2011/10/20
We cross match the NVSS and FIRST surveys with three large photometric catalogues of luminous red galaxies (LRGs) to define radio-loud samples. These have median redshifts 0.35, 0.55 and 0.68 and, by ...
Deep imaging of Fanaroff-Riley Class I radio galaxies with lobes
galaxies: jets – radio continuum:general – magnetic fi elds – polarization
2011/10/8
We present deep, high-resolution imaging of the nearby Fanaroff-Riley Class I (FR I) radio galaxies NGC 193, B2 0206+35, B2 0755+37 and M 84 at frequencies of 4.9 and 1.4 GHz using new and archival mu...

Using Chandra imaging spectroscopy and Very Large Array (VLA) L-band radio maps, we have identified radio sources at P_{1.4GHz} >=5x10^{23} W Hz^{-1} and X-ray point sources (XPSs) at L_{0.3-8keV}>=5x...
The Multiwavelength Study of Two Unique Radio Galaxies
Galaxies clusters individual (Hercules A, 3 C310)
2009/5/19
We present the usage of multi-frequency and multi-band
radio, VLA, observations as well as X-ray observations in order to study
the environment around two powerful radio galaxies, namely Hercules A
