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: The logarithmic slope of the mass function for substructure beyond the local Universe is determined to be , with an average mass fraction of per cent, by combining data on both of these recently discovered galaxies, consistent with the predictions from cold dark matter simulations at the 95 per cent confidence level.
