Reaching thermal noise at ultra-low radio frequencies: the Toothbrush radio relic downstream of the shock front
F. de Gasperin, G. Brunetti, M. Bruggen +14
Ultra-low frequency observations (<100 MHz) are particularly challenging because they are usually performed in a low signal-to-noise ratio regime due to the high sky temperature an…
LOFAR 58 MHz Legacy Survey of the 3CRR Catalog
J. M. Boxelaar, F. De Gasperin, M. J. Hardcastle +4
The Low Frequency Array (LOFAR) is uniquely able to perform deep, 15" resolutions imaging at frequencies below 100 MHz. Observations in this regime, using the Low Band Antenna (LBA…
Nearby galaxies in the LOFAR Two-metre Sky Survey III. Influence of cosmic-ray transport on the radio-SFR relation
V. Heesen, S. Schulz, M. Brüggen +7
Context. In order to understand galaxy evolution, it is essential to measure star formation rates (SFRs) across Cosmic times. Aims. The use of radio continuum emission as an extinc…
A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE) XX. Star formation in the tidal tail of NGC 4254
A. Boselli, A. Lupi, P. Serra +26
ALMA 12CO(1-0) observations of 42 star-forming regions located outside the disc of the Virgo Cluster galaxy NGC4254 within an HI gas tail produced during the galaxy's interaction w…
Re-energisation of AGN head-tail radio galaxies in the galaxy cluster ZwCl0634.1+47474
G. Lusetti, F. de Gasperin, V. Cuciti +10
Low-frequency radio observations show an increasing number of radio galaxies located in galaxy clusters that display peculiar morphologies and spectral profiles. This is the result…
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…
