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.

Below you can read the latest Announcements from the European ARC Network.. More details and up-to-date information can be found in the News section and the ALMA Science Portal.

Webinar on the distributed peer review process

Published: 26 Apr 2022

The Proposal Handling Team is organising a series of online sessions in which they will present the Cycle 9 distributed peer review process and guidelines for reviewing proposals. The sessions will consist of a presentation followed by a live question and answer session. Sessions targeted to the European community will take place:

Thursday May 05, 13:00 UTC   and  Tuesday May 10, 15:00 UTC.

CalMS Service approaching the 2000 MOUS mark with new features

Published: 26 Apr 2022

Since Oct 2019, the EU ARC is offering its users the "CalMS" service which has so far provided 155 unique users with more than 1750 calibrated MeasurementSets (MSs). As its popularity increases, further features are added to the system. Users can now:

  • immediately produce line images and cubes making use of the continuum subtraction performed by the pipeline,
  • request the calibrated data for particular calibrator targets,
  • identify MOUSs which belong to the same Group OUS.

New development study to investigate the potential of ALMA Advanced Data Products

Published: 26 Apr 2022

Current ALMA products can be characterized as "science-ready calibration, informative imaging". This means that PIs and archive users may need to repeat the imaging process to obtain products that are optimised for their specific scientific analysis. The purpose of this new development study is to investigate the potential interest of generating "science-optimised" products. These Advanced Data Products may include:

  • science-grade products for every ALMA observing project;
  • high-level science products based on, e.g., the combination of different observations of the same object;
  • derived products such as catalogues, spectra, SEDs, etc.

ALMA recounts of cosmic conundrums: How and when does planet-formation happen in disks?

Published: 10 Apr 2022

The next talk of the series will be presented by Davide Fedele (INAF Osservatorio Astrofisico di Arcetri), on May 4th at 14:00 CEST, who will address the question: How and when does planet-formation happen in disks? The talk will be broadcast on the Youtube channel of the European ALMA Regional Centre network.
