New calibration technique circumvents Earth’s ionosphere
An international team of researchers has developed a new calibration technique to circumvent disturbances of Earth’s ionosphere.
ASTRON has turned 75!
75 years ago today, SRZM (Stichting Radiostraling van Zon en Melkweg/Netherlands Foundation for Radio Astronomy) was founded. This organization would later become ASTRON.
ASTRON launches database of female experts
Today marks International Women’s Day. This year’s theme is ‘Inspire Inclusion’.
LOFAR ERIC: Distributed Research Infrastructure for European Astronomical Research Launched
LOFAR ERIC (European Research Infrastructure Consortium) has been officially launched at its first Council meeting today. The world-leading LOFAR (LOw Frequency ARray) Distributed Research Infrastructure has already revolutionised low-frequency radio astronomy research, resulting in an avalanche of scientific publications in the past decade. LOFAR ERIC is now a single legal entity across the European Union. The LOFAR ERIC statutory seat is in Dwingeloo, the Netherlands, hosted by NWO-I/ASTRON (Netherlands Institute for Radio Astronomy; the original designer of LOFAR).

Graphs have only been around since Leonhard Euler solved the crossing problem of the Seven Bridges of Königsberg in 1736. Their exploration and use have served various areas of interest, from pure mathematics to applied engineering. We have explored the world of graph theory to investigate a puzzling aspect of radio pulsars: the connection between their magnetosphere configuration and energy relative to our line-of-sights towards them. We developed a framework to perform graph-related analysis tasks efficiently, along with plotting methods to unveil complex multi-dimensional data in a unified picture. We present this work in a recent article by Vohl, van Leeuwen, and Maan (2024, A&A)Open Dag: 6 oktober/Open Day: October 6th
