Subarcsecond international LOFAR radio images of the M82 nucleus at 118 MHz and 154 MHz

E. Varenius, J. E. Conway, I. Martí-Vidal +25

The nuclear starburst in the nearby galaxy M82 provides an excellent laboratory for understanding the physics of star formation. This galaxy has been extensively observed in the pa…

Measuring a Cherenkov ring in the radio emission from air showers at 110-190 MHz with LOFAR

A. Nelles, P. Schellart, S. Buitink +66

Measuring radio emission from air showers offers a novel way to determine properties of the primary cosmic rays such as their mass and energy. Theory predicts that relativistic tim…

Triggering optical AGN: the need for cold gas, and the indirect roles of galaxy environment and interactions

J. Sabater, P. N. Best, T. M. Heckman

We present a study of the prevalence and luminosity of Active Galactic Nuclei (AGN; traced by optical spectra) as a function of both environment and galaxy interactions. For this s…

The LOFAR long baseline snapshot calibrator survey

J. Moldón, A. T. Deller, O. Wucknitz +82

Aims. An efficient means of locating calibrator sources for International LOFAR is developed and used to determine the average density of usable calibrator sources on the sky for s…

The LOFAR Pilot Surveys for Pulsars and Fast Radio Transients

Thijs Coenen, Joeri van Leeuwen, Jason W. T. Hessels +87

We have conducted two pilot surveys for radio pulsars and fast transients with the Low-Frequency Array (LOFAR) around 140 MHz and here report on the first low-frequency fast-radio…

Lunar occultation of the diffuse radio sky: LOFAR measurements between 35 and 80 MHz

H. K. Vedantham, L. V. E. Koopmans, A. G. de Bruyn +91

We present radio observations of the Moon between and MHz to demonstrate a novel technique of interferometrically measuring large-scale diffuse emission extending far bey…
