Proton Acceleration with Relativistic Electromagnetic Shock. [PDF]

Adv Sci (Weinh)
New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

Non-thermal radio supernova remnants of exiled Wolf-Rayet stars [PDF]

, 2021
A signification fraction of Galactic massive stars ((>= 8 M-circle dot) are ejected from their parent cluster and supersonically sail away through the interstellar medium (ISM). The winds of these fast-moving stars blow asymmetric bubbles thus creating a

Mixing of materials in magnetised core-collapse supernova remnants [PDF]

, 2023
Core-collapse supernova remnants are structures of the interstellar medium (ISM) left behind the explosive death of most massive stars (smaller or equal to 40 Mo).

Wind nebulae and supernova remnants of very massive stars [PDF]

, 2020
A very small fraction of (runaway) massive stars have masses exceeding 60−70M⊙ and are predicted to evolve as luminous blue variable and Wolf–Rayet stars before ending their lives as core-collapse supernovae.

Magnetic Reconnection Detonation in Supernova Remnants [PDF]

, 2018
Expansion of supernova remnants (SNRs) is a key process that refreshes the interstellar medium (ISM) in which a new generation of stars is born. The dynamics and radiative properties of the SNR expansion front not only reflect the physical environment of

Supernova remnants in nearby galaxies [PDF]

, 2020
Supernova remnants (SNRs) are the aftermath of stellar explosions, which inject large amounts of energy into the interstellar medium (ISM), carving out new structures and transferring kinetic energy to the ISM.

Resurrection of Nonthermal Emissions from Type Ib/c Supernova Remnants [PDF]

, 2022
Supernova remnants (SNRs) are important objects in investigating the links among supernova (SN) explosion mechanism(s), progenitor stars, and cosmic-ray acceleration.

MHD Simulation of Supernova Remnants [PDF]

, 2017
We present some Magnetohydrodynamic (MHD) simulations for supernova remnants (SNRs), which hints the thicknesses of SNRs’ shells are likely related to the density and density distribution of surrounding interstellar medium (ISM).

Cosmic-ray acceleration and escape from post-adiabatic supernova remnants [PDF]

, 2020
Context. Supernova remnants are known to accelerate cosmic rays on account of their nonthermal emission of radio waves, X-rays, and gamma rays. Although there are many models for the acceleration of cosmic rays in supernova remnants, the escape of cosmic

Properties of shocked dust grains in supernova remnants [PDF]

, 2022
Shockwaves driven by supernovae both destroy dust and reprocess the surviving grains, greatly affecting the resulting dust properties of the interstellar medium (ISM).
