  • Typical NVSS Field

    A typical NVSS image. The NRAO VLA Sky Survey (NVSS) is a 1.4 GHz continuum survey covering the entire sky north of -40 deg declination (Condon, J. J., Cotton, W. D., Greisen, E. W., Yin, Q. F., Perley, R. A., Taylor, G. B., & Broderick, J. J. 1998, AJ, 115, 1693).

  • 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...

  • Radio sources with ultra-high polarisation

    A sample of 129 unresolved radio sources with ultra-high linear polarisation (>30 per cent) has been selected from the NVSS (NRAO VLA Sky Survey). Such high average linear polarisation is unusual in extragalactic sources. Higher resolution ATCA (Australia Telescope Compact Array) and VLA (Very...
