To Understand how galaxies were assembled across the cosmic time remains one of the most outstanding questions in astronomy. The core of this question is how today's Hubble Sequence, namely the differ...
Cosmology today is confronted with several seemingly insoluble puzzles and strange, inexplicable coincidences. But a careful re-examination of the Cosmological principle and the Weyl postulate, founda...
Assessing the Feasibility of Cosmic-Ray Acceleration by Magnetic Turbulence at the Galactic Center
Feasibility Cosmic-Ray Acceleration Magnetic Turbulence the Galactic Center
2012/2/23
The presence of relativistic particles at the center of our galaxy is evidenced by the diffuse TeV emission detected from the inner $\sim$$2^\circ$ of the Galaxy. Although it is not yet entirely clear...
Fermi-LAT Observations of the Diffuse Gamma-Ray Emission: Implications for Cosmic Rays and the Interstellar Medium
Fermi-LAT Observations Diffuse Gamma-Ray Emission Implications Cosmic Rays the Interstellar Medium
2012/2/23
The gamma-ray sky >100 MeV is dominated by the diffuse emissions from interactions of cosmic rays with the interstellar gas and radiation fields of the Milky Way. Observations of these diffuse emissio...
Kneelike structure in the spectrum of the heavy component of cosmic rays observed with KASCADE-Grande

2011/9/25
There is a sort of new lens effect in hyperspherical universe, and it should result in some periodicity in observation. In addition, the cause of supernova and gamma ray burst may be given; the super ...
Three regions of excessive flux of cosmic rays with energies of the order of PeV are found in the experimental data of the EAS MSU array at a confidence level greater than 4\sigma. For two of them, th...
Enhancement of nuclear pasta formation due to multi-nucleus simultaneous collision is presented based on time-dependent density functional calculations with periodic boundary condition. This calculati...
