On Acceleration of Highest-Energy Cosmic Rays in a Novel Scenario of Magnetar Transients
Jiro Shimoda, Tomoki Wada
Transient phenomena in magnetars have been considered as possible acceleration sites of ultrahigh-energy cosmic-rays (CRs), whose energy reaches ~200 EeV, such as the Amaterasu par…
Large-scale Magnetic Field Model of GRB Afterglow Polarization: Effects of Field Anisotropy, Off-axis Viewing Angle, and Ordered Field
Asuka Kuwata, Kenji Toma, Sara Tomita +1
The afterglows of gamma-ray bursts are non-thermal electron synchrotron emissions from relativistic shocks. The origin of strong magnetic field in the emission region remains elusi…
Fermi and eROSITA Bubbles as Persistent Structures of the Milky Way
Jiro Shimoda, Katsuaki Asano
The Fermi and eROSITA bubbles, large diffuse structures in our Galaxy, can be the by-products of the steady star formation activity. To simultaneously explain the star formation hi…
The Dzhanibekov Effect as a Possible Source of Magnetar Activity
Tomoki Wada, Jiro Shimoda
Magnetars, which are neutron stars with strong magnetic fields, exhibit occasional bursting activities. The shape of a magnetar is not perfectly spherical due to the Lorentz force…
