Description
Over the past five years, LOFAR’s Low Band Antenna (LBA) system has opened a new observational window in the electromagnetic spectrum, enabling imaging at unprecedented resolution and sensitivity. Until now the Dutch array has mainly been used for science. We present results from observations using both the Dutch and full International LOFAR Telescope where we imaged bright 3C sources at arcsecond resolution. This marks the first time such imaging has been achieved under sub-optimal ionospheric conditions. With these normal and high-resolution, ultra-low-frequency maps, we investigate The AGN lobe kinematics and energetics, and test the validity of classical plasma aging models at low frequencies. These results lay the groundwork for more extensive long-baseline LBA observations in the near future, especially as LOFAR2.0 comes online
