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.

ALMA Proposal Preparation Day 2021

The ALMA Cycle 8 2021 Call for Proposals is now open with a submission deadline on April 21, 2021

The Allegro ARC Node would like to invite you to attend a proposal preparation workshop. The aim of this workshop is to assist you in making the most out of ALMA’s new capabilities, getting an overview of the new modes offered, and proposal preparation through the ALMA Observing Tool (OT). We will also offer guidance with writing double-anonymous proposals and in the new stages of proposal writing and reviewing (the “distributed proposal review process”) that will be in use from Cycle 8 2021.

The format of our workshop will be virtual, and it will consist of:

  1. a live online event with the Allegro team on March 29th with a few presentations and an extensive Q&A session
  2. online video tutorials that will be uploaded after the online event (watch last year’s video tutorials here)
  3. online drop-in sessions on Wednesdays 14-15 and Fridays 9-10
  4. individual 1-1 support that can be booked at any time (e-mail us)

Our online event will be used to address questions related to proposal submission and the distributed proposal review process that will be adopted from Cycle 8 2021 onwards. Since proposals will have to be written in a fully double-anonymous fashion this year, the Allegro team will provide advice on how this can be achieved, and explain how one can refer to unpublished data and previous ALMA projects without accidentally violating the double-anonymous guidelines.

You can register to attend the online event on March 29th using this registration form.

An overview of important dates and what’s offered in Cycle 8 2021 can be found in the Call for Proposals. As a reminder, the Cycle 8 2021 will include configurations from C-1 up to C-8, with a special focus on high frequency observing. New capabilities that will be offered include Solar observations in Band 5, a passive-phasing mode for VLBI, high-frequency observations (Bands 9 and 10) with the stand-alone 7-m array, mosaicking of continuum line polarisation observations (Bands 3 to 7), spectral scans with the 7-m Array and up to 75 hours of full polarisation observations of a single field with the 7-m Array. No long baseline observations are offered in Cycle 8 2021.

We look forward to seeing many of you at the ALMA Proposal Preparation Day on March 29th! Meanwhile, don’t hesitate to e-mail us if you have questions, concerns, or need support. We would be happy to set up a remote meeting with you. PIs who are considering a Large Program are especially encouraged to contact Allegro early so we can explore the many ways we can support your project and help optimize your program.

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.

ALMA Proposal Preparation Day (online material)

IMPORTANT UPDATE: The ALMA Director, along with the regional partners, have decided to delay the proposal deadline for the ALMA Cycle 8 Call for Proposals to NO EARLIER than 15 UT on 19 May, 2020. Therefore, Allegro has decided to postpone the Proposal Preparation Workshop of March 26 to a later date, approximately 3 weeks before the actual deadline (when this is decided).

For those who want to get started on their ALMA proposal still on the original schedule, we are providing a series of pre-recorded presentations:

which can be found below or on our YouTube channel.

Everyone is encouraged to e-mail Allegro with any questions that they may have after watching these presentations. We will answer all questions, either by e-mail or via an online session, and also collect Frequently Asked Questions in a constantly updated document. For your convenience, we have also created a toolbox with useful links to help you prepare your proposal.

We would like to highlight the possibility to submit Large Programs on both the main array (>50 hours) and ACA stand-alone (>150 hours). PIs who are considering a Large Program are encouraged to contact Allegro early to optimize your program and explore the many ways we can support your project.
