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.

An international team of astronomers led by Matus Rybak (Leiden University) has proven, thanks to accidental double zoom, that millimetre radiation is generated close to the core of a supermassive black hole. 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?

The brightness peak of the ring around M87's supermassive black hole has shifted 30 degrees counterclockwise in a year. This is shown by new images released by the Event Horizon Telescope consortium.

An international team of astronomers led by Dutch scientist Martijn Oei has discovered the largest pair of jets from a black hole ever seen. The 'jumbojets' extend a combined length of 140 Milky Ways. The Leiden Observatory played a prominent role in this research. The publication will feature on the…

50 years ago Lauterbur published the basic principle of MRI. Sine then MRI has become more expensive. Professor Andrew Webb describes what is needed to make MRI available for everybody.

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…

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…

Het zal niemand ontgaan zijn dat de digitale dreigingen blijven toenemen. Uit monitoring door onze cybersecurity-experts blijkt dat er continu wordt geprobeerd om ook onze systemen binnen te dringen. Wat doen wij daartegen en hoe kan jij als medewerker bijdragen aan onze cyberveiligheid?

‘A Muslim and a Jew in the house of God.’ This is how historian Nadia Bouras introduced her recent conversation with colleague Sara Polak in Leiden’s Hooglandse Kerk. They discussed the rising tensions since the outbreak of the Israel-Hamas war. ‘Dare to ask each other questions.’

Research

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…

At a celebratory event, 25 Leiden University projects received a Kiem grant of up to €10,000 for an interdisciplinary research or education initiative. The grant was in demand, as no fewer than 91 projects applied this year.

Una Europa, an alliance of 11 top European universities, provides annual seed funding for new research and teaching projects. Assistant Professor Carmen van den Bergh applied for funding with her Flemish and Italian counterparts. Thanks to this funding and the support of Erasmus+, students can now take…

It’s about much more than learning how to write a readable piece or give a presentation that doesn’t send the audience to sleep. The intensive Science Communication Summer School gives young scientists the chance to really make contact with the public.

An international team of astronomers, including Leiden PhD student Elia Pizzati, has observed several ancient quasars that, surprisingly, appear to be floating alone in the early universe (less than a billion years after the Big Bang). Until now, astronomers, based on models, assumed that quasars are…

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.
