New Band 2 ALMA receivers that will probe our cosmic origins successfully tested

Published: 14 Aug 2023

An international team of astronomers and engineers at the Atacama Large Millimeter/submillimeter Array (ALMA) have made the first measurements using new receivers installed on multiple ALMA antennas. The receivers allow to observe within the final frequency range — with wavelengths between 2.6 to 4.5 millimeters (67-116 GHz) — for which it was designed. Band 2 opens a new window into our cosmic origins, allowing measurements that reveal how distant stars and galaxies form, all the way down to the origins of planets and the building blocks of life.  

CalMS Service celebrates more than 3000 served MOUSs

Published: 11 Aug 2023

The demand for the European ARC CalMS service ( has been roughly constant since the beginning of 2023 at 100 MOUSs/month. The 3000th MOUS was served at the end of July 2023 (counting since January 2020). The service will continue as it is for the foreseeable future.

Job Advertisement: Postdoctoral Support Position at Allegro

Published: 06 Jul 2023

Allegro, the Netherlands node of the European ALMA Regional Centre (ARC) at Leiden Observatory, invites applications for one or more postdoctoral support position(s). The position offers the opportunity for research at one of the major centres of astronomy in the Europe as well as an in-depth involvement in the development and operations of ALMA.

ALMA school pre-announcement

Published: 21 Jun 2023

The European ALMA Regional Centre network is organising an ALMA School for ALMA users, hosted by the UK Node on 10th - 14th June 2024 in Manchester. The school is designed to provide training on a broad range of aspects related to ALMA, including interferometry, data calibration and imaging, the ALMA archive, analysis techniques, ALMA science and future ALMA developments.

OT issue affecting Cycle 10 proposals requiring ACA observations

Published: 29 Apr 2023

An issue has been discovered in the Cycle 10 ALMA Observing Tool (OT) that affects the estimated Atacama Compact Array (ACA) integration times for some 4x4-bit ACA observations (7-m and TP). We have fixed this problem and a patched version of the Cycle 10 OT is now available on the Science Portal. All PIs of projects that include ACA observations should download the updated OT version and submit or resubmit their proposals using this version. The correct version can be identified by checking for the words "Patch 1" in the title bar at the top of the OT window.

ALMA Band 1 Capabilities at Cycle 10

Published: 28 Apr 2023

As described in the ALMA Cycle 10 Proposer's Guide, both spectral-line and continuum observations in Band 1 will be available only with the 12-m Array at Cycle 10, from March 2024 onwards. The Observing Tool will not prevent the submission of projects containing Band 1 ACA observations, but Band 1 ACA (7m and Total Power) observations are not technically feasible at this Cycle. Proposals requiring Band 1 ACA observations should therefore not be submitted.

ALMA Cycle 10 Call for Proposals

Published: 27 Apr 2023


On behalf of the Joint ALMA Observatory and the partner organizations led by NAOJ in East Asia, ESO in Europe, and NRAO in North America, the ALMA Director, Sean Dougherty, is pleased to announce the ALMA Cycle 10 Call for Proposals for scientific observations to be scheduled from October 2023 to September 2024. 

Proposal submission opens at: Wednesday, 12 April 202315:00 UT
Proposal submission deadline is: Wednesday, 10 May 2023, 15:00 UT  



ALMA at 10 years: Past, Present and Future

Published: 26 Apr 2023

As announced in the October 2022 EU ARC Newsletter, the ALMA partnership is organizing a conference to commemorate its first decade of science operations. The conference will take a look back at the observatory accomplishments, highlight its latest results and look forward to future technical developments. It will take place from 4 to 8 December 2023 in Puerto Varas, Chile. Abstract submission and registration for the conference is now open at the conference webpage with a deadline for abstract submission on the 31st of May 2023.
