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.

EU request for calibrated data

Published: 20 Sep 2019

By popular demand, the EU ARC has implemented a service which permits ALMA users to request the calibrated data for a given dataset (Member Obs Unit Set, MOUS) to be made available for download. The service is open both for ALMA PIs or Delegees with proprietary ALMA data and for archival users wanting to use datasets for which the proprietary time has expired.

ALMA Cycle 7 ACA Supplemental Call for Proposals

Published: 09 Sep 2019

The Supplemental Call is open to Regular Proposals (i.e., no Large Programs) without time constraints that propose to use standard observing modes, as allowed for ACA stand-alone proposals in the Main Call. Proposals may request to use the 7-­m array only or the 7­-m array plus Total Power array. It is anticipated that approximately 2500 hours on the 7-m array will be scheduled in the Supplemental Call. For more information please visit the dedicated ACA Supplemental Call page.

The new ALMA interface query tool

Published: 29 Jul 2019

Welcome, the new as-fast-as-you-type query interface for the ALMA. This amazing new ALMA query interface features the classical result table, in addition to an expanded view of the observations on-the-sky through AladinLite, as well as a totally new viewer to visualize the spectral coverage of the observations - all in one easy to use package.

Phase II submission is now open

Published: 26 Jul 2019

The Phase II submission period is now open for all PIs to submit the science goals of their accepted Cycle 7 projects. The Observing tool has also been updated with the Phase II version. Your project may also be required to pass a technical feasibility assessment as part of the Phase II process in order to be added to the observing queue. Further information on the Phase 2 process, including how you can delegate the Phase II preparation to one of your colleagues, is available in the Phase II Quickstart Guide at http://almascience.org/documents-and-tools/cycle7/phaseii-userguide.

ALMA Cycle 7 PI survey

Published: 26 Jul 2019

Subsequent to the ALMA Cycle 7 proposal result outcomes, ALMA kindly requests the participation of all PIs to submit feedback on the consensus reports received informing them of their ALMA Cycle 7 results. One survey should be completed per proposal submitted.

The surveys are strictly confidential and anonymous, but provide the means to gauge and improve the reviewing process. The deadline for completing the survey is 5 September 2019. To complete your survey please follow the link here.
