LOFAR: The LOw-Frequency ARray

M. P. van Haarlem, M. W. Wise, A. W. Gunst +197

LOFAR, the LOw-Frequency ARray, is a new-generation radio interferometer constructed in the north of the Netherlands and across europe. Utilizing a novel phased-array design, LOFAR…

LOFAR tied-array imaging and spectroscopy of solar S bursts

D. E. Morosan, P. T. Gallagher, P. Zucca +50

Context. The Sun is an active source of radio emission that is often associated with energetic phenomena ranging from nanoflares to coronal mass ejections (CMEs). At low radio freq…

LOFAR imaging of the solar corona during the 2015 March 20 solar eclipse

A. M. Ryan, P. T. Gallagher, E. P. Carley +12

The solar corona is a highly-structured plasma which can reach temperatures of more than ~2 MK. At low frequencies (decimetric and metric wavelengths), scattering and refraction of…

LBCS: the LOFAR Long-Baseline Calibrator Survey

N. Jackson, A. Tagore, A. Deller +76

(abridged). We outline LBCS (the LOFAR Long-Baseline Calibrator Survey), whose aim is to identify sources suitable for calibrating the highest-resolution observations made with the…

LOFAR tied-array imaging of Type III solar radio bursts

D. E. Morosan, P. T. Gallagher, P. Zucca +82

The Sun is an active source of radio emission which is often associated with energetic phenomena such as solar flares and coronal mass ejections (CMEs). At low radio frequencies (<…

LOFAR observations of the quiet solar corona

C. Vocks, G. Mann, F. Breitling +9

The quiet solar corona emits meter-wave thermal bremsstrahlung. Coronal radio emission can only propagate above that radius, , where the local plasma frequency eqals the obse…

Shock location and CME 3D reconstruction of a solar type II radio burst with LOFAR

P. Zucca, D. E. Morosan, A. P. Rouillard +62

Type II radio bursts are evidence of shocks in the solar atmosphere and inner heliosphere that emit radio waves ranging from sub-meter to kilometer lengths. These shocks may be ass…
