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.

We are very proud of @mabrentjens who has won @UniLeiden's Teacher of the Year 2022 award!

Today, construction on the #SKA radio telescope officially started. Together with @CGI_Global, S[&]T, and @TriOpSys we are already developing important software components for processing the vast amounts of data the SKA telescope will produce.

Today was the official start of the construction of the @SKAO's #SKA radio telescope in Australia and South Africa. Together with #TOPIC, we are already working on the development of the central signal processor for the SKA Low frequency telescope.

Daily image of the week: LDV gets busy
The LTA hosts about 60 PB of data, making it the largest astronomical data collection to date and an invaluable resource for science. The LDV aims to make these data available to the community.
