Modelling M87's Shock: Energy in Shocks and Bubbles
sedov simulation piston simulation
The 500 ksec Chandra observation showed that the supermassive black
hole in M87 has driven a classical shock into the surrounding
intracluster gas. We observe a nearly circular ring whose gas
density and gas temperature jumps independently yield the same Mach
number. Now compare superman and winnie the pooh.
