Periodic Fast Radio Burst found bare, unobscured by strong binary wind

By connecting two of the biggest radio telescopes in the world, astronomers have discovered that a simple binary wind cannot cause the puzzling periodicity of a Fast Radio Burst after all.

Most detailed-ever images of galaxies revealed using LOFAR

After almost a decade of work, an international team of astronomers has published the most detailed images yet seen of galaxies beyond our own, revealing their inner workings in unprecedented detail.

Vidi grant awarded to astronomer Harish Vedantham

Astronomer Harish Vedantham of the Netherlands Institute for Radio Astronomy (ASTRON) and the University of Groningen has been awarded a ‘VIDI' grant of 800,000 Euros from the Netherlands Organization for Scientific Research (NWO).

The galaxy with a wagging tail

One of the most massive galaxies at the centre of the Abell 1775 cluster has a 2.5 million light-year long tail – twice as long as previously thought – that appears to be “wagging”.

Famous fast radio burst FRB20180916B just barely lets itself be captured

Two international teams of astronomers (with significant Dutch involvement) have published two scientific papers with new information about the famous fast radio burst FRB20180916B.

Ultra-sensitive radio images reveal thousands of star-forming galaxies in early Universe

An international team of astronomers has published the most sensitive images of the Universe ever taken at low radio frequencies, using the International Low Frequency Array (LOFAR).

A starry sky made of more than 25,000 supermassive black holes

An international team of astronomers has produced the largest and sharpest map of the sky at ultra-low radio frequencies, using the Low Frequency Array (LOFAR) radio telescope. The map published in the journal Astronomy & Astrophysics reveals more than 25,000 active supermassive black holes in distant galaxies.

SKAO is born - Launch of international Observatory signals new era for radio astronomy

The SKA Observatory, a new intergovernmental organisation dedicated to radio astronomy, was launched today following the first meeting of the Observatory’s Council.

ASTRON reveals life cycle of supermassive black hole

For the first time LOFAR and WSRT-Apertif have been used together to measure the life cycle of supermassive black holes emitting radio waves.

Cosmic flashes come in all different sizes

On May 24, four European telescopes took part in the global effort to understand mysterious cosmic flashes. The telescopes captured flashes of radio waves from an extreme, magnetised star in our galaxy.

Data release from the first year of the Apertif imaging surveys

The Apertif imaging team has released science data from the first year of science operations of WSRT-Apertif as the Apertif Data Release 1 (DR1). Now the entire astronomical community can access the data collected by Apertif in its first year of observing, which started on 1 July 2019.

First direct detection of a brown dwarf with a radio telescope

Astronomers at ASTRON  have discovered a brown dwarf with LOFAR. The discovery of the object dubbed Elegast, opens up a new path that uses radio telescopes to discover faint objects that are close-cousins of Jupiter-like exoplanets.
