Scientific paper

The Low Frequency Array (LOFAR) is a new generation of electronic radio telescope based on aperture array technology. The telescope is being developed by ASTRON, and currently being rolled out across the Netherlands and other countries in Europe. I present the current status of the project, and its relation to high resolution instruments such as the European VLBI Network (EVN) and the Very Long Baseline Array (VLBA). In particular, I present recent VLBI results at 327 MHz associated with: (i) a shallow survey based on VLBA archive data and (ii) a deep, wide-field Global VLBI survey centred on two in-beam calibrators, B0218+357 and J0226+3421. The results suggest that there will be no shortage of relatively bright primary calibrators that remain unresolved by LOFAR even on the longest European baselines. The sky density of fainter in-beam calibrators should also be more than adequate to permit the generation of high fidelity images over a large fraction of the sky, especially in the high-band observing band (120-240 MHz). Extending LOFAR via international stations to baseline lengths of several thousand kilometres is certainly practical and should significantly enhance the scientific output and capabilities of the array.
