Attempting the Impossible: Taking the First Picture of a Black Hole

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.

Mission impossible per l’Event Horizon Telescope

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

Scientists to image event horizon of black hole

The European Research Council (ERC) has awarded 14 Million Euros to a team of European astrophysicists to construct the first accurate image of a black hole. The team will test the predictions of current theories of gravity, including Einstein’s theory of General Relativity, The funding is provided in the form of a “Synergy Grant”, the largest and most competitive type of grant of the ERC.
