An Ignored Assumption of CDM Cosmology and An Old Question: Do We Live On The "Center" of The Universe?
Ding-fang Zeng, Yi-hong Gao
We point out that CDM cosmology has an ignored assumption. That is, the component of the universe moves synchronously with ordinary matters on Hubble scales. If cosmological…
Super-horizon Perturbations and CMBA
Ding-fang Zeng, Yi-hong Gao
We provided a gedanken experiment and argued that since observers inside a given Hubble volume could not detect the super horizon perturbation modes as real perturbations, these mo…
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…
