Effects of chemical and energy feedback in the formation of galaxies

We study the eects of Supernova feed- back in the evolution of galaxies by using a newly developed model for chemical en- richment and energy feedback within the code GADGET-2. Our model suceeds in producing a self-regulated cycle for star formation and in triggering strong out ows of enriched mater...

We study the eects of Supernova feed- back in the evolution of galaxies by using a newly developed model for chemical en- richment and energy feedback within the code GADGET-2. Our model suceeds in producing a self-regulated cycle for star formation and in triggering strong out ows of enriched material which contaminate the outer regions of galaxies. This result could in principle explain the presence of metals observed in the intergalactic medium. One of the main advantages of this model over early approaches is that it has been devel- oped without introducing scale or resolution dependent paramaters which might depend on the virial mass of galaxies, becoming an important tool to study cosmological structure formation. © 2006: Instituto de Astronomía, UNAM.
