Resonant third harmonic generation of super-Gaussian laser beam in a rippled density plasma

open access: yesJournal of Theoretical and Applied Physics, 2018
Resonant third harmonic generation of super-Gaussian laser beam in rippled density plasma is studied. Both the relativistic and ponderomotive nonlinearities are included in the analysis, and the study is done for self-guided laser beam.

Particle Acceleration in Relativistic Outflows [PDF]

open access: yesSpace Science Reviews, 2012
In this review we confront the current theoretical understanding of particle acceleration at relativistic outflows with recent observational results on various source classes thought to involve such outflows, e.g. gamma-ray bursts, active galactic nuclei, and pulsar wind nebulae.

Effect of dust on tilted electrostatic resistive instability in a Hall thruster

open access: yesJournal of Theoretical and Applied Physics, 2018
Effect of negatively charged dust on resistive instability corresponding to the electrostatic wave is investigated in a Hall thruster plasma when this purely azimuthal wave is tilted and strong axial component of wave vector is developed.

Small amplitude dust acoustic solitary wave in magnetized two ion temperature plasma

open access: yesJournal of Taibah University for Science, 2020
The characteristics of obliquely propagating dust acoustic solitary wave in magnetized dusty plasma are analysed by considering the plasma to have electrons, two-temperature ions and massive dust grains with heavy charge.

Particle Acceleration Mechanisms [PDF]

open access: yesInternational Astronomical Union Colloquium, 1994
AbstractHigh-energy particle acceleration is observed to proceed in a diverse variety of astrophysical sites ranging from the terrestrial aurorae to the most distant quasars. Particle acceleration is a fairly common channel for the release of large-scale kinetic, rotational, and magnetic energy.

Particle acceleration in binaries

open access: yesEPJ Web of Conferences, 2017
Cygnus X-3 massive binary system is one of the powerful sources of radio and X-ray emission consisting of an accreting compact object, probably a black hole, with a Wolf-Rayet star companion.

Particle Acceleration and Their Escape into the Heliosphere in Solar Flares with Open Magnetic Field

open access: yesThe Astrophysical Journal, 2023
Energetic particle populations in the solar corona and in the heliosphere appear to have different characteristics even when produced in the same solar flare.

Growth of Rayleigh instability in a Hall thruster channel having dust in exit region

open access: yesAIP Advances, 2019
In a Hall thruster, the axial movement of ions towards the exit of the chamber and the divergence of ion beam sputter the wall and thus the maximum erosion of wall of the exit region takes place.

Mathematical modelling of seed-mediated size-specific growth of spherical silver nanoparticles using Azadirachta indica leaf extract

open access: yesJournal of Taibah University for Science, 2020
Spherical silver nanoparticles of required size were synthesized employing a seed-mediated approach using leaf extract of Azadirachta indica. Reaction pH was used to manipulate the rate of reduction of the precursor salt for achieving a fast rate of ...

Neutral particle acceleration by spatially modulated laser pulses

open access: yesNew Journal of Physics, 2023
The velocity gain of neutral particles (atoms, molecules, etc) from laser acceleration is always small. A possible scheme to obtain a high speed neutral particle beam is multistage acceleration. However, according to previous theoretical and experimental
