Reconstructing cosmology with LOFAR

The LOFAR Two-metre Sky Survey (LoTSS) opens a new observational window for modern cosmology. In this presentation I will describe how the second data release of LoTSS allows us to reconstruct several aspects of today's standard model of cosmology. The rich multi-frequency data of the LoTSS deep fields play a crucial role to break several parameter degeneracies...
