Solving the Inverse Problem with Inhomogeneous Universes
Chul-Moon Yoo, Tomohiro Kai, Ken-ichi Nakao
We construct the Lemaître-Tolman-Bondi (LTB) dust universe whose distance-redshift relation is equivalent to that in the concordance cold dark matter (CDM) cosmological mode…
Magnification Probability Distribution Functions of Standard Candles in a Clumpy Universe
Chul-Moon Yoo, Hideki Ishihara, Ken-ichi Nakao +1
Lensing effects on light rays from point light sources, such like Type Ia supernovae, are simulated in a clumpy universe model. In our universe model, it is assumed that all matter…
Primordial Neutrinos, Cosmological Perturbations in Interacting Dark-Energy Model: CMB and LSS
Kiyotomo Ichiki, Yong-Yeon Keum
We present cosmological perturbation theory in neutrinos probe interacting dark-energy models, and calculate cosmic microwave background anisotropies and matter power spectrum. In…
Quantum Fluctuations in the Inflationary Universe
Sang Pyo Kim
The recent three-year WMAP data selects large-field models with certain power-law potentials and small-field models for all power-law potentials as consistent inflation models. We…
