The standard model to produce non-thermal particles is the particle acceleration at shocks. However, the photon spectra in high-energy objects, such as blazars, frequently show very hard feature, which seems inconsistent with the standard shock acceleration theory. The alternative model is the particle acceleration by turbulence. Here, we propose the particle acceleration by large scale...

Astrophysical shocks are known to accelerate particles to high relativistic velocities. This process requires the particles to repeatedly cross the shock, a process that can only occur if the particle is reflected by the local magnetic field. Such particles are observed on Earth as cosmic rays.
This phenomenon has been studied in considerable detail for high-Mach shocks, such as the shocks...

The conventional transport theory for core-collapse supernovae misses one key property of elementary particles, the chirality. We show that the chiral transport phenomena due to the chirality of elementary particles that have been neglected so far can reverse the turbulent cascade direction from direct to inverse cascade, which would impact the hydrodynamic evolution of the supernova core...

High energy astrophysics, cosmic rays/Multi-messenger
Oral presentation in parallel session
Presently the explosions of supernovae are considered as sources of Galactic cosmic rays up to energies of $\sim 10^{17}$ eV. But, the experimental data obtained with Pamela, Fermi, AMS-02, spectrometers require the existence of nearby sources of cosmic rays at the distances less than one kpc. These sources could explain the growth of the ratio of galactic positrons to electrons with an...

Oral presentation in parallel session
Neutron stars have many interesting physical features, such as the high-density,
strong magnetic field, cooling, rapidly rotation, and glitches.
Among them, the strong magnetic field has been a focus of constant attention.
In particular, the behavior of high density matter in strong magnetic fields is
an important issue in studies about EOS and it has been discussed in many...
