Chandra observations of bent-double radio sources in clusters and groups
Abstract
Bent, double-lobed radio sources often attain their C-shaped morphologies from the ram pressure resulting from the relative motion of the host galaxy and the dense, hot gas associated with a cluster or group of galaxies. Wide-angle tail (WAT) radio sources fall in this class. These types of radio sources are most often hosted by bright elliptical or cD galaxies located in cluster or group environments. Therefore, they can be used as signposts for these types of environments at a large range of redshifts. We will present Chandra observations of a high-redshift (z=0.96) cluster of galaxies associated with a bent-double radio source selected from the VLA FIRST survey. In addition, we will present Chandra observations of low-redshift bent-double radio sources found in very poor environments that are likely "fossil groups" of galaxies.
