WebDec 10, 2013 · In general, dwarf galaxies are expected to dominate metal enrichment at high-redshift for several reasons. As noted above and in the previous subsection, outflows can escape more easily out of the potential wells of dwarfs. Also, at high redshift, massive halos are rare and dwarf halos are much more common. Webdegenerate gas, in physics, a particular configuration, usually reached at high densities, of a gas composed of subatomic particles with half-integral intrinsic angular momentum (spin). Such particles are called fermions, because their microscopic behaviour is regulated by a set of quantum mechanical rules— Fermi-Dirac statistics ( q.v. ).
