  1. — Many galaxies are seen to be undergoing a range of activity associated with an active nucleus. Whilst much effort goes into understanding the mechanisms involved, very few authors have considered how such AGNs might form.

  2. — Our group has for many years being studying the formation of galaxies based on the collapse and fragmentation of self-gravitating gas dynamics (e.g. Williams, 1997).

  3. — However, to produce jets (which we are using as a tracer of AGN activity) requires additional physics. Other work (e.g. Matsumoto et al., 1996) has shown that magnetic fields are important in the production of jets from accretion discs.

  4. — Hence we have produced a fully self-gravitating, magnetohydrodynamic code with the aim of studying the formation of an AGN starting from the initial collapse of a primordial overdensity.
