  Radiogalaxies in the Sloan Digital Sky Survey: spectral index-environment correlations

  We analyze optical and radio properties of radiogalaxies detected in the Sloan Digital Sky Survey (SDSS). The sample of radio sources are selected from the catalogue of Kimball & Ivezi\'c (2008) with flux densities at 325, 1400 and 4850 MHz, using WENSS, NVSS and GB6 radio surveys and from fl...

In the Stokes I image, some 489 sources were found down to a detection threshold of 1K (as with Duchamp a numbe...
