Astronomers have spotted signs of a ‘hot spot’ orbiting Sagittarius A*, the black hole at the centre of our galaxy. The finding helps us better understand the enigmatic and dynamic environment of our supermassive black hole.
Conny Aerts, professor of astronomy at Radboud University and KU Leuven (Belgium), was selected today by the Norwegian Academy of Science and Letters to share the Kavli Prize 2022 in astrophysics, the highest award an astrophysicist can receive after the Nobel Prize.
Astronomers have unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the centre of most galaxies.
A team of astronomers led by Peter Jonker (SRON/Radboud University) has now discovered that these seemingly disparate results can be explained by biases against massive black holes in conventional telescope observations.
Analyzing observations of an X-ray flare and fitting the data with theoretical models, Radboud University and University of Arizona astronomers documented a fatal encounter between an unlucky star and an intermediate-mass black hole.
On 7 September, prof. Heino Falcke will receive the Amaldi Medal (European Prize for Gravitation) 2021 from the Italian Society on General Relativity and Gravitation (SIGRAV). Falcke is awarded this medal for his extraordinary contribution to research on gravity.
Our colleague Professor Conny Aerts (Radboud and KU Leuven) has just been appointed Honorary Doctor at Aarhus University. Aarhus University awards honorary doctorates to "eminent researchers from other institutions with whom Aarhus University has a history of collaboration.”We proudly congratulate Conny with this well-deserved honor!
An international team anchored by the Event Horizon Telescope (EHT) Collaboration, which is known for capturing the first image of a black hole in the galaxy Messier 87, has now imaged the heart of the nearest radio galaxy Centaurus A in unprecedented detail.
