Scalable and robust wide-field facet calibration with LOFAR's longest baselines
J. M. G. H. J. de Jong, L. Veefkind, R. J. van Weeren +8
Recent work has successfully achieved sub-arcsecond wide-field imaging with high-band observations from the Low Frequency Array (LOFAR). However, the scalability of this work remai…
Unlocking ultra-deep wide-field imaging with sidereal visibility averaging
J. M. G. H. J. de Jong, R. J. van Weeren, T. J. Dijkema +3
Producing ultra-deep high-angular-resolution images with current and next-generation radio interferometers introduces significant computational challenges. In particular, the imagi…
Into the depths: Unveiling ELAIS-N1 with LOFAR's deepest sub-arcsecond wide-field images
J. M. G. H. J. de Jong, R. J. van Weeren, F. Sweijen +11
We present the deepest wide-field 115-166 MHz image at sub-arcsecond resolution spanning an area of 2.5 by 2.5 degrees centred at the ELAIS-N1 deep field. To achieve this, we impro…
Deep sub-arcsecond widefield imaging of the Lockman Hole field at 144 MHz
F. Sweijen, R. J. van Weeren, H. J. A. Röttgering +11
High quality low-frequency radio surveys have the promise of advancing our understanding of many important topics in astrophysics, including the life cycle of active galactic nucle…
Sub-arcsecond imaging with the International LOFAR Telescope I. Foundational calibration strategy and pipeline
L. K. Morabito, N. J. Jackson, S. Mooney +71
[abridged] The International LOFAR Telescope is an interferometer with stations spread across Europe. With baselines of up to ~2,000 km, LOFAR has the unique capability of achievin…
