ALminer: ALMA archive mining and visualization toolkit

It is our pleasure to announce the release of ALminer: ALMA archive mining and visualization toolkit!

ALminer is a novel Python-based code that enables users to efficiently query, analyse, and visualize the ALMA Science Archive. Users can programmatically query the archive for positions, target names, or any other keywords in the archive metadata (e.g. proposal title, abstract, scientific category) in a simple way. ALminer’s plotting routines allow the query results to be visualised, and its analysis functions allow users to filter the results and check whether certain frequencies of interest are covered in the queried observations. The code also allows users to directly download ALMA data products in FITS format and/or the raw data that can be used for manual image processing. ALminer has been designed to make mining the ALMA archive as simple as possible, while being flexible to be customised according to the user’s scientific interests. The code is released with a detailed tutorial Jupyter notebook, introducing ALminer’s common functions as well as some of its more advanced options.

For more information about how to install and use ALminer, please visit the documentation or GitHub pages.

ALminer is a collaboration between Allegro, the ALMA Regional Centre in The Netherlands, and the University of Vienna (Austria) as part of the EMERGE ERC-StG project. With the public release of this new software, our goal is to provide the astronomical community with a new easy-to-use toolkit that facilitates the scientific exploitation of the rich ALMA science archive.

If you use ALminer as part of your research, please consider citing Ahmadi & Hacar 2021.

For suggestions and collaborations, please e-mail Aida Ahmadi.

I-TRAIN: ALMA Training Sessions

The European ARC Network is offering a series of online topical training sessions focused on the analysis of ALMA and interferometric data in general. The sessions will cover a wide range of topics of interest to the ALMA user community with the aim to help users gain expertise in working with interferometric data. Each training session will be one hour long and will include a live demo and an interactive Q&A section.

The following is a list of training sessions currently being offered. We will update this page as more sessions are offered. Click on each topic for more information about how to participate.

  1. Imaging with the ALMA Pipeline (December 4, 2020 – 11:00 CET)
  2. ALMA Science Archive update and ARI-L (December 15, 2020 – 11:00 CET)
  3. UVMultiFit: a versatile library for fitting models directly to visibility data (January 15, 2021 – 11:00 CET)


New Allegro Program Manager: Violette Impellizzeri

We are excited to announce that Violette Impellizzeri has joined Allegro as our program manager!

Violette received her PhD in 2008 at the Max Planck Institute for Radioastronomie in Bonn, on the topic of “molecular tori in the core of AGN”. After her PhD, she moved as a postdoc to NRAO, in Charlottesville, to work on the Megamaser Cosmology Project. It was during this time that the ALMA telescope began construction, and as NRAO was one of the ALMA partners, she soon became excited at the idea of being part of such an important project and furthering her interferometry interests. For this reason, in 2011 she moved to the Joint ALMA Observatory (JAO) in Chile as a commissioning postdoc and science fellow; during commissioning she also worked on early VLBI testing, science verification, and high frequency observing techniques. In 2014, once operations began, she was hired as an operations astronomer taking on new tasks such as the Phase II Group (P2G) Lead, ‘friend of VLBI’ and Proposal Handling Team (PHT) lead. On October 1st, she joined the Allegro ARC Node in Leiden, taking on the role of Program Manager, and is very excited to be returning to Europe and connecting with the Allegro team and the ALMA scientific community in The Netherlands.

We look forward to working with Violette and wish her all the best.

European ALMA Regional Centre Community Assembly

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 timeline 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.

Don’t hesitate to e-mail Allegro in case of questions, comments, or concerns. Looking forward to seeing you then!

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.

The future of ALMA support at the 42nd ESO Users Committee

The ESO Users Committee (UC) annual meeting will take in Garching on 26-27 April, 2018. Each year the UC meeting has one session dedicated to a special topic. In 2018 this special topic is the future of ALMA User Support.

Therefore, the feedback from EU ALMA users would be particularly important. The UC has prepared a poll to receive the feedback from the community at the following link:

The poll will be active until **March 26th, 2018**.

The UC also welcomes input through the national contacts. You can find more details in the following announcement:

Powerful New Hardware Approved for ALMA

The development of a new spectrometer for the Morita Array, which forms part of the Atacama Large Millimeter/submillimeter Array (ALMA), has been approved by the ALMA Board. Developed by Japan, the Morita Array is composed of twelve 7-metre antennas and four 12-metre antennas.
