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.

Congratulations to our colleague Harish Vedantham who has been awarded a @NWONieuws #Vidi grant for his project e-MAPS! 🥳 With e-MAPS Harish will use @LOFAR to answer the question: what determines the magnetic field of an exoplanet?💫

Congratulations @AstroJoeC on winning the Louise Webster prize with the discovery of Apep, a unique binary star system with the hottest stars in the Universe.

What does the start of construction of @SKAO mean for the Netherlands? Michiel van Haarlem: "we are due to take on work in the following areas: software for the calibration of data and the creation of deep sky images, " read the full interview here:

Another impressive result for LOFAR! An international team of astronomers from @UniLeiden & @mediainaf discovered a galaxy that seems to be wagging it's tail, a tail of 2,5 million light years long! 💫
