1 ASTRONET Science Vision and Road-mapping (observer’s view)
ASTRONET – funded by EC to develop strategic plan for European Astronomy 3yr programme; now half-way through Gathered science input & written broad science ‘vision’ Symposium: Poitiers, Jan 2007 Talks (Lobanov,Diamond,Falcke, Beck,…); Lobbying,… Roadmap of facilities required to achieve vision due Sep 2009 Draft Vision docs Symposium presentations Roadmapping panels

2 Comments on Process Serious exercise Noble aims Motives
Led by Tim de Zeeuw; panel chairs include Peacock, Bergeron, Kennicutt, Testi >220 at Poitiers meeting Noble aims Long term vision (10-20yr) ; start with key science questions in 4 areas; identify generic requirements & facilities Roadmapping team (led by Mike Bode) to develop prioritized plan of facilities required Motives Prominence of ELT; pressure on existing facilities

3 Relationship to EVN2015 Aware of process; align science?
Lessons from process Involved in road-mapping Panels being formed; expect radio membership Concern over low profile of VLBI, MERLIN,… Partly taken for granted General issue for road-mapping Successful raising of radio, SKA profile at Poitiers meeting Focus on road-mapping Importance of angular resolution (parameter space) Importance of cm-wavelengths Global VLBI in SKA era

4 A: Extremes of the Universe (Peacock)
Topic Issues Experiment Facilities How did universe begin inflation Measure ns, r CMB pol Nature of DM, DE DE eqn of state Baryon osc. Cosmic shear SN surveys OIR survey, SKA Observe strong gravity Orbits, BH horizon GW BH mapping PTA PSR timing GWO mm-VLBI SKA How do SNe, GRB work Core collapse Mergers Progenitors, light curves, sim. ELT, X, VLBI-SKA BH, accretion,outflow Disks-jets Environmental impact Multi- high res imaging; time domain Particles

5 B: Formation and Evolution of Galaxies (Bergeron)
Topic Issues Experiment Facilities Emergence from dark ages First stars Ionisation sources Zcrit AGN surveys 21cm fluct ELT SKA, X SKA Cosmic web Cluster DM ICM evolution High-z clusters Cosmic shear Xray surveys SZ WFOIR X Where are metals Inventory z~3 Local univ. HI, Lya,metal abs census Gal winds WHIM ELT, UV, Assembly of galaxies Cold gas SFR AGN/SB role Hubble seq Role of B SFR vs N(HI) Multi- Madau IR spec Survey RM survey SKA, ELT ALMA, ELT,.. 10-20m IR Formation of MW 1st stars DM tidal streams Stellar kinematics GAIA

6 C: Origin, Evolution of stars & planets (Testi)
Topic Issues Experiment Facilities How do stars form Role of B, turbulence, Cluster environment High res imaging of local + extragal starforming clust. SKA, ALMA, JWST What controls IMF Universal? Origin Extragal Galactic ELT GAIA ALMA Stellar interiors Convection & rotation asteroseismology CoRoT,… Life cycle of ISM Simple  pre-biotic Feedback to ISM Chart composition through life cycle ALMA, SKA, Herschel Formation of planetary systems Dust & gas  pebbles Interaction with star, environment Disks, gaps Evolution to pebbles ALMA, SKA, JWST, ELT Demographics of planets How many Earths Planet hunters Doppler, ELT, GAIA,… Signs of life Biomarkers SETI ELT, SKA

7 Discussion & Recommendations
Strong recommendations in draft doc (though connection to case less clear!) Some clarification in discussion sessions Killer Tools (new facilities) SKA, GWO, CMB Pol, OIR Survey, ELT, Large X-ray tel mm-VLBI, UV Space tel (4-8m), 10-20m IR tel, space photometry, high precision RV, pos Identify medium term goals for mm/cm-wavelength VLBI

11 Conclusion Key questions  current issues  observables & experiments
Unlikely that we miss anything… … might consider using parallel themes ‘SKA’ prominent in requirements Look where high-sensitivity (<uJy), high resolution (mas), moderate FOV (arcmin) cm-wavelength is required EVN2015 can have significant impact in majority of topics Will be represented in road-mapping exercise this will properly incorporate existing facilities
