The best of both worlds: Combining LOFAR and Apertif to derive resolved radio spectral index images
R. Morganti, T. A. Oosterloo, M. Brienza +36
Supermassive black holes at the centres of galaxies can cycle through periods of activity and quiescence. Characterising the duty cycle of active galactic nuclei is crucial for und…
Systematic effects in LOFAR data: A unified calibration strategy
F. de Gasperin, T. J. Dijkema, A. Drabent +17
Context: New generation low-frequency telescopes are exploring a new parameter space in terms of depth and resolution. The data taken with these interferometers, for example with t…
Low-Frequency Radio Absorption in Cassiopeia A
M. Arias, J. Vink, F. de Gasperin +3
Cassiopeia A is one of the best-studied supernova remnants. Its shocked ejecta emits brightly in radio and X-rays. Its unshocked ejecta can be studied through infrared emission, th…
The Association of a J-burst with a Solar Jet
D. E. Morosan, P. T. Gallagher, R. A. Fallows +56
Context. The Sun is an active star that produces large-scale energetic events such as solar flares and coronal mass ejections and numerous smaller-scale events such as solar jets.…
Wide-field LOFAR imaging of the field around the double-double radio galaxy B1834+620: A fresh view on a restarted AGN and doubeltjes
E. Orrú, S. van Velzen, R. F. Pizzo +8
The existence of double-double radio galaxies (DDRGs) is evidence for recurrent jet activity in AGN, as expected from standard accretion models. A detailed study of these rare sour…
The nature of the low-frequency emission of M51: First observations of a nearby galaxy with LOFAR
D. D. Mulcahy, A. Horneffer, R. Beck +25
The grand-design spiral galaxy M51 was observed with the LOFAR High Frequency Antennas (HBA) and imaged in total intensity and polarisation. This observation covered the frequencie…
