Low-Frequency Array

(LOFAR)
(low frequency radio telescope)

The Low-Frequency Array (LOFAR) is a Radio Telescope operating at 10-240MHz, aimed at detecting the Hydrogen (H) 21cm Line Redshifted (z) from the Epoch of Reionization (EOR) (much like Murchison Widefield Array (MWA)). It was completed in 2012 in Europe and has an effective collecting area of 300,000 square meters. It is operated by the Netherlands Institute for Radio Astronomy.

It consists of separate stations, each station with a number of simple, stationary antenna, the majority in a single 2 × 3 km tract in the Netherlands (the LOFAR-Core) and the rest further afield in the Netherlands and other European countries, providing a 1000km baseline. Imaging is done using Aperture Synthesis/Phased Array techniques.
