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.’

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.

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…

We are proud partner of the ULLA. It is the European University Consortium for Pharmaceutical Sciences in which LACDR participates for already 30 years. We have the honor to host the ULLA workshop in 2023 and the ULLA summer school in 2024.

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…

Leiden University wants to ensure you can do your work safely and with the right support. Here you will find information on who to contact in case of problems, questions, or emergencies, as well as answers to questions such as: What should I do in the event of a work-related accident? Where can I go…

Leiden University provides staff with a modern ICT environment to carry out their work efficiently and securely. Here you will find more information regarding technical support, manuals, and contact persons, as well as answers to questions such as: Where can I report an ICT issue? How do I install software…

From Monday 19 July onwards, eighteen children between the ages of 10 and 12 are learning the programming language Hedy. In the Snellius building of Leiden University they will be taught the first principles of programming this week.

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…

Three student athletes from Leiden University are representing the Netherlands at the FISU Summer World University Games, a kind of Olympic Games for students.

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.

Eastern and Southern European countries struggle with ‘brain drain’ as skilled workers move to other EU Member States. Could restricting free movement be a legitimate and lawful way to address this trend? Researcher Martijn van den Brink will investigate the issue.

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…
