Complex shock structure in the western hot-spot of Pictor A

Saxton, C.J; Sutherland, Ralph S; Bicknell, Geoffrey V; Blanchet, G.F; Wagner, S.J


We have carried out simulations of supersonic light jets in order to model the features observed in optical and radio images of the western hot-spot in the radio galaxy Pictor A. We have considered jets with density ratios η =10[superscript −2] − 10[superscript −4], and Mach numbers ranging between 5 and 50. From each simulation, we have generated raytraced maps of radio surface brightness at a variety of jet inclinations, in order to study the appearance of time-dependent luminous structures...[Show more]
