About me

I am a postdoctoral  fellow working at the Dutch Institute for Radio Astronomy (ASTRON)  and the Kapteyn Astronomical Institute of the Rjiksuniversiteit Groningen. My  research focuses on the Epoch of Reionization (see below), especially from the observational aspects side. I am a core member of the LOFAR-EoR key science project. My other interests are the physics of the early Universe, relativity in higher-order spaces and supercomputing.

(Note: Both Labropoulos and Lampropoulos are valid spellings of my name, but I prefer the former one. Panos is short for Panagiotis.)
Detecting the Epoch of Reionization with LOFAR
One of the most exciting applications of LOFAR (the LOw Frequency ARray) will be the search for redshifted 21 cm line emission from the Epoch of Reionisation (EoR). It is currently believed that the Dark Ages, the period after recombination when the Universe turned neutral, lasted until around the Universe was 400,000 years old. During the EoR, objects started to form in the early universe and they were energetic enough to ionize neutral hydrogen.  The most prominent method to unravel the string leading to this epoch is the 21-cm line of neutral hydrogen, the most abundant element in the Universe. Due to the expansion of the Universe, this line is redshifted to the low regime of the radio spectrum with wavelengths of the order of a few meters. The sensitivity required to achieve this scientific goal, essentially translates  into accumulating large amounts of data. Furthermore, the data have to be corrected for instrumental and atmospheric distortions to an unprecedented level.
