Show moreIn this thesis we push the boundaries of high-resolution imaging at radio frequencies between 100 and 200 MHz. Using the International LOFAR Telescope that spans across Europe we achieve sub-arcsecond angular resolution. We demonstrate mapping of the full field of view of the telescope at its native resolution and use the resulting images to study active galactic nuclei in the Lockman Hole field. Show less
