Very Long Baseline Interferometry with the SKA Observatory

J. F. Radcliffe, J. Yang, Z. Paragi +129

Very Long Baseline Interferometry (VLBI) is a fundamental technique that combines signals from telescopes separated by thousands of kilometres to obtain some of the highest-resolut…

Polarisation and Faraday rotation measure imaging at metre wavelengths with sub-arcsecond resolution: a foundational calibration strategy

R. J. van Weeren, J. M. G. H. J. de Jong, X. K Le Saux +12

Low-frequency radio polarimetric observations provide a powerful probe of magnetic fields in astrophysical sources and the intervening medium, as well as magnetospheric emission fr…

Probing the environments of FRI and FRII radio galaxies in LoTSS DR2 with galaxy clusters

Tong Pan, Yuming Fu, H. J. A. Rottgering +7

The origin of the Fanaroff--Riley Class I/II (FRI/FRII) morphological dichotomy remains uncertain. We investigate whether cluster-scale environment contributes to this distinction…

The LOFAR sub-arcsecond view of the high-redshift radio relic in PSZ2G091.83+26.11

G. Di Gennaro, R. Timmerman, M. Hoeft +14

Enhanced inverse Compton (IC) losses at high redshift steepen diffuse radio spectra in galaxy clusters, making low-frequency (~100 MHz) observations favorable. However, low-frequen…

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…

Characterization of the decametre sky at subarcminute resolution

C. Groeneveld, R. J. van Weeren, E. Osinga +11

The largely unexplored decameter radio band (10-30 MHz) provides a unique window for studying a range of astronomical topics, such as auroral emission from exoplanets, inefficient…

Abell 0399-Abell 0401 radio bridge spectral index: the first multifrequency detection

G. V. Pignataro, A. Bonafede, G. Bernardi +12

Recent low-frequency radio observations at 140 MHz discovered a 3 Mpc-long bridge of diffuse emission connecting the galaxy clusters Abell 0399 and Abell 0401. We present follow-up…

1-arcsecond imaging of ELAIS-N1 field at 144MHz using the LoTSS survey with international LOFAR telescope

Haoyang Ye, Frits Sweijen, Reinout van Weeren +10

We present the first wide area (2.5 x 2.5 deg^2) LOFAR High Band Antenna image at a resolution of 1.2'' x 2'' with a median noise of approximately 80 microJy per beam. It was made…

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…
