Mirror modes: Nonmaxwellian distributions
M. Gedalin, Yu. E. Lyubarsky, M. Balikhin +2
We perform direct analysis of mirror mode instabilities from the general dielectric tensor for several model distributions, in the longwavelength limit. The growth rate at the inst…
Efficient electron heating in relativistic shocks and gamma ray burst afterglow
M. Gedalin, M. A. Balikhin, D. Eichler
Electrons in shocks are efficiently energized due to the cross-shock potential, which develops because of differential deflection of electrons and ions by the magnetic field in the…
Turbulent viscosity variability in self-propelled body wake model
K. Dubrovin, M. Gedalin, E. Golbraikh +1
We study the influence of turbulent viscosity variability on the properties of self-propelled body wake model. In addition to the already known integrals of motion obtained with co…
The dynamic quasiperpendicular shock: Cluster discoveries
V. Krasnoselskikh, M. Balikhin, S. N. Walker +9
The physics of collisionless shocks is a very broad topic which has been studied for more than five decades. However, there are a number of important issues which remain unresolved…
Coherent Emission from Magnetars
D. Eichler, M. Gedalin, Y. Lyubarsky
It is proposed that magnetospheric currents above the surfaces of magnetars radiate coherent emission in analogy to pulsars. Scaling the magnetospheric parameters suggests that the…
Optical Solitary Waves in the Higher Order Nonlinear Schrodinger Equation
M. Gedalin, T. C. Scott, Y. B. Band
We study solitary wave solutions of the higher order nonlinear Schrodinger equation for the propagation of short light pulses in an optical fiber. Using a scaling transformation we…
Kinetic description of avalanching systems
M. Gedalin, M. Balikhin, D. Coca +2
Avalanching systems are treated analytically using the renormalization group (in the self-organized-criticality regime) or mean-field approximation, respectively. The latter descri…
New mechanism of pulsar radio emission
M. Gedalin, E. Gruman, D. B. Melrose
It is shown that pulsar radio emission can be generated effectively through a streaming motion in the polar-cap regions of a pulsar magnetosphere causing nonresonant growth of wave…
Pick-up ion dynamics at the structured quasi-perpendicular shock
D. Zilbersher, M. Gedalin
We study the pickup ion dynamics and mechanism of multiple reflection and acceleration at the structured quasi-perpendicular supercritical shock. The motion of the pickup ions in t…
Whistler precursor and intrinsic variability of quasi-perpendicular shocks
G. Granit, M. Gedalin
The structure of whistler precursor in a quasi-perpendicular shock is studied within two-fluid approach in one-dimensional case. The complete set of equations is reduced to the KdV…
The determination of shock ramp width using the noncoplanar magnetic field component
J. A. Newbury, C. T. Russell, M. Gedalin
We determine a simple expression for the ramp width of a collisionless fast shock, based upon the relationship between the noncoplanar and main magnetic field components. By compar…
Direct Measurements of Synchrotron-Emitting Electrons at Near-Sun Shocks
I. C. Jebaraj, O. V. Agapitov, M. Gedalin +22
In this study, we present the first-ever direct measurements of synchrotron-emitting heliospheric traveling shocks, intercepted by the Parker Solar Probe (PSP) during its close enc…
