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…
A spatially resolved radio spectral study of the galaxy M 51
L. Gajović, B. Adebahr, A. Basu +14
Radio continuum emission from galaxies at gigahertz frequencies can be used as an extinction-free tracer of star formation. However, at frequencies of a few hundred megahertz, ther…
Cosmic evolution of FRI and FRII sources out to z=2.5
J. M. G. H. J. de Jong, H. J. A. Röttgering, R. Kondapally +8
Radio-loud active galactic nuclei (RLAGN) play an important role in the evolution of galaxies through the effects on their environment. The two major morphological classes are core…
A deep study of A399-401: An application for wide-field facet calibration
J. M. G. H. J. de Jong, R. J. van Weeren, A. Botteon +6
We examine the particle acceleration mechanism in the Mpc-scale bridge between Abell 399 and Abell 401 and assess in particular if the synchrotron emission originates from first-or…
