Telescopes

ASTRON is responsible for the operations of the Westerbork Synthesis Radio Telescope (WSRT) and the Low Frequency Array (LOFAR).

Astronomy

The astronomical research at ASTRON is closely aligned with the strengths of our facilities LOFAR and WSRT-APERTIF.

Diversity & Sustainability

ASTRON is committed to achieving a fair, welcoming, and sustainable work environment for all.

Beschermingszones


Met onze radiotelescopen nemen wij de meest zwakke signalen uit het heelal waar. Daardoor zijn zij kwetsbaar voor elektromagnetische storing. Met het tijdig treffen van de juiste maatregelen kan storing worden voorkomen.

Wireless Data Lab


Draadloze techniek lijkt vanzelfsprekend, maar de ontwikkeling ervan gaat niet vanzelf. Daarom hebben we bij ASTRON een proeftuin ingericht; het Wireless Data Lab.

PhD defence Emma van der Wateren

On June 10th, Emma van der Wateren successfully defended her thesis titled "Illuminating the properties of radio pulsars and their binary companions through pulsar timing" at the Radboud University in Nijmegen. Emma worked under the supervision of Gemma Janssen and Cees Bassa as co-promotors and Gijs Nelemans as promotor on this joint PhD project between Nijmegen and ASTRON.

In her thesis, Emma used timing of radio pulsars with LOFAR, WSRT and other radio telescopes to study a wide variety of physical processes of pulsars and their binary companions, finding that pulsars discovered with LOFAR are generally older than pulsars discovered at higher frequencies, identifying a pulsar in a binary with very long orbital period, and assesing the timing stability of "a black widow pulsar binary for the use in experiments to detect gravitational waves.

Since October last year, Emma joined ASTRON as an instrument scientist.
