Production of ring-like structure in the cocoon of Hercules A

Saxton, C.J; Bicknell, Geoffrey V; Sutherland, Ralph S

Description

The radio lobes of the radio galaxy Hercules A contain intriguing ring-like structures concentric with the jet axis. To investigate the occurrence of such features, we have used hydrodynamic simulations of jets with a range of Mach numbers (from M = 2 to 50) and densities (down to a ratio of 10[superscript −4] relative to the background) to generate ray-traced images simulating synchrotron emission from the time-dependent shock structures. We compare these images with observations of Hercules...[Show more]
