Early universe bristled with starburst galaxies

In the first few billion years after the Big Bang, the universe contained far more so-called starburst galaxies than models predict. As many as 60 to 90% of the stars in the early universe appear to have been produced by ...

Astronomers take 'heartbeat' of black hole

A black hole gets a large corona before it emits jets. This is revealed, among other things, by the heartbeat graph that an international team of astronomers has made of a black hole and a star orbiting around each other. ...

Less powerful black hole blows environment clean after all

An international team of astronomers led by Dutch scientists has discovered that even a weak jet stream from a low-active black hole can be a kind of leaf blower to clean parts of a galaxy. The observed black hole removes ...

Simulating chaotic interactions of three black holes

Dutch student Arend Moerman (Leiden University, the Netherlands) has defended his thesis research on the simulation of chaotic interactions of three black holes. The simulations, which he carried out together with researchers ...

Dwarf galaxy catches even smaller galaxy

Astronomers know that the Milky Way grew by taking in smaller galaxies. But now, a team of Italian-Dutch researchers has shown that a small galaxy neighboring the Milky Way has in turn absorbed an even smaller galaxy from ...

Astronomers see dust disk around young super-Jupiter

An international team of astronomers led by scientists from Leiden University has for the first time characterized a dust disk surrounding a young super-Jupiter, which is either a giant planet or brown dwarf. They used so-called ...

EHT pinpoints dark heart of the nearest radio galaxy

An international team anchored by the Event Horizon Telescope (EHT) Collaboration, which is known for capturing the first image of a black hole in the galaxy Messier 87, has now imaged the heart of the nearest radio galaxy ...

First measurement of isotopes in atmosphere of exoplanet

An international team of astronomers have become the first in the world to detect isotopes in the atmosphere of an exoplanet. It concerns different forms of carbon in the gaseous giant planet TYC 8998-760-1 b at a distance ...
