Atacama Large Millimeter Array 64x12m Antennas Frequency range 30-1000 GHz (0.3-10mm) 14km max baseline (<10mas) ALMA Compact Array (short spacing and total power) Detecting CO and [C II] in a Milky Way galaxy at z=3 in less than 24 hours of observation To map dust emission and gas kinematics in protoplanetary disks The ability to provide high-quality and high resolution imaging in the millimeter and submillimeter bands to match that of HST and ground-based AO-equipped telescopes
Alma sensitivity Observing thermal sources, there is no point having angular resolution without sensitivity to low brightness temperature Alma allows 30 K rms with 30 mas res. at 1mm
Red shifted CII and OI lines CO at z=6.4 is already seen With ALMA one will see the fine structure lines of CII(157 micron) and O I(63 micron) (for z> 2 (CII) and z>5(OI)), so one can measure the cooling directly.

Project schedule towards ES Will be revised soon Early Science
Science Operations Plan
ALMA SW: Expectation for Early Science Observation Preparation All modes offered to the users will be supported from the Novice to the Expert levels. At the very beginning of Early Science, the Novice mode behaviour will be mostly based on expectation from simulation and initial testing rather than on a solid experience with ALMA Science Pipeline Not available to the users for Early Science (it will be in the heuristics “learnig phase”) Offline Data Reduction Package (AIPS++) All modes offered will have been fully tested and supported No Graphical User Interface will be available for Early science A solid well tested User Interface and scripting language based on Python will be available

Risposte alla Call di ESO per ARC Nodes Germania (UniBonn, MPIfR, UniKoeln, UniBochum) IRAM (Francia, Germania-MPG, Spagna) Italia (INAF-Istituto di Radioastronomia) Paesi Bassi (Leiden, + probabilmente Belgio) NORDIC-Onsala (Svezia, Danimarca, Finlandia, +…) UK (Jodrell, Edinburgh, Cambridge, +…) (Portogallo & Svizzera) Ogni nodo fornisce servizi di base e servizi specializzati (per tutta la comunità Europea)
Where is italian mm astronomy Disadvantaged rel. to IRAM countries but with interest in certain areas Quite a few “theoretical groups” (esp. Cosmology) Stellar (circumstellar) groups absent
