This paper discusses a semi-numerical method of investigating
the enrichment of the intergalactic medium by galactic winds. We
find that most galaxies at z ～ > 3 should be driving winds, and that (i...

There is no single mechanism by which fast particles are accelerated in astrophysical environments, and it is now recognized that the data require a rich variety of different mechanisms operating unde...

We model the latest HST WFPC3/IR observations of > 100 galaxies at redshifts z=7-8 in terms of a hierarchical galaxy formation model with starburst activity. Our model provides a distribution of UV lu...
