Black holes like to eat, but have a variety of table manners
All supermassive black holes in the centres of galaxies appear to have periods when they swallow matter from their close surroundings. But that is about as far as the similarities go. That's the conclusion reached by British and Dutch astronomers from their research with ultra-sensitive radio telescopes…

Greedy black hole feeds via two spiral arms
The supermassive black hole at the center of the Circinus galaxy is being fed with gas by two spiral arms. This is what PhD candidate Wout Goesaert discovered. But only a small percentage disappears into the black hole, the rest is ejected.

LOFAR antennas unveil giant glow of radio emission surrounding cluster of galaxies
A Dutch-Italian-German team of astronomers has observed a huge glow of radio emission around a cluster of thousands of galaxies. They combined data from thousands of LOFAR antennas that were focused for 18 nights on an area the size of four full moons. This is the first time astronomers have been able…

Astronomers see gigantic collisions of galaxy clusters in young universe
An international team of researchers led by Leiden University (the Netherlands) has mapped nine gigantic collisions of galaxy clusters. The collisions took place seven billion years ago and could be observed because they accelerate particles to high speeds. It is the first time that collisions of such…

Using a camera to look into a book's spine: ‘You might just find that one rare text’
What do you do if you have a book from the sixteenth or seventeenth century, but you suspect that the binding contains a fragment of a medieval manuscript? University lecturer Thijs Porck has received an NWO grant to experiment with a camera attached to a tube. 'The project boils down to keyhole surgeries…
