Abstract : A giant radio galaxy (GRG) is an extreme type of active galaxy that has radio jets of a size larger than 0.7 Mpc. Most of the known GRGs are of FRII type whose jets remain laminar and relativistic throughout their whole journey in a single phase of activity. How some radio galaxies evolve to such a large scale is still an unsolved mystery. The size of GRGs depends on mostly three factors, i.e. IGM density, jet power, and age of the source. It was believed that GRGs are born in a sparse environment. However, some GRGs were also found in clusters of galaxies. To determine the jet power and age of the largest GRGs it is crucial to analyze multi-frequency radio maps of proper uv-coverage, angular resolution, and sensitivity. In this poster, we present the radio properties of a 2 Mpc size GRG from our sample.
