We study the interaction of upstream ultralow frequency (ULF) waves with collisionless shocks by analyzing the outputs of 11 2D local hybrid simulation runs. Our simulated shocks have Alfvénic Mach numbers between 4.29 and 7.42 and their θBN angles are 15° , 30° , 45° , and 50° . The ULF wave foreshocks develop upstream of all of them. The wavelength and the amplitude of the upstream waves exhibit a complex dependence on the shock's MA and θBN . The wavelength positively correlates with both…

Parametric Study of Magnetosheath Jets in 2D Local Hybrid Simulations

We perform 2D local hybrid simulations of collisionless shocks in order to study the properties of simulated magnetosheath jets as a function of shock properties, namely their Alfvénic Mach number (M

Ultra-low frequency (ULF) waves in the Pc3 range, with periods between 10–45 s, are routinely observed in Earth’s dayside magnetosphere. They are thought to originate in the foreshock, which extends



Waves and turbulence in high Mach number nearly parallel collisionless shocks

We have performed a number of one-dimensional hybrid simulations (massless electrons, macroions) of almost parallel collisionless shocks (angle between the upstream magnetic field and shock normal of

Low‐frequency wave characteristics in the upstream and downstream regime of the terrestrial bow shock

[1] Collisionless shocks in space are accompanied by the low-frequency waves of the magnetic field both upstream and downstream of the shock. However, characteristics of these waves in the plasma


Two-dimensional hybrid simulations are performed to investigate the interaction of Alfvén waves with a perpendicular shock self-consistently. The perpendicular shock is formed by reflecting the

Interaction of Hydromagnetic Waves with Hydromagnetic Shocks

The problem of the interaction of small‐amplitude plane hydromagnetic waves with plane, oblique hydromagnetic shocks is treated. When the perturbations of the flow field on either side of the shock

Dispersion analysis of low‐frequency waves through the terrestrial bow shock

[1] We present dispersion relations of low-frequency waves observed upstream and downstream of the Earth's bow shock analyzing Cluster magnetometer measurements along an outbound orbit covering four

Global hybrid simulations: Foreshock waves and cavitons under radial interplanetary magnetic field geometry

[1] We use global hybrid (kinetic ions and fluid electrons) simulations to study the solar wind interaction with the magnetosphere for a radial (θvB = 0) interplanetary magnetic field (IMF) geometry.

Critical angles of incidence for transmission of magnetohydrodynamic waves across shock surfaces

When an MHD wave impinges on a fast shock from its upstream side, in general it may excite six diverging waves on the downstream side when the angle of incidence, the angle between the normal

Instabilities of low frequency, parallel propagating electromagnetic waves in the Earth's foreshock region

We compute the electromagnetic dispersion relation for right- and left-hand circularly polarized low frequency waves propagating parallel and antiparallel to the upstream interplanetary magnetic
