Abstract
The LOFAR-EoR experiment will use the innovative technology and capabilities of the radio telescope LOFAR to study the Epoch of Reionization (EoR). However, feeble cosmological radiation is swamped by the prominent foreground emission of our Galaxy and other extragalactic radio sources. This emission is two to three orders of magnitude stronger than the EoR signal. Without understanding and removing the foreground emission from the data, we will not be able to detect the cosmological radiation and probe the EoR. During my talk I will give an overview of the LOFAR-EoR experiment, its challenges, and present the most recent observational results in particular detection of peculiar structures in poalrization.
