Survey: ALMA User Experience

The End-to-end User Experience Working Group are a team of staff from the different ARC nodes who are seeking feedback on how to improve the ALMA user experience, from the Call from Proposals stage, through working with ALMA data (be it a project you proposed or Archival data). The ultimate goal is to identify and address any issues which prevent the best user experience and affect scientific output. You can help us by filling in our survey at the following

Your feedback will be very much appreciated! You can also contact the ARC nodes in Europe directly if you want to discuss particular aspects of your user experience.

If you want to know more about the ALMA User Experience Survey in the Netherlands, please contact Allegro by sending your email to and/or

Changes to how to write your ALMA proposal for Cycle 8

For Cycle 8, ALMA is adopting dual-anonymous review. This means that the proposers do not know who the reviewers are, and the reviewers don’t know who is on the proposing team. This has important consequences on how you write your proposal!

ALMA has put together a document with guidelines. Consequently, any text that can identify the proposing team is not allowed. Attempts to convey the identify proposing team in the text may lead to your proposal being disqualified.

What you need to do:

  • Read the guidelines.
  • Write your new proposal according to these guidelines, and rephrase the text of proposals that are re-submissions from previous cycles.

A presentation describing how to write an anonymous ALMA proposal can be found below (pdf file).

Allegro is organizing a proposal preparation workshop on Thursday March 26, where these requirements will be discussed together with other technical information about ALMA Cycle 8. You can register for the Proposal Preparation Day at the following link.

ALMA-VLBI QA2 Workshop– Leiden Lorentz Center, 24-28 February 2020

Allegro is hosting a QA2 training workshop for phased-ALMA data acquired during VLBI observations, which will be held in Leiden (the Netherlands), on February 24-28 2020.
VLBI is an observing mode offered since Cycle 4, and the first observations were conducted in Apr 2017. The QA2 process for VLBI projects is significantly more complex than the procedure for standard projects, requiring a close loop between ARCs, JAO and VLBI correlators.
The main goal of the workshop is to train ALMA astronomers so that the QA2 work load can be distributed across different regions. The training workshop will involve hands-on work on past cycles datasets.
This workshop is restricted to the trained QA2 analysts in ALMA Regional Centers (ARCs).

EAS2020 – Special Session Nr. 13: Eight years of ALMA ground-breaking results.

We would like to bring to your attention the special session ‘Eight years of ALMA ground-breaking results: A joint venture between the ALMA user community and the ALMA Regional Centres‘ that is organised as part of the yearly meeting of the European Astronomical Society. The conference will take place in Leiden, The Netherlands, on June 29 – July 3, 2020. The Special Session No. 13 will be held on the last day of the conference (July 3rd).

The Special Session SS13 will focus on scientific results that emphasise the connection between the ALMA users and the EU ARC network, and include:

  • Scientific highlights from large programs.
  • Scientific results from special modes with EU-specific strengths:
    high frequencies, polarization, solar observations, deep fields, data combination.
  • Results based on archival research and data mining.
  • Community and EU ARC network software/tools development.
  • Optimization of observations setup and data calibration.
  • Computing facilities for data reduction and analysis.

For more information on the SS13, please visit this link.

For general information on the EAS 2020, please click here.

Abstract submission is open for the SS13 in a form of oral or poster presentations. In order to submit your abstract, please visit the Abstract portal:

Conference:Resolving the Extragalactic Universe with ALMA

There is an open call for applications to the conference “Resolving the Extragalactic Universe with ALMA” to be held November 9-13, 2020, focused on the latest scientific results on the high-redshift universe with the ALMA telescope.

The primary scientific themes are:

• High-z galaxies and quasars, the epoch of reionization.
• High-spatial resolution studies: Galaxy kinematics, outflows, mergers, etc.
• Blind surveys — The unknown.
• Simulations of high-z galaxies.
• Physical conditions in high-z galaxies: Gas mass, dust temperature, SFR, etc.

The Conference will be held at Waseda University (Shinjuku, Tokyo) with a 1-day working excursion to Kamakura. If you wish to attend (space is limited), please apply here

Requesting calibrated data in Europe

from 1 October 2019 onwards

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.

If you have identified a particular MOUS that you want to investigate, please file
a normal Helpdesk ticket in the department “Archive and Data Retrieval (EU)” and
select the “Data request” sub-category.

In the body of the text always specify the project code (e.g. 2015.1.09999.S, one per ticket)
and MOUS UID(s) (e.g. uid___A001_X340_X6 or uid://A001/X340/X6). You can
enumerate up to 10 MOUSs in your request.

The creation and staging will be done one MOUS at a time and you will be notified
*by separate email for each MOUS* as to where you can download the tarred MS(s).
Depending on the workload on the EU ARC systems, it may take days before your
dataset is ready for you.

Your download link will remain valid for 28 days, which means that you have 28 days from the time
of the notification email to download the data.

The service will become available on 1 October 2019.

Netherlands ALMA Science Day — 22 November 2019.

Allegro is organizing an ALMA Science Day on Friday November 22, 2019, at Leiden Observatory.

ACA Supplemental Call for Proposals

The Joint ALMA Observatory (JAO) is now accepting observing proposals for Cycle 7 that request to use the Atacama Compact Array (ACA) in stand-alone mode. Instructions on how to submit proposals can be found on the Cycle 7 Supplemental Call web page.

Users of any nationality or affiliation are invited to submit proposals before the deadline of 15:00 UT on Tuesday 1 October 2019.

Proposals submitted in the Supplemental Call will be peer-reviewed using a distributed system in which each proposal team selects a designated reviewer to participate in the review process. The review process is described in detail in the Supplemental Call documentation.

Users should note that the Supplemental Call proposal submission server will not be available for a few hours on September 10 and September 25 because of scheduled maintenance. The precise downtimes will be noted on the Science Portal. Users will need to update the Observing Tool (OT) after the September 10 maintenance period. For most users, this will happen automatically using the automated web start tool. Information on updating the OT is available at the Observing Tool webpage.

ACA Supplemental Call for Proposals Pre-announcement

The Cycle 7 Supplemental Call for Proposals is anticipated to open at 15:00 UT on September 3 with a proposal deadline of 15:00 UT on October 1. ALMA expects to allocate approximately 2500 h of observing time on the ACA in the Supplemental Call.
Preliminary information is currently available here.
Complete details of the Supplemental Call will be posted on the ALMA Science Portal on September 3.
