ALMA joins the Global Millimeter VLBI Array (GMVA) and the Event Horizon Telescope (EHT)

The Atacama Large Millimeter/submillimeter Array (ALMA) joins for the first time the Global mm-VLBI Array (GMVA) and the Event Horizon Telescope (EHT), Earth-sized virtual observatories, which are made possible by an international collaboration of radio telescopes. One of the main drivers of this global collaboration is to study in detail the supermassive black hole at the center of our Milky Way. The GMVA will derive the properties of the accretion and outflow in the immediate surroundings of the Galactic Center, while the EHT will aim at imaging, for the very first time, the shadow of the black hole’s event horizon.

È tutto pronto per scattare la foto del secolo. Un insieme di otto osservatori simulerà un radiotelescopio delle dimensioni della Terra allo scopo di intravedere il moto del gas incandescente che circonda il buco nero supermassiccio della Via Lattea. Quali le sfide e le attese? Ne parliamo con Heino Falcke, presidente del consiglio scientifico dell’EHT, e Ciriaco Goddi, responsabile scientifico del progetto BlackHoleCam

The Vice Chancellor of the University of Namibia, Prof. Lazarus Hangula and Prof. Gerard Meijer, president of the executive board of Radboud University, signed a Memorandum of Understanding today. This collaboration is a further step in the internationalisation of the Radboud University and a step in the development of research education in Africa.


This agreement will form the basis for further cooperation in various academic fields. As a first step, the universities want to collaborate on astronomical instrumentation as Namibia provides excellent observing conditions for astrophysical research.


Under the agreement, the universities will consider an exchange of academic staff, including Bachelor (Honours), Master, and Doctoral research students, for the purpose of joint research and teaching. To grow the partnership the universities will be organizing conferences, symposia, seminars, summer school courses, workshops, and public lectures and outreach efforts.

New telescope

The department of astrophysics is currently investigating possibilities to put a new radio telescope on a high mountain in southern Africa – the African Millimetre Telescope (AMT). The telescope shall participate in high-resolution imaging of cosmic radio sources, such as black holes and star forming regions. The agreement now provides the frame work to develop this project further in a joint effort.

In order to finance the telescope Radboud University has put in place a fundraising team to attract private investors.

University of Namibia

The University of Namibia (UNAM) currently services 24,000 students spread over 12 campuses throughout the southern African nation of Namibia and is the premier academic institution in that country. The Department of Physics within the Faculty of Science is currently expanding its astrophysics and astronomy group and is actively participating in the High Energy Stereoscopic System (H.E.S.S.) from its inception, the Cherenkov Telescope Array (CTA), the Square Kilometre Array (SKA) and the African VLBI Network (AVN).

Een internationaal team van onderzoekers gaat proberen de waarnemingshorizon van een zwart gat te fotograferen en zo eindelijk doorslaggevend bewijs leveren dat zwarte gaten bestaan en al dan niet werken zoals Einstein voorspelde.

Bestaan zwarte gaten? Het lijkt misschien een rare vraag. Er zit er toch één in het hart van onze Melkweg? Read more
