Descripción

The LOw Frequency ARray (LOFAR) is a low frequency (<200 MHz) radio telescope based in The Netherlands with stations all over Europe. I will first discuss the impact of LOFAR as a pathfinder for the Square Kilometer Array (SKA), and highlight the unique the aspects that will ensure LOFAR remains a cutting-edge instrument well into the SKA era. I will also explain what data products the Surveys team has made available to the astronomy community, comprising 85% of the Northern sky to 6’' resolution at 150 MHz. Finally, I will discuss the contribution of LOFAR to my own research field, supernova remnants (SNRs). At low radio frequencies, the synchrotron emission of SNRs is modulated by the presence of foreground ionized material, which allows us to probe the cold, dense gas surrounding, interacting with, or internal to the SNR shock.
