| :Explosions During Galaxy Formation | | When density fluctuations collapse gravitationally out of the expanding cosmological background universe to form galaxies, the secondary energy release which results can affect their subsequent evolution profoundly. Focused upon here are the effects of one form of such energy release - explosions, such as might result from the supernovae which end the lives of the first generation of massive stars to form inside protogalaxies. As an idealized model which serves to illustrate and quantify the importance of these effects, the effect of explosions on the quasi-spherical objects which form in the plane of a cosmological pancake, as a result of gravitational instability and fragmentation of the pancake, are studied by numerical gas dynamical simulation in 3D utilizing a new, anisotropic version of Smoothed Particle Hydrodynamics developed by Paul Shapiro and Hugo Martel of the Galaxy Formation and the Intergalactic Medium Research Group, Adaptive SPH (ASPH), coupled to a P3M gravity solver. |
