Time resolved 3Dinterferometric imaging of a section of a negative leader with LOFAR
Olaf Scholten, Brian Hare, Joe Dwyer +6
We have developed a three dimensional (3D) interferometric beamforming technique for imaging lightning flashes using Very-High Frequency (VHF) radio data recorded from several hund…
Chromatic periodic activity down to 120 MHz in a Fast Radio Burst
Inés Pastor-Marazuela, Liam Connor, Joeri van Leeuwen +34
Fast radio bursts (FRBs) are extragalactic astrophysical transients whose brightness requires emitters that are highly energetic, yet compact enough to produce the short, milliseco…
The initial stage of cloud lightning imaged in high-resolution
O. Scholten, B. M. Hare, J. Dwyer +21
With LOFAR we have been able to image the development of lightning flashes with meter-scale accuracy and unprecedented detail. We discuss the primary steps behind our most recent l…
Radio emission from negative lightning leader steps reveals inner meter-scale structure
B. M. Hare, O. Scholten, J. Dwyer +19
We use the Low Frequency ARray (LOFAR) to probe the dynamics of the stepping process of negatively-charged plasma channels (negative leaders) in a lightning discharge. We observe t…
Reconstructing air shower parameters with LOFAR using event specific GDAS atmospheres
P. Mitra, A. Bonardi, A. Corstanje +15
The limited knowledge of atmospheric parameters like humidity, pressure, temperature, and the index of refraction has been one of the important systematic uncertainties in reconstr…
On the cosmic-ray energy scale of the LOFAR radio telescope
K. Mulrey, S. Buitink, A. Corstanje +14
Cosmic rays are routinely measured at LOFAR, both with a dense array of antennas and with the LOFAR Radboud air shower Array (LORA) which is an array of plastic scintillators. In t…
