Electron and Photon Energy Deposition in Universe
Toru Kanzaki, Masahiro Kawasaki
We consider energy deposition of high energy electrons and photons in universe. We carry out detailed calculations of fractions of the initial energy of the injected electron or ph…
Solving the cosmic lithium problems with primordial late-decaying particles
Daniel Cumberbatch, Kazuhide Ichikawa, Masahiro Kawasaki +3
We investigate the modifications to predictions for the abundances of light elements from standard Big-Bang nucleosynthesis when exotic late-decaying particles with lifetimes excee…
Stability of a cosmological model with dynamical cancellation of vacuum energy
A. D. Dolgov, M. Kawasaki
The stability of cosmological solutions in the recently suggested specific mechanism of dynamical compensation of vacuum energy is studied. It is found that the solutions in the or…
Double Inflation in Supergravity and the Boomerang Observations
Toshiyuki Kanazawa, Masahiro Kawasaki, Naoshi Sugiyama +1
One of the biggest mystery of the recent observation of cosmic microwave background anisotropies by the boomerang team is insignificance of the second acoustic peak in the angular…
