On the Prompt Signals of Gamma Ray Bursts
Pisin Chen, Toshi Tajima, Yoshi Takahashi
We introduce a new model of gamma ray burst (GRB) that explains its observed prompt signals, namely, its primary quasi-thermal spectrum and high energy tail. This mechanism can be…
The Jem-Euso Mission
Yoshiyuki Takahashi, the JEM-EUSO Collaboration
JEM-EUSO is a space science mission to explore extreme energies and physics of the Universe. Its instrument will watch the dark-side of the earth and will detect UV photons emitted…
JEM-EUSO Science Objectives
Gustavo Medina-Tanco, K. Asano, D. Cline +10
JEM-EUSO, on board of the Japanese Exploration Module of the International Space Station, is being proposed as the first space observatory devoted to UHECR. Its privileged position…
Stability of primordial black holes
Yoshiyuki Takahashi
Vacuum polarization in a strong field, such as Hawking radiation from black holes, is constrained by the directional metric of strong field vectors. Relative localization of the qu…
Plasma Wakefield Acceleration for Ultrahigh Energy Cosmic Rays
Pisin Chen, Toshiki Tajima, Yoshiyuki Takahashi
A cosmic acceleration mechanism is introduced which is based on the wakefields excited by the Alfven shocks in a relativistically flowing plasma, where the energy gain per distance…
Extreme Energy Cosmic Rays (EECR) Observation Capabilities of an "Airwatch from Space'' Mission
C. N. De Marzo
The longitudinal development and other characteristics of the EECR induced atmospheric showers can be studied from space by detecting the fluorescence light induced in the atmosphe…
