list, web site • Close coordination with Design Study • New: Joint OPTICON – ESO SWG

  7. 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 ELT DS (technical work) aligned – continues until end 2008 Recent history of the E-ELT

  8. Basic Reference Design

  9. The OPTICON role in ELT activities COMMUNITY OPTICON ESO SWG (science) ELT Design study (technical) ELT Project Offices (technical)

  10. 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 recently formed • 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 • This replaces the “smaller meetings” originally planned

  12. European ELT SWG“Prominent” Science Cases (Selected from larger list of 30 cases..) • Exo-planets • Direct detection • Radial velocity detection • Initial Mass Function in stellar clusters • Stellar disks • Resolved Stellar Populations • Colour magnitude diagrams • Abundances • Detailed abundances and kinematics • Black Holes • The physics of galaxies • Metallicity of the low-density IGM • The highest redshift galaxies • Dynamical measurement of the Universal expansion

  13. The Design Reference Mission • DRM Goals • Produce a set of science proposals and simulations • Assess science output and assist with tradeoffs • DRM Process • Scientists write proposals (OPTICON- ESO SWG) • ESO staff do technical simulations • Starting with 3“Demonstrator cases” (well underway) • Direct Detection of Exo-planets: extreme contrast extraction • Stellar populations: I-K Colour-Magnitude Diagrams • Galaxy mass assembly: multi-IFU resolved Spectroscopy • Then a wider set (based on prominent cases) • 16 observing proposals completed Need for translation!

  14. V s z ~ 4 50 mas pixels Rotating disk simulations (M. Puech) 42-m, 10-hr integration, MOAO (MCAO) Example DRM simulations z ~ 0 1 arcsec Crowded stellar field simulation (J. Liske) 10hr K-band; LTAO (MCAO)

  15. Specsim simulation tool being adapted for ELTs

  16. Next 18 months • OPTICON • Sponsor community ELT meetings (e.g. Mar 08) • Sponsor ELT talks at science conferences • “Specsim” simulation tool development • Final science case report (end 08) • Continued close coordination with technical work • OPTICON – ESO SWG • DRM development • 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) • From 1/1/08 (TBC) DRM science-to-simulation “translation” work

  17. FP7 Proposal • Deliverables • Updated Science case documents (2 over FP7 period) • Employ post-docs to develop ELT science case in the community – possibly with instrument teams • SWG travel support • 1 major community science meeting per year • Effort • 4 People working full-time on ELT science case • IMH (lead) + 3 postdoc-level scientists distributed around Europe • Coordinated with other FP7 activity • Costs per year • FTE: ~ 200kE • SWG travel support 10kE + 1 major meeting 50kE • Publication of documents: 15kE (e.g. 2 x 30kE in 4 yr period) • Total per year: ~ 275 kE . Total For 4 years = 1100 kE

  18. Conclusions • OPTICON provides the link between the E-ELT project and the science community • SWG and ESO beginning work on a DRM • www.eso.org/projects/e-elt • www.ssh-astro.physics.ox.ac.uk/~imh/ELT/SWG/ • DRM overview • SWG resolutions

  19. The End

  20. Exo-Planets Mass, orbits, frequency Direct detection (spatial resolution, Ex-AO) Radial velocity detection (to Earth Mass) Proto-planetary Disks: Formation mechanism near-IR imaging of reflected light Mid-IR imaging/spectroscopy of dust

  21. Galaxy Formation Physics of galaxy formation Relation to mass assembly, feedback Multi-IFU observations give resolved kinematics, SFR, mass 1< z < 6 Resolved stellar populations: merger history, detailed kinematics Highest redshift galaxies (+JWST) Reionisation Metal enrichment in the IGM

  22. What is the Dark Energy? Type Ia SNe spectroscopy to z~4 Direct measurement of expansion via QSO abs lines 1.5 < z < 4 “CODEX”, R~150,000, ultra-high stability Variation of fundamental parameters Physics in extreme conditions (Black holes) Fundamental Physics
