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.

New ALMA Europe social media channels

Published: 17 Feb 2020

The ARC network now has a social media presence! We aim to report on everything from insider information on the latest European ALMA results to life at the nodes, reports from both technical and scientific meetings and workshops, and exclusive insights into what it's like to be an (ALMA) astronomer. Come and join us on Facebook (@ALMAEUARC), Instagram (@alma_europe) or Twitter (@ALMA_Europe)!

Items for planning Cycle 8 proposals

Published: 10 Feb 2020

The ALMA call for Proposals for Cycle 8 is soon approaching. As previously announced, the ALMA Proposal Review Process for Cycle 8 will use a dual-anonymous procedure. The guidelines are given here. The ALMA configuration files to be used in simulations for Cycle 8 proposals are the same as those provided for Cycle 7, noting that the longest baseline configurations C43-9 and C43-10 will not be offered. Any remaining questions regarding the planning for Cycle 8 proposals can of course be asked via the ALMA Helpdesk.

Cycle 7 ACA Supplemental Call Results

Published: 16 Jan 2020

The deadline for submission of ACA Cycle 7 supplemental proposals was 1 October 2019. There were 249 proposals recieved with a request totalling 8199 hours, vastly exceeding the anticipated 2500 hours to be offered. This was the first call to use the distributed peer review system at ALMA. There were 99 projects accepted with a total of 3069 hours observing time. In addition 1294 hours of Total Power time was also accepted. The proposal acceptance rate was independent of time requested per project, which ranged from a few hours up to ~150 hours per proposal. Band 3 and 6 were the preferred bands of choice. For more details see the offical report.

ALMA Cycle 8 Pre-announcement

Published: 20 Dec 2019

The Joint ALMA Observatory (JAO) will start the next cycle of observing (Cycle 8) in October 2020.

A Call for Proposals with detailed information on Cycle 8 will be issued in March 2020, with a deadline for proposal submission mid-April 2019. This pre-announcement highlights aspects of the Cycle 8 proposal call that are needed to plan proposals. More information can be found on the ALMA Science Portal.
