Their findings have been accepted for publication in the journal Astronomy & Astrophysics.

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.

‘Space Antenna LISA will open an unprecedented window on the Universe,’ says astronomer Elena Maria Rossi. The mission will be the first one to detect Gravitational Waves from space. These can tell us more about the beginning of our Universe and the formation of black holes. With an NWO grant of twelve…

Elena Maria Rossi is fascinated by black holes. Her appointment as a professor was a long-held wish, partly because there are so few female professors in her field. ‘My appointment is also a milestone for the Leiden Observatory.’

How are supermassive black holes born? That is the question astronomer Elena Maria Rossi is trying to answer. But how do you investigate something you cannot see?

Studying abroad and going on an exchange is a great way to broaden your horizons and explore new places, cultures, and fields of study. In addition to a full-semester exchange, there are many other possibilities such as a summer school or an internship. For example, Bart Geldermans, Public Administration…

An international team of astronomers led by Violeta Gámez Rosas (Leiden University) has observed a supermassive black hole hidden in a ring of dust. This discovery fits the idea that the so-called active centers of galaxies are much more similar than observations show, because the viewing angle from…

Finally we know for sure that there is a black hole at the centre of our own galaxy. Today, astronomers unveiled the first ever photo of Sagittarius A*, a super-massive object at the centre of the Milky Way. This picture could only be taken thanks to the cooperation of telescopes worldwide.
