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 Cycle 8 2021 Pre-Announcement

Published: 17 Dec 2020

The Joint ALMA Observatory (JAO) is planning to start the observations for Cycle 8 2021, in October 2021. A Call for Proposals (CfP) with detailed information on the new cycle is anticipated to be issued in March 2021 and the deadline for proposal submission will be in April 2021. The purpose of this pre-announcement is to highlight aspects of the CfP to assist with early planning. It also contains information related to the proposal review process. 

Second European ALMA Regional Centre community assembly

Published: 10 Dec 2020

The European ALMA Regional Centre invites all European ALMA users to a virtual community assembly on December 18 at 11:00 CET, following the pre-announcement for Cycle 8 2021, scheduled for December 17. At this community meeting, the ALMA director will present the latest on the Return to Operations. You will then be presented with the timeline for the Call for Proposals, the capabilities and changes in the reviewing process for Cycle 8 2021. Finally, you will have the opportunity to ask your questions on all the above in a dedicated Q&A session.

Reserve the date: 18 December at 11:00 CET. The meeting can be accessed at this link. Looking forward to seeing you then!



ALMA 2030: Development Study on Bayesian Adaptive Interferometric Image Reconstruction Methods

Published: 09 Dec 2020

The ESO internal ALMA development study "Bayesian Adaptive Interferometric Image Reconstruction Methods" officially started with a kickoff meeting occurred in December 2020. This study investigates the feasibility of artificial intelligence methodologies to refine the CASA package in view of the ALMA 2030 roadmap.

ALMA2030: Development study to design a wideband 200-400 GHz cold cartridge demonstrator kicks off

Published: 02 Dec 2020

A new development study, led by the Group for Advanced Receiver Development (GARD) at Chalmers University in Gothenburg, will complement the SIS process study to investigate the impact of a significant increase in the IF bandwidth on all the receiver components. 

ALMA2030: Development study to develop new SIS process kicks off

Published: 02 Dec 2020

A new development study, led by the Group for Advanced Receiver Development (GARD) at Chalmers University in Gothenburg, will develop new processes to fabricate small size SIS junctions, which are at the heart of the ALMA receivers. This fundamental technology development study aims to adapt the fabrication techniques to increase the instantaneous IF bandwidth of the receivers by a factor of 2 to 4, following one of the key recommendations of the ALMA Development Roadmap.
