The first 60000 data cubes and continuum images generated by the Additional Representative Images for Legacy (ARI-L) ALMA development project are now available to download from the ALMA Science Archive (ASA). In addition to the primary-beam-corrected images, the released products also include the primary beams, and mask for all targets and calibrators of more than 1200 Cycle 3 and 4 datasets.

ALMA started the ‘Operation Support Facility (OSF) Ramp-up phase’ on 21 October. During this phase, the focus of the recovery is on returning to normal services at the Operations Support Facility, including food service, opening of labs and offices, and the confirmation of the stability of critical services.

On December 3 and 4 the ALMA Helpdesk will migrate to a new service provider, Deskpro. The new Helpdesk system will have the same functionality as the current system, but with a refreshed user experience for the ALMA user when creating tickets and interacting with the knowledgebase. We are confident that the new system will further improve the value of the Helpdesk in supporting exciting ALMA science!

Because of the migration to the new service provider the ALMA Helpdesk may be down during parts of December 3 and 4.

The UK ARC Node hosted its first virtual ALMA workshop for new postgraduate students during a series of half-days from the 9th to the 13th of November 2020.  This workshop covered the same topics that are featured in typical introductory ALMA workshops, including introductions to ALMA and interferometry, hands-on work with the Observing Tool and the ALMA Science Archive, and calibration and imaging in CASA. The difference was that this workshop was conducted entirely virtually, which presented some new challenges in terms of interactions with the participants, particularly in terms of troubleshooting problems. However, by the end, the participants succeeded in making their own ALMA images.

Dear colleagues,

The past several months have been an extraordinary period as a result of the global coronavirus pandemic. Everyone at ALMA hopes that you and your families are safe and healthy, and we extend our thoughts to those who have been directly affected by the pandemic.

For six months, almost the whole ALMA site has been shut down – power, water treatment, and running water - with only a single piece of key equipment (the hydrogen maser) still powered and checked daily as one of the tasks of the ALMA Caretaker Teams  - the teams who have ensured the safety and security of the ALMA Observatory through the shutdown.   

With the improving pandemic situation in Chile, ALMA is now scheduled to begin the long process of recovering the telescope array in the Atacama on October 1^st, 2020, starting with preparation of the ALMA Operations Support Facility (OSF) at 2900 metres for the return of staff and contractors.

The road to recovery of operations, and ultimately science observations – a milestone that will not take place this year - has been carefully planned. It is difficult to predict the exact timeline since several aspects of the plan depend on prevailing conditions not under our control. However, the following describes the current plan of activities and schedule for the return of ALMA to science operations.

The European ALMA Regional Centre invites all European ALMA users to a short virtual community assembly on October 8 at 10:00 CEST. After a long period of suspended science observing, there is now a path towards getting back on sky and collecting science data with ALMA again. At this community meeting, we will update you on the time line for recovery and can answer any questions you may have on your ALMA projects and support from the European ARC network.

Reserve the date: 8 October at 10:00 CEST. The meeting can be accessed at this link. Looking forward to seeing you then!

It has been a while since ALMA antennas have pointed towards the sky. Many of you have used this time to mine the ALMA archive, do great science, think of future projects and contemplate about your past experience with ALMA data and the services, tools and user support offered since Cycle 0.

While the antennas are taking an unanticipated break, ALMA is launching a new global project to Redesign the User eXperience (RedUX). As part of RedUX we will establish focus groups to discuss specific aspects of the ALMA user experience. By volunteering to join a focus group, you can help shape the future of ALMA. If you are interested in contributing to RedUX (and in receiving a small gift at the end of the exercise, as a token of our appreciation for your contribution), please fill in this form. The form is not anonymous, as we need your contact details in order to be able to get in touch with you.

The ALMA Spectroscopic Survey in the Hubble Ultra Deep Field (ASPECS) is a 3D survey of gas and dust in distant galaxies. It focuses on the best-studied cosmological deep field, the iconic Hubble Ultra Deep Field. Capitalizing on the unparalleled sensitivity of ALMA the ASPECS data unveil reservoirs of molecular gas and dust in galaxies up to redshifts z~4, when the Universe was only 1/8th of today's age. This interstellar medium constitutes the matter out of which stars form, and it is thus a prerequisite of the star formation process, and thus a key driver for galaxy evolution. The ASPECS data - that can be obtained from this page - provide the most sensitive image of the sky at 1.2 mm available to date, disclosing the emission of dust, which is heated up by the star formation.
