German ALMA Regional Centre (ARC) Node
The Atacama Large Millimeter/Submillimeter Array (ALMA) is a revolutionary interferometer for mm and submm astronomy in the Atacama desert in Northern Chile. It is operated by a global collaboration between Europe (ESO), North America (NRAO) and East Asia (NAOJ), in cooperation with Chile. The interface between ALMA and the user communities is provided by three ALMA Regional Centres (ARCs) in Europe, North America and East Asia.
The European ARC (EU ARC) is organized as a coordinated network with a central node at ESO Headquarters in Garching bei München and regional nodes located in Bologna(I), Bonn/Cologne(D), Grenoble(F), Leiden(NL), Manchester(GB), Ondrejov(CZ), and Onsala(S). The concept and the implementation of the EU ARC network has been described in an article in the ESO Messenger (Hatziminaoglou et al. 2015, Msngr. 162, 24).
The German ARC node is a collaboration of the universities of Bonn and Cologne. Its headquarters are located at the Argelander-Institut für Astronomie in Bonn. The German ARC node provides services to ALMA operations, the local astronomical community and the general public:
- User support
- Technical development
- Operational support
- Training and Outreach to the Scientific and Public Community

ALMA2040 splinter meeting
On behalf of the initiative ALMA2040 and the German ARC node, we cordially invite you to participate in the next ALMA2040 meeting!During the annual meeting of the Astronomische Gesellschaft in Görlitz, the initiative ALMA2040 and the German ARC node will host a splinter meeting on ALMA2040 on Wednesday, 17 September 2025. This 1-day splinter meeting will explore the science opportunities that a radical upgrade of ALMA in the 2040s could enable. In the past decade, ALMA has revolutionized our knowledge in many research areas, from forming protostellar disks to molecular clouds in external galaxies to detailed studies of the ISM in the early universe, and enabled high-fidelity imaging at the highest angular resolutions, all with substantial contributions from the German community. Therefore, we invite presentations on exciting results across the full breadth of ALMA science from the solar system to the highest redshift objects observed. Further we invite presenters to provide a short vision on which kind of ALMA upgrade could push the frontiers in their field of research.
In addition to these contributed presentations, the splinter will provide an overview on the status of the ALMA2040 initiative and options for the German community to get involved.
For registration and abstract submission (deadline: 31 July 2025), please go to the AG registration page.
We hope to see you at the ALMA2040 splinter!
Eva Schinnerer and Stefanie Mühle
