What is LOFAR?

LOFAR (Low Frequency Array) is a new radio telescope under construction by ASTRON in the Netherlands operating between 30 and 240 MHz. In this largely unexplored frequency range, LOFAR will be the dominant telescope over the next decade. The improvement in sensitivity by a factor of 20 and resolution by a factor of 100 compared with present-day telescopes will open a new window on the Universe.

LOFAR leads the way for a new generation of radio telescopes that consist of a multitude of small and cheap antenna fields. As there will be no moving parts, the costs for mechanical maintenance are low. The astronomical radio waves are sampled digitally, the signal is transmitted over large baselines to a high-performance computing facility where the radio images are synthesized in real time. The central computer (a Blue Gene/P, one of the fastest in the world) is already in place at the University of Groningen. This innovative design based on digital beam-forming will allow to point the telescope simultaneously at several positions on sky (8 simultaneous beam are planned). In principle, the whole visible radio sky can be monitored continuously.


The European LOFAR

The capabilities of LOFAR can be increased enormously by extending it to a European level. The extension will provide baselines of several thousands kilometers and hence improve the resolution by another order of magnitude. Presently, United Kingdom, France, Germany, Sweden, Poland and Ireland are actively pursuing a participation in the LOFAR European network (see picture above for an artist rendering; Spektrum der Wissenschaft/Emde-Grafik). The construction of LOFAR remote stations in Germany is ongoing (Effelsberg; Tautenburg; Potsdam; Jülich; Hamburg).


LOFAR at MPA

The Max-Planck-Institute of Astrophysics (MPA) in Garching is one of the German Institutions which participate in the European LOFAR Project and plan to build up a LOFAR remote station. The LOFAR Project at the MPA aims at the construction of an antenna field in the vicinity of Garching. This will operate within the distributed LOFAR radio telescope.
