| dc.description | Using weakly nonlinear conditional PDF for the density field around an overdense region we find that the expected density contrast around a peak is always smaller while its rms fluctuation larger than in the linear case. We apply these results to the spherical model of collapse as developed by Hoffman & Shaham (1985) and find that in the case of open Universe the effect of weakly nonlinear interactions is to decrease the scale from which a peak gathers mass and the mass itself as well as to steepen the final profile of the virialized protoobject. | |
