RODRIGUEZ-GONZALEZ, A.; ESQUIVEL, A.; RAGA, A. C.  y  COLIN, P. Mass and metal ejection efficiency in disk galaxies driven by young stellar clusters of nuclear starburst. Rev. mex. astron. astrofis [online]. 2011, vol.47, n.1, pp. 113-125. ISSN 0185-1101.

We present results from models of galactic winds driven by energy injected by nuclear starbursts. The total energy of the starburst is provided by young central stellar clusters and parts of the galactic interstellar médium are pushed out as part of the galactic wind (in some cases the galactic wind contains an important part of the metáis produced in the new generation of stars). We have performed adiabatic and radiative 3D N-Body/Smooth Particle Hydrodynamics simulations of galactic winds using the GADGET-2 code. The numerical models cover a wide range of starburst and galactic gas masses The concentrated central starburst regions are an efficient engine for producing the mass and metal loss in galaxies, and also for driving the metal redistribution in galaxies.
