Australia’s role in the age of ALMA?
•Mopra + ATCA
•ALMA (staged opening to 2012)
•Complementarity
•Community vitality to SKA
What will ALMA be missing?
• Only cover 3-4 of the 10 wavebands– 3mm + 1mm + 0.8mm + 0.4mm– No 7mm, 12mm, 2mm– Limited use at 3mm?
• Small Field of View– ~arcminute
Mopra3mm + Wide Bandpass
• Finder Telescope– c.f. Schmidt vs. AAT
• Teaching Facility– Model for CSIRO / University
Collaboration– Wider access to funding sources
• 2mm - reshape dish?• 3mm - multibeam• 7mm - receiver, then multibeam
The ‘DQS’
ATCA MM-interferometer
• Fed by Mopra, Feeds ALMA– Provide a foundation for ALMA
science
• 12mm • 3mm multibeam
– c.f. ALMA’s small FOV
• 7mm– untouched by ALMA
• 2mm?• Real time phase monitoring
How to fund and support this?
• CSIRO – University Collaboration– $1m into mm-astronomy since 1998
• ARC Linkage Infrastructure (LIEF)• University capital grants
• International partners– Collaborate to, e.g., obtain multi-beam?– New sources; e.g. Singapore?
• Teaching + Research– Don’t forget the value of combining the two!
What to do about ALMA?• Australia must find a way to play some role in ALMA to ensure the
continued vitality of its astronomical community in the pre-SKA era.• ESO??
– Solves both the ELT + ALMA issues!
• Strategic International Alliances– Chile
• Our southern hemisphere cousin• Builds on established and productive links
– ARC Linkage for exchanges and access?
• Position ourselves to take advantage of any opportunities that may arise in Antarctica– e.g. HEAT at Dome A
MopraA model for University–CSIRO collaboration
• Teaching and Training– 5 mm workshops– Nurtured a mm-community
• Brings new resources– Attracted ~$1 million in funding to
astronomy– 22m dish, wide-band correlator,
OTF mapping, Friend of the Telescope etc.
• Fostered Intl collaboration– SEST, ESO– Chile
Working with UniversitiesIt took 5 years to build to OTF mapping
• Needs nurturing:– Slow at the start, but sure in the end.
• Teaching and Research– Develops a community– Opens new funding opportunities– Fosters new science opportunities
