Abstract
LOFAR for the first time offers the possibility to image the radio sky at wavelengths of a few metres with a resolution in the arcsec range or better. This is made possible by international stations that provide baselines of several hundred km and turn LOFAR into an e-VLBI array.
In this talk I give an overview of first high-resolution observations using the International LOFAR Telescope and discuss the particular challenges of long-baseline LOFAR observations.
