‘Physics of Radio Galaxies’
‘Radio Galaxies as beacons to early, massive galaxy formation’
Central Engine: accreting SMBH (>108 Mo)
Jets: collimated outflow
Origin of FRI/FRII dicotomy?
Lobes: ‘jet waste products’ [outflow or backlow]
Hot spots: jet terminal shock
Collimated flow from 1pc to 1 Mpc
Terminal jet shocks: double structure 60kpc from core
PAPER 120 – 180 MHz
α= -0.5 to -1.2
