Hard X-ray and Gamma-ray Emission Induced by Ultra-High Energy Protons in Cluster Accretion Shocks and their Detectability
Susumu Inoue, Felix A. Aharonian, Naoshi Sugiyama
Protons can be plausibly accelerated to - eV in strong accretion shocks surrounding massive clusters of galaxies. Such protons efficiently produce very high…
Gravitational Radiation from Coalescing Supermassive Black Hole Binaries in a Hierarchical Galaxy Formation Model
Motohiro Enoki, Kaiki T. Inoue, Masahiro Nagashima +1
We investigate the expected gravitational wave emission from coalescing supermassive black hole (SMBH) binaries resulting from mergers of their host galaxies. We employ a semi-anal…
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…
CMB radiation power spectrum in CDM open universes up to 2nd order perturbations
Jose L. Sanz, Enrique Martinez-Gonzalez, Laura Cayon +2
A second--order perturbation theory approach is developed to calculate temperature anisotropies in the cosmic microwave background. Results are given for open universes and fluctua…
