Superbubble breakout and galactic winds from<br />
disk galaxies<br />
Arpita Roy; Biman B. Nath; Prateek Sharma; Y. Shchekinov<br />
We study the evolution <strong>of</strong> superbubbles driven by large star clusters<br />
in disk galaxies using Kompaneets approximation and numerical<br />
simulations. We investigate the effect <strong>of</strong> radiative losses on the<br />
dynamics <strong>of</strong> superbubbles, in particular the conditions required for<br />
superbubbles to break through the disk material to throw the inner<br />
hot gas into the halo with sufficient speed so as to create a galactic<br />
outow. We nd that our calculations and simulations may explain<br />
the observed threshold star formation surface density required to<br />
create superwinds from disk galaxies.<br />
