The German Long Wavelength Consortium (GLOW) was formed in 2006 by German universities and research institutes to use the radio spectral window at meter wavelengths for astrophysical research. This new window to the universe offers unprecedented insights into many astrophysical processes, which cannot be observed elsewhere. The evolution of galaxy clusters, magnetic fields in the intergalactic medium, the nature and evolution of pulsars, and solar outbursts are examples of such processes.
High-resolution imaging at very low frequencies requires baselines of many hundreds of kilometres length, which has been made possible with the construction of several stations for the International LOFAR Telescope (ILT). GLOW provides a substantial part of such baselines through their six LOFAR stations listed below. These stations were build between 2007 and 2014 (coordinates can be found here).
Frequencies: Each LOFAR station has 96 dual polarisation antennas for the frequency range 10-80 MHz and 96 tiles of 16 dual-polarisation antennas, for the range 110-240 MHz.
