ALMA

• International project to build & operate a large (66 antennas) millimeter/submm ( ~0.4-3mm) array at high altitude site (5000m) in northern Chile.

• Project began in 2002; Japan joined in 2004; early science from 2011; inauguration and 66th antena delivery in 2013

• Two orders-of-magnitude improvement in mm radio astronomy capabilities.

Cycle 1 (2013 Jan-2014 May) Status

• Originally planned to end in 2013 Oct, but rescheduled to end in 2014 May, mainly due to a re-prioritization of the commissioning activities

• In addition, we suffered from adverse weather conditions, power issues, a worker’s strike.

• We are resuming to normal operation in November…

• Only half of Cycle 1 Highest Priority project will be completed by the end of Cycle 1.

• We offer “Cycle 1 Transfer” eligible to Cycle 2 if projects are not completed within Cycle 1, if PI agree to make the proposal metadata (abstracts, positions, frequency, angular resolution, sensitivity) public

Status of Cycle 1 projects

Cycle2 TimelineCycle2 Timeline

•Call for proposals :Oct 24, 2013•Deadline :Dec 5, 2013•Start of observations :Jun 1, 2014•End of observations :Oct 31, 2015

•From Cycle 2, South Korea will become ALMA partner country

Cycle 1 completion expectation

Cycle 1 Transfer

• Only half of Cycle 1 HP will be completed by the end of Cycle 1

• We offer “Cycle 1 Transfer”• If PI wish it and agree to make proposal metadata

(abstracts, target positions, frequencysetups, angular resolution, sensitivity) public, the program will be eligible for Cycle 2 if not completed in Cycle 1

• Deadline for “Cycle 1 Transfer” is October 31.

• Note that you should check duplication of your Cycle 2 proposal(s) with Cycle 1 Transfer public metadata

Refereed papers from ALMAPI data vs public data

Google “EA-ARC Guidebook”

• Prepared by James Chibueze (EA ARC)

• How to get FITS and raw• How to get CASA

ALMA archive astronomy

• Typical Cycle 0 data size ~200 GB• Cycle 1 data size can be close to ~1 TB

• Official ALMA archive provides you with full archive (explanation, raw data, successful CASA script, FITS image, etc) – it is BIG

• First we recommend seeing FITS image on JVO, before full download

• We recommend using CASA version used in delivered data reduction — CASA is very sensitive to versions

The Atacama Large Millimeter/submillimeter Array (ALMA), an international astronomy facility, is a partnership among Europe, Japan and North America, in cooperation with the Republic of Chile. ALMA is funded in Europe by the European Organization for Astronomical Research in the Southern Hemisphere, in Japan by the National Institutes of Natural Sciences (NINS) in cooperation with the Academia Sinica in Taiwan and in North America by the U.S. National Science Foundation (NSF) in cooperation with the National Research Council of Canada (NRC). ALMA construction and operations are led on behalf of Europe by ESO, on behalf of Japan by the National Astronomical Observatory of Japan (NAOJ) and on behalf of North America by the National Radio Astronomy Observatory (NRAO), which is managed by Associated Universities, Inc. (AUI).
