Spherical Collapse Model And Dark Energy(II)
Ding-fang Zeng, Yi-hong Gao
This is a second paper of a series of two. In this paper, we directly correct the problem pointed out in the first paper of this series, dark energy does not cluster on the scale o…
Spherical Collapse Model And Dark Energy(I)
Ding-fang Zeng, Yi-hong Gao
In existing literatures about the top-hat spherical collapse model of galaxy clusters formation in cosmology containing dark energies, dark energies are usually assumed not to clus…
Spherical Collapse Model
Ding-fang Zeng, Yi-hong Gao
We studied the spherical collapse model in the flat CDM cosmology and provided exact and analytical formulaes for the calculation of the two important parameters in the applicat…
Primordial Power Spectrum's Calculation and the Upper Bound on the Number of E-foldings of Inflation
Ding-fang Zeng, Yi-hong Gao
In numerical calculations of the primordial power spectrum of perturbations produced during inflation, for very little wavenumber s, to implement the initial conditions required…
