ON THE POSSIBILITY OF COHERENTLY STIMULATED RECOMBINATION AND COSMOLOGICAL STRUCTURE GENERATION - COSMOLOGICAL CONSEQUENCES

Given a specific physical mechanism for instabilities during cosmologi cal recombination discussed in an earlier paper, we examine the nonlin ear growth of density structures to form fractal-like structural patte rns out to the horizon scale at that epoch (similar to 200 Mpc today), A model for such fractal patterns is presented. Such effects could ex plain observed large-scale structure patterns and the formation of obj ects at high z, while keeping microwave background anisotropies at the observed minimal levels. We also discuss possible microwave backgroun d implications of such a transition and note a potentially observable spectral signature at lambda similar to 0.18 mm as well as a weak line near the peak in the microwave background.
