COBE limits on explosive structure formation scenariosThe Compton y-distortion that would result from an epoch of explosions at moderate redshifts is estimated and compared to recent measurements of the CBR spectrum made by the COBE satellite. The temperature anisotropy on large angular scales is estimated, and it is found that in general the limits on the overall spectral distortion are more constraining than those on the temperature anisotropy. It is found that most of the y-distortion is produced during the early, noncosmological phase of bubble evolution. An expression is obtained for the y-distortion including the effects of Compton cooling. The implications of the findings are discussed.
