Dutch researchers uncover hidden supermassive black hole
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…

First photo of black hole at the heart of our Galaxy
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.

Finding the origin of giant black holes
‘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 continues her search for the origins of the largest black holes, but now as a professor
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.’

Scientists discover the largest stellar black hole in the Milky Way
A European team of astronomers has discovered the largest stellar black hole in the Milky Way. It is more than thirty times as massive as our sun and is located in the constellation of Aquila, about two thousand light-years from Earth. The astronomers stumbled upon the black hole by chance while preparing…

Black holes are sometimes gigantic volcanoes. Martijn Oei earned his PhD on the subject, with honours
Not everything that comes close to a black hole is swallowed by it. Black holes can also hurl material away, and that chance turns out to be considerably bigger than previously thought. Martijn Oei's accidental discovery and his subsequent research on it earned him a cum laude promotion on 12 Decemb…

How the speed demons of the universe tell us something about the Milky Way
They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.

Motion of stars near Milky Way's central black hole is only predictable for few hundred years
The orbits of 27 stars orbiting closely around the black hole at the center of our Milky Way are very chaotic. As a result, researchers cannot predict with confidence where they will be in about 462 years. ‘That is astonishingly short,’ says astronomer Simon Portegies Zwart who collaborated on the r…

Willem van der Does sheds new light on the at times pitch-black history of psychiatry
Piercing through the skull with an ice pick, administering electric shocks without an anaesthetic, or applying leeches to the uterus: these may seem like medieval methods of torture, but they are in fact therapies used in medicine. Willem van der Does writes about all of them in his new book. ‘Physicians…

Sjoert van Velzen receives Vidi grant to solve 'riddles from the universe'
Minuscule elementary particles from space colliding with Earth can give us an insight into the distant objects they come from. But first, you need to know how to catch them. With a Vidi grant from NWO, researcher Sjoert van Velzen will 'hunt' for neutrinos coming from exploding black holes.

Galaxies have bipolar gas outflows far into intergalactic space
For the first time, astronomers have observed in three dimensions that gas from spiral galaxies is blown upwards and downwards at high speed, far out of the galaxy. They thereby confirm the theory of galaxy evolution: that star-forming galaxies create intergalactic gas flows by discharging gas along…
