In April 2019, the Event Horizon Telescope (EHT) collaboration revealed the first image of the candidate supermassive black hole (SMBH) at the center of the giant elliptical galaxy Messier 87 (M87). This event horizon-scale image shows a ring of glowing plasma with a dark patch at the center, which is interpreted as the shadow of […]

La foto del secolo è stata finalmente mostrata dal team dell’Event Horizon Telescope. Ciò che è stato osservato ha dell’incredibile: una struttura ad anello consistente con le predizioni della relatività generale. Cosa implicano questi risultati? Abbiamo davvero aperto una nuova finestra nella ricerca di frontiera? Per saperne di più, a un mese dallo storico annuncio […]

For the first time, astronomers have managed to take a photo of a supermassive black hole and its shadow. They used the Event Horizon Telescope (EHT), a worldwide network of eight radio telescopes, that together form a virtual telescope the size of the earth. The news was presented in six press conferences around the world […]

L’Event Horizon Telescope, collaborazione internazionale che vede la partecipazione di centri di ricerca in tutto il mondo, svela oggi la foto del secolo. Due ricercatrici dell’Inaf, Elisabetta Liuzzo e Kazi Rygl, sono tra i protagonisti della rivoluzionaria osservazione del gigantesco buco nero nel cuore della galassia Messier 87, come parte del progetto BlackHoleCam. Un altro […]

An international collaboration presents paradigm-shifting observations of the gargantuan black hole at the heart of distant galaxy Messier 87. The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, […]

Including the powerful ALMA into an array of telescopes for the first time, astronomers have found that the emission from the supermassive black hole Sagittarius A* (Sgr A*) at the center of our Galaxy comes from a smaller region than previously thought. This may indicate that a radio jet from Sgr A* is pointed almost […]

At the centre of our own galaxy there is a black hole, called Sagittarius A*. In anticipation of the first actual photograph of a black hole, an international project  involving astronomers of BlackHoleCam, Jordy Davelaar and colleagues have built a virtual reality (VR) simulation of the phenomenon. The VR simulation was published in Computational Astrophysics […]

Measurement of the “Gravitational Redshift” in the Orbit of the Star S2 around the Supermassive Black Hole at the center of the Milky Way with GRAVITY eso1825 — Science Release – July 26, 2018 Obscured by thick clouds of absorbing dust, the closest supermassive black hole to the Earth lies 26 000 light-years away at the […]

The European Research Council has published a video about the BlackHoleCam project featuring the three Principal Investigators: Heino Falcke, Michael Kramer and Luciano Rezzolla. In case of any questions, please contact Katharina Königstein, Radboud University.

ALMA Observatory Facebook Live – Apr 19, 2018 Dr. Ciriaco Goddi, BlackHoleCam Project Scientist from Radboud University, is at the ALMA observatory  for the 2018 observing campaign of the Event Horizon Telescope. In this video, he explains what VLBI is, the interferometric technique to make very high-angular resolution images of radio cosmic sources, and which […]
