Figure 3. Possible post-population-III creation of stars. Relativistic proton jets from the supermassive black hole in the galactic centre are thermalized and form globular clusters of Population II stars, the material of which after supernova explosions ends up as Population I stars in the galactic disc, and then eventually gets drawn back into the central black hole in the galactic centre, from which it again may be emitted as pristine hydrogen in the form of relativistic jets, etc
