Shocks, compressible perturbations, and intermittency in the very local interstellar medium: Voyager 1 and 2 observations and numerical modeling
Federico Fraternale, Nikolai V. Pogorelov, Ratan Bera +2
Voyager spacecraft (V1 and V2) provide unique in situ measurements of perturbations propagating beyond the heliopause through the very local interstellar medium (VLISM), including…
Magnetohydrodynamic/Kinetic Modeling of the Interaction between the Solar Wind and the Local Interstellar Medium with He, He, and Pickup H ions and H, He Atoms
Federico Fraternale, Nikolai V. Pogorelov, Ratan K. Bera
The interaction of the solar wind with the local interstellar medium (LISM) spans a wide range of interacting particle populations, energies, and scales. Sophisticated models are r…
The effect of viscosity and resistivity on Rayleigh-Taylor instability induced mixing in magnetized high energy density plasmas
Ratan Kumar Bera, Yang Song, Bhuvana Srinivasan
This work numerically investigates the role of viscosity and resistivity on Rayleigh-Taylor instabilities in magnetized high-energy-density (HED) plasmas for a high Atwood number a…
Excitation and breaking of relativistic electron beam driven longitudinal electron-ion modes in a cold plasma
Ratan Kumar Bera, Arghya Mukherjee, Sudip Sengupta +1
The excitation and breaking of relativistically intense electron-ion modes in a cold plasma is studied using 1D-fluid simulation techniques. To excite the mode, we have used a rela…
Propagation of slow electromagnetic disturbances in plasma
Sharad Kumar Yadav, Ratan Kumar Bera, Deepa Verma +2
Electromagnetic (EM) waves/disturbances are typically the best means to understand and analyze an ionized medium like plasma. However, the propagation of electromagnetic waves with…
Effect of Transverse Beam Size on the Wakefields and Driver Beam Dynamics in Electron Beam Driven Plasma Wakefield Acceleration
Ratan Kumar Bera, Devshree Mandal, Amita Das +1
In this paper, wakefields driven by a relativistic electron beam in a cold homogeneous plasma is studied using 2-D fluid simulation techniques. It has been shown that in the limit…
