We review how supersonic turbulence can both prevent and promote the collapse of molecular clouds into stars. First we show that decaying turbulence cannot significantly delay coll…
Giant and `double-double' radio galaxies: Implications for the evolution of powerful radio sources and the IGM
A. P. Schoenmakers, A. G. de Bruyn, H. J. A. Röttgering +3
Giant radio sources form the linear size extreme of the extra-galactic radio source population. Using the WENSS survey, we have selected a complete sample of these sources. We have…
