Welcome to ALMA and the European ALMA Regional Centre!

ALMA (Atacama Large Millimeter/submillimeter Array) is the world's largest ground-based facility for observations in the millimeter/submillimeter regime located on the Chajnantor plateau, 5000 meters altitude in northern Chile. It enables transformational research into the physics of the cold Universe, probes the first stars and galaxies, and directly images the formation of planets. ALMA comprises a giant array of fifty 12-m antennas, which can be configured to achieve baselines up to 16 km. It is equipped with state-of-the-art receivers that cover all the atmospheric windows up to 1 THz. In addition, a compact array of 7-m and 12-m antennas greatly enhance ALMA's ability to image extended sources.

The European ALMA Regional Centre (ARC) provides the interface between the ALMA project and the European science community. It supports its users mainly in the areas of proposal preparation, observation preparation, data reduction, and data analysis.

Getting Ready for ALMA Band 5 – Synergy with APEX/SEPIA

Published: 18 Oct 2016

ESO Workshop, Garching, Germany, 1–3 February 2017

The frequency range from 160 to 210 GHz covered by ALMA Band 5 is one of the least explored to date. This band is expected to be offered in ALMA Cycle 5, but has already been extensively used in the SEPIA instrument on APEX since 2015. Important science topics covered by Band 5 include the 183 GHz H2O line, a wide range of dense molecular gas tracers (HCN(2-1), HNC(2-1), HCO+(2-1), etc), CO(2-1) at 0.077<z<0.414, [C I] and high-J CO lines in high redshift objects, and eventually the [C II] line at z>8.

Memorandum of ALMA Operations: PI Data Delivery

Published: 16 Oct 2016

Memo from the ALMA Director and Operations Managers

The fundamental product of the ALMA Observatory is, and will remain, calibrated data and images. At the same time, the Observatory has been steadily increasing its performance in terms of efficiency, stability and time available for PI-driven science and, as a result, a steady increase in data production. We, at ALMA, aspire to maintain the quality of the delivered data. In the short-term, this will imply some extended data delivery timescales as the Observatory copes with the increased data load and the calibration and imaging pipeline matures to routine and more automated processing.

Impressions from the ALMA Postdoc Symposium

Published: 14 Oct 2016

Following the main ALMA conference "Half a Decade of ALMA: Cosmic Dawns Transformed" held in Palm Springs (California) from 20 to 23 September 2016, the 2nd ALMA Postdoc Symposium took place during the weekend of 24/25 September. More than 15 postdocs working for the different ALMA Regional Centers gathered together to share their scientific research and knowledge about the different activities related to ALMA. This time, a number of postdocs not directly associated with the ALMA Regional Centers but working with ALMA data were invited to participate and join the discussions.

UK ALMA "Bring Your Own Data" Workshop

Published: 10 Oct 2016

The UK ALMA Regional Centre Node would like to invite UK ALMA data users to a data reduction/processing event at Jodrell Bank Centre for Astrophysics (UoM campus) to be held on 21 - 25 November 2016. The focus of the workshop is to explore and to work on either own ALMA data or archival data with the assistance of UK ARC Node personnel and ARC Node computing resources.
