Brane Quintessence
Kei-ichi Maeda
We propose a new quintessence scenario in the brane cosmology, assuming that a quintessence field is confined in our 3-dimensional brane world. With a potential $V(Q)= μ^{α+4}…
Brane preheating
Shinji Tsujikawa, Kei-ichi Maeda, Shuntaro Mizuno
We study brane-world preheating in massive chaotic inflationary scenario where scalar fields are confined on the 3-brane. Assuming that quadratic contribution in energy densities d…
Explosive Nucleosynthesis in Aspherical Hypernova Explosions and Late Time Spectra of SN1998bw
K. Maeda, T. Nakamura, K. Nomoto +3
Aspherical explosion models for the hypernova (hyper-energetic supernova) SN 1998bw are presented. Nucleosynthesis in aspherical explosions is examined with a two-dimensional hydro…
Gravitational waves from a spinning particle scattered by a relativistic star: Axial mode case
Kazuhiro Tominaga, Motoyuki Saijo, Kei-ichi Maeda
We study gravitational waves from a spinning test particle scattered by a relativistic star using a perturbation method. The present analysis is restricted to axial modes. By calcu…
Origin of scaling structure and non-gaussian velocity distribution in self-gravitating ring model
Yasuhide Sota, Osamu Iguchi, Masahiro Morikawa +2
Fractal structures and non-Gaussian velocity distributions are characteristic properties commonly observed in virialized self-gravitating systems such as galaxies or interstellar m…
Dilaton-gravity on the brane
Kei-ichi Maeda, David Wands
We derive the four-dimensional field equations for the induced metric and scalar field on the world-volume of a 3-brane in a five-dimensional bulk with Einstein gravity plus a self…
