The LOFAR telescope is used to conduct wide and deep surveys with unprecedented resolution and sensitivity at low radio frequencies. This advances our understanding of the formation and evolution of massive black holes and clusters of galaxies.

LOFAR surveys

Astronomers at ASTRON are using the surveys to conduct research on high redshift radio sources, active galactic nuclei, star formation, gravitational lensing, galactic radio emission, cosmology, magnetic fields, transients and recombination lines. The team is also active involved in pipeline development, calibration, image processing techniques and more. Once complete, the LOFAR surveys will detect and characterise approximately 15,000,000 radio sources  about 90%  of which are expected to be new discoveries.

See special issue of Astronomy & Astrophysics with science results from the first data release.

Daily Image of the Week: Two ERC Starting Grants awarded to (space) weather research projects with the LOFAR radio telescope

Deadline for applications for our summer research proramme is 31 January 2022!

For all information see or the AAS website:

🎉We are proud! Two ERC Starting Grands awarded to ASTRON employees Brian Hare & Harish Vedantham!

One project will use @LOFAR to create detailed images of lightning, the other aims to detect space weather events & magnetic fields around exoplanets:

Ons #WDL biedt het mkb uit Noord-NL de optie onze kennis en middelen in te zetten voor uitdagingen op het gebied van radiogolven, zonder zelf de apparatuur en faciliteiten aan te schaffen.
