Thermal Radiation from GRB Jets
Akira Mizuta, Shigehiro Nagataki, Junichi Aoi
In this study, the light curves and spectrum of the photospheric thermal radiation from ultrarelativistic gamma-ray burst (GRB) jets are calculated using 2D relativistic hydrodynam…
Origins of Short Gamma-Ray Bursts Deduced from Offsets to Their Host Galaxies Revisited
Xiao-Hong Cui, Junichi Aoi, Shigehiro Nagataki +1
The spatial distribution of short Gamma-ray bursts (GRBs) in their host galaxies provide us an opportunity to investigate their origins. Based on the currently observed distributio…
Propagation of ultrahigh energy nuclei in clusters of galaxies: resulting composition and secondary emissions
K. Kotera, D. Allard, K. Murase +4
We study the survival of ultrahigh energy nuclei injected in clusters of galaxies, as well as their secondary neutrino and photon emissions, using a complete numerical propagation…
Can we probe the Lorentz factor of gamma-ray bursts from GeV-TeV spectra integrated over internal shocks?
Junichi Aoi, Kohta Murase, Keitaro Takahashi +2
We revisit the high-energy spectral cutoff originating from the electron-positron pair creation in the prompt phase of gamma-ray bursts (GRBs) with numerical and analytical calcula…
The effect of energy amplification variance on the shock-acceleration
Junichi Aoi, Kohta Murase, Shigehiro Nagataki
The shock-acceleration theory predicts a power-law energy spectrum in the test particle approximation, and there are two ways to calculate a power-law index, Peacock's approximatio…
