The Large-Scale Distribution of Radio Sources
We have used a sample of 263 Parkes half-Jansky at-spectrum radio sources to measure the spatial correlation function of radio galaxies and radio-loud quasars on scales up to 1000h ?1 Mpc. We do not detect any clustering in the sample. If any undetected clustering is described by a power-law spatial correlation function ((r) = (r=r 0) ?1:8), we can rule out clustering with scales r 0 50 h ?1 Mp...
متن کاملOn the interaction of FR-II radio sources with the intracluster medium
The effect of the expansion of powerful FR-II radio sources into a cluster environment is discussed. The analysis considers both the thermal and temporal evolution of the ICM which has passed through the bow shock of the radio source and the effect of this swept-up gas on the dynamics of the radio source itself. The final state of the swept-up ICM is critically dependent on the thermal conducti...
متن کاملThe Origins of X-ray Emission from the Hot Spots of Fr Ii Radio Sources
We use new and archival Chandra data to investigate the X-ray emission from a large sample of compact hot spots of FR II radio galaxies and quasars from the 3C catalog. We find that only the most luminous hot spots tend to be in good agreement with the predictions of a synchrotron self-Compton model with equipartition magnetic fields. At low hot spot luminosities inverse Compton predictions are...
متن کاملLarge-scale Radio Structure in the Universe: Giant Radio Galaxies
Giant radio galaxies (GRGs), with linear sizes larger than 1 Mpc (H0 = 50 km s Mpc), represent the biggest single objects in the Universe. GRGs are rare among the entire population of radio galaxies (RGs) and their physical evolution is not well understood though for many years they have been of special interest for several reasons. The lobes of radio sources can compress cold gas clumps and tr...
متن کاملDynamical and chemical effects of FR II radio sources on the intra - cluster medium
We investigate the effects of intermittent strong jets from an Active Galactic Nuclei (AGN) of a massive galaxy in the core of a cool core galaxy cluster, on the dynamics and metal distribution of the intra-cluster medium (ICM). We use a simple model for the metal distribution within the host galaxy which includes metal injection via star formation. We carry out 2D axisymmetric hydrodynamic sim...
