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.

ALMA Data Reduction Training

Published: 25 Nov 2022

Following the 6th Netherlands ALMA Science Day, on Friday, 9 December Allegro will host an introductory ALMA Data Reduction Training also at Leiden Observatory. Allegro fellows will introduce CASA and ALMA data reduction techniques, share tips & tricks, and offer extensive hands-on training in data imaging and analysis. Students and postdocs are particularly welcome to attend the training, which will cover both basics and more advanced topics. The registration form will remain open until 2 December 2022.

ALMA Update on the Recovery from the Cyber-attack

Published: 18 Nov 2022

On October 29, 2022, the Atacama Large Millimeter/submillimeter Array (ALMA) suffered a cyber-attack on its computer systems, forcing the suspension of astronomical observations and the public website. This event is under investigation by local authorities.The Computing team quickly isolated the Antennas and Correlator systems and the Science Archive data systems. However, communication and other operational clusters were affected, forcing ALMA to stop all observations. Since then, email communication has been restored safely, along with new collaboration tools that enable the staff to continue their regular work.

The Crisis Management Team has developed a full-recovery plan in consultation with cyber security officers from ESO/NAOJ/NRAO. Our highest priority is to work hard to resume observations before the end of the year.

The goals of the meeting are to allow the participants to present their scientific work, interact with other participants and staff working in the ARC nodes, and potentially trigger new collaborations and new projects. For details and registration, please visit this page

New CASA-related technical papers

Published: 05 Nov 2022

CASA is the designated science data analysis package for ALMA. An updated reference paper on this software, which is produced jointly by NRAO, ESO, NAOJ, and JIV-ERIC under the guidance of NRAO, was published this month together with a sister paper on the new VLBI processing capabilities of CASA.
