TL;DR: In dit artikel zullen the authors LOFAR beschrijven: van de astronomische mogelijkheden met de nieuwe telescoop tot aan een nadere technische beshrijving of het instrument.

TL;DR: The International LOFAR Telescope (ILT) as mentioned in this paper is a new-generation radio interferometer constructed in the north of the Netherlands and across europe, which covers the largely unexplored low frequency range from 10-240 MHz and provides a number of unique observing capabilities.

TL;DR: The LOFAR Two-metre Sky Survey (LoTSS) as mentioned in this paper is a deep 120-168 MHz imaging survey that will eventually cover the entire northern sky, where each of the 3170 pointings will be observed for 8 h, which, at most declinations, is sufficient to produce ~5? resolution images with a sensitivity of ~100?Jy/beam and accomplish the main scientific aims of the survey, which are to explore the formation and evolution of massive black holes, galaxies, clusters of galaxies and large-scale structure.

TL;DR: In this article, the authors derived the magnetic field strength and power spectrum of the Coma cluster magnetic field from the Faraday rotation measure (RM) images with numerical simulations of magnetic field.

TL;DR: The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168 MHz survey of the entire northern sky for which observations are now 20% complete as discussed by the authors.
