A study by the Group for Advanced Receiver Development (GARD, Sweden) to develop new fabrication technology for sub-micron size Aluminium Nitride (AlN) barrier Superconductor Insulator Superconductor (SIS) junctions has been successfully completed. These SIS junctions are at the core of most ALMA receivers where the sky signal is mixed with the Local Oscillator to tune the receivers to the desired frequency. 

A development study aimed to validate and improve the current atmospheric radiative transfer model implemented for ALMA (atmospheric transmission model, ATM) has been successfully completed. The model is important for both planning and helping in the calibration of ground-based observations at millimeter and submillimeter wavelengths.

The ALMA Observatory is starting the release process of the data acquired in one of the Observatory Projects, 2022.A.00034.S.

ORP (Opticon Radionet Pilot) funding remains available till the end of 2024 for travel to one of the European ALMA Regional Centre nodes in Europe, for ALMA users who need face-to-face support for their ALMA projects. Users wishing to apply for ORP funding should fill out the form in addition to submitting a Helpdesk ticket that is required to arrange the ARC node visit. Face-to-face visits to ARC nodes can be arranged for assistance with data calibration and analysis, proposal preparation, and archive research projects.

This announcement provides updated information regarding the Cycle 11 Call for Proposals (CfP) deadline submission issues experienced by some ALMA users. 

Since the start of ALMA operations, the Nordic ARC node has enthusiastically organised annual events to support the ALMA user community with their proposal preparations. Over the past couple of years, the node has also arranged an annual event to foster collaboration and engagement among ALMA users in Sweden and other Nordic countries, which has now started to be called "The Nordic ALMA Day". One of the main aims of this event is to bring together astronomers and researchers to share insights and discuss topics relevant to the ALMA user community.

A new ALMA development study to automatically extract spectral line sources from ALMA data cubes and derive advanced data products from them had its kick-off meeting on 3 June 2024 in Gothenburg (Sweden).
