Radio astronomers join global standards body seeking to address satellite interference

The Committee on Radio Astronomy Frequencies (CRAF) has been admitted as an I-member of the International Special Committee on Radio Interference (CISPR), the international body that sets standards to prevent electronic devices from interfering with each other.

Astronomers pinpoint the source of the brightest one-off fast radio burst ever

An international team of astronomers has localized one of the brightest non-repeating fast radio bursts (FRBs) ever observed to a nearby galaxy.

In Memoriam: Albert-Jan Boonstra

It is with deep sadness we share the news that our longtime colleague, Albert-Jan Boonstra, has passed away on Friday, August 1.

Astronomers uncover white dwarf system emitting bright radio pulses with strange rhythm

Researchers identify a mystifying Long-Period Transient with 100% polarized radio emission, suggesting new type of cosmic radio source. A team of astronomers at ASTRON, the Netherlands Institute for Radio Astronomy, has discovered a mysterious new cosmic radio source that challenges current theories about how dead stars can produce such powerful emissions. Using the LOFAR (Low Frequency Array) radio telescope, the team picked up the unusual signal as part of a study led by astronomer Sanne Bloot. This research was published today in the scientific journal Astronomy & Astrophysics.

Exoplanet Sparks Stellar Fireworks

Astronomers have witnessed a planet causing storms to erupt on its parent star, a discovery that could reshape our understanding of how planets and stars interact and evolve together. These findings are published today in the scientific journal Nature.

New ‘mini halo’ discovery deepens our understanding of how the early Universe was formed

Astronomers have uncovered a vast cloud of energetic particles – a ‘mini halo’ – surrounding one of the most distant galaxy clusters ever observed, using the LOFAR radio telescope, marking a major step forward in understanding the hidden forces that shape the cosmos.

8th LOFAR Data School

We are happy to announce that the 8th LOFAR Data School (LDS2026) will take place at ASTRON, the Netherlands Institute for Radio Astronomy (Dwingeloo, The Netherlands) from 16 to 23 September 2026. RATIONALE The goal of the school is to assist the participants in the generation and analysis of LOFAR science ready data. The school will cover the […]

Cursus: Toegepaste RF-techniek

De cursus Toegepaste RF-techniek bestaat uit een theoriegedeelte (75%) en hands-on sessies in ons eigen lab (25%).
Deelnemers aan deze cursus dienen een hbo werk- en denkniveau te hebben. De deelnemer kent de basisbegrippen van elektronica. Parate kennis van wiskundige concepten is niet vereist, maar komt wel aan de orde bij de transmissielijntheorie. In de cursus wordt ook complexe rekenwijze toegepast.
