Statistical Analysis of High-frequency Whistler Waves at Earth's Bow Shock: Further Support for Stochastic Shock Drift Acceleration
Takanobu Amano, Miki Masuda, Mitsuo Oka +3
We statistically investigate high-frequency whistler waves (with frequencies higher than % of the local elect ron cyclotron frequency) at Earth's bow shock using Magnetos…
Enhanced Magnetic Field Amplification by Ion-Beam Weibel Instability in Weakly Magnetized Astrophysical Shocks
Taiki Jikei, Takanobu Amano, Yosuke Matsumoto
We examine the evolution of ion-beam Weibel instability at strong collisionless shocks in weakly magnetized media. We find that a finite background magnetic field substantially aff…
Linearly-polarized Coherent Emission from Relativistic Magnetized Ion-electron Shocks
Masanori Iwamoto, Yosuke Matsumoto, Takanobu Amano +2
Fast radio bursts (FRBs) are millisecond transient astrophysical phenomena and bright at radio frequencies. The emission mechanism, however, remains unsolved yet. One scenario is a…
Electron-Ion Temperature Ratio in Astrophysical Shocks
John C. Raymond, Parviz Ghavamian, Artem Bohdan +9
Collisionless shock waves in supernova remnants and the solar wind heat electrons less effectively than they heat ions, as is predicted by kinetic simulations. However, the values…
Nonthermal Electron Acceleration at Collisionless Quasi-perpendicular Shocks
T. Amano, Y. Matsumoto, A. Bohdan +6
Shock waves propagating in collisionless heliospheric and astrophysical plasmas have been studied extensively over the decades. One prime motivation is to understand the nonthermal…
Theory of Electron Injection at Oblique Shock of Finite Thickness
Takanobu Amano, Masahiro Hoshino
A theory of electron injection into diffusive shock acceleration (DSA) for the generation of cosmic-ray electrons at collisionless shocks is presented. We consider a recently propo…
