Allegro, the European ALMA Regional Center node in the Netherlands

Allegro provides general user support for the ALMA community and offers expert help on high-frequency ALMA observations, synergy with radio astronomy, and science analysis tools.

Allegro integrates the expertise relevant to ALMA within the astronomical institutions and universities in the Netherlands. This includes the astronomy departments of the Dutch universities cooperating as the Netherlands Research School for Astronomy (NOVA), the Netherlands Foundation for Research in Astronomy (ASTRON), the Netherlands Institute for Space Research (SRON) and the Joint Institute for VLBI in Europe (JIVE).

News from ALMA

The cosmic weather report, as illustrated in this artist’s concept, calls for condensing clouds of cold molecular gas around the Abell 2597 Brightest Cluster Galaxy. The clouds condense out of the hot, ionised gas that suffuses the space between the galaxies in this cluster. New ALMA data show that these clouds are raining in on the galaxy, plunging toward the supermassive black hole at its centre.

Black Hole Fed by Cold Intergalactic Deluge

An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has witnessed a cosmic weather event that has never been seen before — a cluster of towering intergalactic gas clouds raining in on the supermassive black hole at the centre of a huge galaxy one billion light-years from Earth.


Allegro was established by Leiden Observatory, the Netherlands Research School for Astronomy (NOVA), and the Physical Sciences division of the Netherlands Organization for Scientific Research (NWO/EW). Funding is provided by NWO/EW.
