AGENDA - LAST UPDATE: 02/10/2008

WEDNESDAY, OCTOBER 8th
 
9:00 -- 9:30 Welcome, meeting guidelines and latest "site testing" results

V. Minier (CEA Saclay)

SCIENCE: BIG QUESTIONS TO BE SOLVED BY SUBMM ASTRO  (chair: V. Minier)

09:30 -- 09:45 Galactic Star Formation and ISM spectral lines

L. Olmi (IRA-INAF Firenze) & on behalf of C. Kramer (IRAM)
 
10:00 -- 10:15 Magellanic clouds

F. Israel (Leiden)
 
10:15 -- 10:45 Galaxy evolution and submm spectroscopy of galaxies

E. Daddi (CEA Saclay) & L. Spinoglio (IFSI-INAF)

Coffee break
 
11:15 -- 12:30 SCIENCE Discussion (chair: L. Olmi)

(the goal is to define the most relevant issues for a single-dish instrument)
 
Some specific questions to be answered:
- Is a 12m Dome-C single-dish submm telescope competitive for astrophysics ?
- Will it be able to carry out optimum post-Herschel science ?
- Will it be useful for Herschel follow-up and ALMA parallel studies ?
- FIR/submm background: can it be resolved by a 12m antenna at Dome C ?
- Magellanic Clouds: can it be a strong science driver?
- For what science goals is the 200 micron waveband fundamental ?
- Submm wavelengths are well suited for S-Z effect ?
- For what science goals is MIR from Dome-C fundamental?
- Does Dome-C open unique windows for spectral line works?
- Should we consider the ESO-ALMA prototype antennas or a BIGGER instrument?

LUNCH (12:30 – 13:30)
 

SITE TESTING (chair: N. Tothill)

13:30 - 13:45 Atmospheric transmission at Dome C  and comparison to other sites

P. Tremblin (CEA Saclay)

13:45 – 14:00 Environmental constraints

G. Durand (CEA Saclay)

14:00 – 15:00 Discussion on logistics requirements including the following issues:

- the vertical temperature gradient in the boundary layer

- the high relative humidity in the boundary layer

- the wind-speed gradient in the boundary layer

- the temperature fluctuations in the boundary layer

- the low atmospheric pressure (which makes things difficult to cool, not difficult to heat!)

Coffee break

INTERFEROMETERS (chair: L. Spinoglio)

15:30 – 16:00 FIR interferometry context
F. Helmich (co-PI of FIRI)
-    Science with bolometer interferometry
-    Science with THz heterodyne interferometry
-    Ground vs. Space
-    Pathfinder for FIRI (space observatory).

16:00 – 17:00 Discussion on interferometry
Round table on the involvement of represented institutes in FIR interferometry
-    Science
-    Bolometer
-    Beam combiner
-    Heterodyne receiver
-    FIRI
Facilities and atmospheric requirements
- How many (and what diameter) antennas?
- What difficulties building a FIR interferometer at Dome-C?
- How much would a 12m antenna help?

17:00 -- 18:00 Final Discussion:
Potential of Dome C for submm astronomy: yes or no ? Conclusions of the WG.
If yes, how to establish a road-map for a large submm-wave facility in Antarctica
