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...Tags: sdss, wenss, nvss, uss, alpha, spectral index, gb6

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...Tags: mnras, arxiv, polarization, agn, nvss, sdss, vla, atca, galaxy, unresolved

Automated Source Finding - SAD
Having looked at the C-field 13 Jul 2010 Release with Duchamp and encountering a few issues I thought it would be prudent to run a similar analysis with the AIPS implemenation of SAD. In the Stokes I image, some 489 sources were found down to a detection threshold of 1K (as with Duchamp a numbe...Tags: galfacts, cfield, igalfa, sources, source finding, nvss, gb6, sad, aips

- 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).

A Deep 150 MHz GMRT Survey in Eridanus
We present results of a 150 MHz survey of a field centered on Epsilon Eridani, undertaken with the Giant Metrewave Radio Telescope (GMRT). The survey covers an area with a diameter of 2 deg, has a spatial resolution of 30" and a noise level of 3.1 mJy at the pointing centre. These observations pr...Tags: gmrt, 150, nvss, vlss, 7c, radio, eps eri
