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…
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…
Matching LOFAR sources across radio bands
Lukas Böhme, Dominik J. Schwarz, Francesco de Gasperin +2
Aims. With the recent preliminary release of the LOFAR LBA Sky Survey (LoLSS), the first wide-area, ultra-low frequency observations from LOFAR were published. Our aim is to combin…
Radio source-component association for the LOFAR Two-metre Sky Survey with region-based convolutional neural networks
Rafaël I. J. Mostert, Kenneth J. Duncan, Lara Alegre +5
Radio loud active galactic nuclei (RLAGNs) are often morphologically complex objects that can consist of multiple, spatially separated, components. Astronomers often rely on visual…
The LOFAR LBA Sky Survey I. survey description and preliminary data release
F. de Gasperin, W. L. Williams, P. Best +38
LOFAR is the only radio telescope that is presently capable of high-sensitivity, high-resolution (<1 mJy/b and <15") observations at ultra-low frequencies (<100 MHz). To utilise th…
The LOFAR Two Meter Sky Survey: Deep Fields, I -- Direction-dependent calibration and imaging
C. Tasse, T. Shimwell, M. J. Hardcastle +29
The Low Frequency Array (LOFAR) is an ideal instrument to conduct deep extragalactic surveys. It has a large field of view and is sensitive to large scale and compact emission. It…
