Impacts of the image alignment over frequency for VLBI Global Observing System
Ming H. Xu, Tuomas Savolainen, James M. Anderson +4
The VLBI Global Observing System, which is the next generation of geodetic VLBI and is called VGOS, observes simultaneously at four frequency bands in the range 3.0--10.7 GHz (expe…
The impacts of source structure on geodetic parameters demonstrated by the radio source 3C371
Ming H. Xu, Robert Heinkelmann, James M. Anderson +4
Closure quantities measured by very long baseline interferometry (VLBI) observations are independent of instrumental and propagation instabilities and antenna gain factors, but are…
The source structure of 0642+449 detected from the CONT14 observations
Ming H. Xu, Robert Heinkelmann, James M. Anderson +3
The CONT14 campaign with state-of-the-art VLBI data has observed the source 0642+449 with about one thousand observables each day during a continuous observing period of fifteen da…
Imaging Jupiter's radiation belts down to 127 MHz with LOFAR
J. N. Girard, P. Zarka, C. Tasse +71
Context. Observing Jupiter's synchrotron emission from the Earth remains today the sole method to scrutinize the distribution and dynamical behavior of the ultra energetic electron…
Initial LOFAR observations of Epoch of Reionization windows: II. Diffuse polarized emission in the ELAIS-N1 field
V. Jelic, A. G. de Bruyn, M. Mevius +106
This study aims to characterise the polarized foreground emission in the ELAIS-N1 field and to address its possible implications for the extraction of the cosmological 21-cm signal…
Detecting cosmic rays with the LOFAR radio telescope
P. Schellart, A. Nelles, S. Buitink +102
The low frequency array (LOFAR), is the first radio telescope designed with the capability to measure radio emission from cosmic-ray induced air showers in parallel with interferom…
The LOFAR Magnetism Key Science Project
James Anderson, Rainer Beck, Michael Bell +12
Measuring radio waves at low frequencies offers a new window to study cosmic magnetism, and LOFAR is the ideal radio telescope to open this window widely. The LOFAR Magnetism Key S…
LOFAR: Recent imaging results & future prospects
George Heald, Michael R. Bell, Andreas Horneffer +27
The Low Frequency Array (LOFAR) is under construction in the Netherlands and in several surrounding European countries. In this contribution, we describe the layout and design of t…
