ASTRONET Science Visionand 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

www.astronet-eu.org– Draft Vision docs– Symposium presentations– Roadmapping panels

Comments on Process

• Serious exercise– 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

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

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
