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.

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.

Two ERC Starting Grants awarded to (space) weather research projects with the LOFAR radio telescope

The European Research Council (ERC) has awarded two of its prestigious Starting Grants to ASTRON scientists for research projects using the LOFAR radio telescope. One project will use LOFAR to create detailed images of lightning on Earth, the other aims to detect space weather events and magnetic fields around exoplanets.

Jessica Dempsey appointed director of ASTRON

The board of the Dutch Research Council’s institute organisation has appointed Prof. Dr. Jessica Dempsey as director of ASTRON, the Netherlands Institute for Radio Astronomy.

Volcanic ‘activity’ in black holes blows monumental bubbles spanning hundreds of thousands of light years

An international team of researchers, which included astronomers from the Netherlands Institutes for Radio Astronomy (ASTRON) and Space Research (SRON) as well as Leiden University, observed the full extent of the evolution of hot gas produced by an active black hole for the first time.

Colloquium: The Canadian Hydrogen Observatory and Radio-transient Detector (CHORD)

In recent years, radio observatories have been reshaped by rapid developments in the digital and telecommunications sectors. Technological advancements have allowed for faster surveys, larger fields-of-view, and a multiplicity of commensal studies, with corresponding scientific returns.

Building off the experience and knowledge developed on the highly successful Canadian Hydrogen Intensity Mapping Experiment (CHIME), the Canadian Hydrogen Observatory and Radio-transient Detector (CHORD) is a large-N, small-D, ultra-wideband radio array under construction in Canada. Using a dense-packed “core” array of 512x 6m dishes located immediately next to CHIME, CHORD will observe over a 5:1 band spanning 300-1500MHz. Two smaller “outrigger” stations, located at VLBI distances, will supplement the core for high-precision astrometry.

CHORD will commensally produce and process a wide range of data products feeding a variety of studies, from cosmological 21cm intensity mapping to Fast Radio Burst (FRB) discovery & localization. In this talk, I will discuss the background, motivation, and design of the array, followed by current progress and prototyping efforts. Full funding for CHORD was recently secured, with construction taking place over the coming 3 years and first light scheduled for 2025.
