The search for radio emission from the exoplanetary systems 55 Cancri, Andromedae, and Boötis using LOFAR beam-formed observations
Jake D. Turner, Philippe Zarka, Jean-Mathias Grießmeier +8
Observing planetary auroral radio emission is the most promising method to detect exoplanetary magnetic fields, the knowledge of which will provide valuable insights into the plane…
Direct radio discovery of a cold brown dwarf
H. K. Vedantham, J. R. Callingham, T. W. Shimwell +9
Magnetospheric processes seen in gas-giants such as aurorae and circularly-polarized cyclotron maser radio emission have been detected from some brown dwarfs. However, previous rad…
Pulsars with NenuFAR: backend and pipelines
L. Bondonneau, J. -M. Grießmeier, G. Theureau +27
NenuFAR (New extension in Nançay upgrading LoFAR) is a new radio telescope developed and built on the site of the Nançay Radio Observatory. It is designed to observe the largely un…
Digitizing analogic spectrograms recorded by the Nançay Decameter Array on 35 mm film rolls from 1970 to 1990
Baptiste Cecconi, Laurent Lamy, Laurent Denis +7
The Nançay Decameter Array (NDA), which has now passed 40 years old, acquires daily observations of Jovian and Solar low frequency radio emissions over a continuous spectrum rangin…
A LOFAR Observation of Ionospheric Scintillation from Two Simultaneous Travelling Ionospheric Disturbances
Richard A. Fallows, Biagio Forte, Ivan Astin +55
This paper presents the results from one of the first observations of ionospheric scintillation taken using the Low-Frequency Array (LOFAR). The observation was of the strong natur…
Cassiopeia A, Cygnus A, Taurus A, and Virgo A at ultra-low radio frequencies
F. de Gasperin, J. Vink, J. P. McKean +49
The four persistent radio sources in the northern sky with the highest flux density at metre wavelengths are Cassiopeia A, Cygnus A, Taurus A, and Virgo A; collectively they are ca…
