The Destruction of Cosmological Minihalos by Primordial Supernovae

Understand

We present numerical simulations of primordial supernovae in cosmological minihalos at $z \sim$ 20.

• We consider Type II supernovae, hypernovae, and pair instability supernovae (PISN) in halos from 6.9 $\times$ 10$^5$ - 1.2 $\times$ 10$^7$ $\Ms$, those in which Population III stars are expected to form via H$_2$ cooling.
• The supernovae evolve along two evolutionary paths according to whether they explode in \ion{H}{2} regions or neutral halos.
• Those in \ion{H}{2} regions first expand adiabatically and then radiate strongly upon collision with baryons ejected from the halo during its photoevaporation by the progenitor.
