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.

2 days ago, the Sun emitted a strong solar flare, which might reach Earth today. Last August, @mabrentjens, radio astronomer at ASTRON, explained what effects these solar flares can have on our technologies.

The upgrade of our #LOFAR telescope is featured in @SKAO's Contact magazine! We are currently working on a major upgrade towards LOFAR2.0, which will give us more data, more accuracy, and simultaneous usage of our LBA and HBA antennas.

Over 70 students from all over the world participated in the 9th European Radio Interferometry School (#ERIS2022) - hosted by @jivevlbi and ASTRON & funded by the #H2020 @ORP_Astro - in Dwingeloo (the Netherlands) on 19-23 September 2022 @RadioNet_EU

Gigantic radio sources up to ten million light years in size discovered in the universe using the LOFAR radio telescope. Read more about this exciting result on the website of @HambObs
