4 Context Context Large projects proposed for the next 10-20 years in astronomy and astro-particle physics constitute several thousand million € Large projects proposed for the next 10-20 years in astronomy and astro-particle physics constitute several thousand million € EU only provides for a few % of this cost; the funding agencies the rest ASTRONET thus established to help national funding agencies to take science-based, rational, coordinated decisions for the long term benefit of European astronomy - and, at a higher level, to help unlock further necessary resource for our science ASTRONET thus established to help national funding agencies to take science-based, rational, coordinated decisions for the long term benefit of European astronomy - and, at a higher level, to help unlock further necessary resource for our science (~ Producing a (better) counterpart of the US Decadal Surveys) (~ Producing a (better) counterpart of the US Decadal Surveys) 22/03/2012RIA meeting4

25 Some considerations Serious lack of resources Existing Agreements for most observatories Top priority for instrumentation 4m telescopes becoming highly specialized HR spectroscopy for TNG 3.5m CARMENES for CAHA 3.5m WEAVE for WHT 4.2m No obvious mechanism to compare facilities 22/03/2012RIA meeting25

26 Are the 2m telescopes different? 2m telescopes are not so much specialized To consider 2m (CAHA 2.2m + NOT 2.5m + INT) as starting point? Small number of nights (5-10 / semester) Mechanisms to guarantee minimum fair return to telescope owners Implement as option of Opticon CTAC (only available for the specific telescope communities) 22/03/2012RIA meeting26
