Radio galaxy evolution: what you can learn from a brief encounter
NEW ASTRON REV 46:2-7 (2002) 75-87
Abstract:
We describe the pitfalls encountered in deducing from classical double radio source observables (luminosity, spectral index, redshift and linear size) the essential nature of how these objects evolve. We discuss the key role played by hotspots in governing the energy distribution of the lobes they feed, and subsequent spectral evolution. We present images obtained using the new 74 MHz receivers on the VLA and discuss constraints which these enforce on models of the backflow and ages in classical doubles.

3-D general relativistic MHD simulations of generating jets
ASTR SOC P 250 (2002) 22-26
Abstract:
We have performed the first full 3-D GRMHD simulation of a Schwarzschild black hole with a freely falling corona. The preliminary simulation results show that the accretion disc is falling with the corona and that the proper pressure increases near the black hole, as in the previous axisymmetric simulations. We expect that in this case an instability around the black hole will occur as a result of the steep pressure gradient and the twisted magnetic fields. We plan to investigate how the instability affects jet formation.3C Radio Sources as They've Never Been Seen Before
