I am a postdoc fellow at the Netherlands Institute for Radio Astronomy (ASTRON) and currently doing research on the Epoch of Reionization, as a member of the LOFAR-EoR key science project, and on physics of the Galactic and extragalactic radio emission (foregrounds in the EoR experiments).

Briefly, the Epoch of Reionization (EoR) demarcates the era in the history of the Universe when neutral gas in the intergalactic medium was almost entirely ionized by the radiation of the first sources. This epoch holds the key to structure formation and evolution, but also represents a missing piece of the puzzle in our current knowledge of the Universe. Currently, this is changing with the completion of a new generation of radio telescopes, which are capable of directly probing the EoR by detecting the radiation emitted by the neutral hydrogen from this epoch.

The Low Frequency Array (LOFAR) is the first telescope of this kind, and will use an array of simple radio antennas (dipoles) to detect the radio signals from the Universe. Beside the cosmological aim of the LOFAR project to probe the EoR, the observations with the LOFAR radio telescope will provide probably the deepest images of the low frequency radio sky. These images can be used for cutting-edge scientific studies, e.g. to explore the properties of the Galactic emission, magnetic fields, extragalactic sources, etc..
