Excitation of plasmons in two-dimensional electron gas with defects by microwaves: Wake-field method
plasmons two-dimensional electron gas microwaves Wake-field method
font style='font-size:12px;'>
2011/8/17
Abstract: We develop an analytical method to find plasmons generated by microwaves in a two-dimensional electron gas with defects. The excitations are expressed in terms of the wake field of a charged...
Gravitationally Induced Density Wake of a Circularly Orbiting Object As an Interpretative Framework of Ubiquitous Spirals and Arcs
Induced Density Circularly Orbiting Interpretative Framework Ubiquitous Spirals

Context. A complex of Hα emitting blobs with strong FUV excess is associated to the dIrr galaxy VCC1217 / IC3418 (Hester et al.2010), and extends up to 17 Kpc in the South-East direction. These outsta...
Evidence for a current sheet forming in the wake of a Coronal Mass Ejection from multi-viewpoint coronagraph observations
Solar and Stellar Astrophysics (astro-ph.SR)

2010/12/23
Ray-like features observed by coronagraphs in the wake of Coronal Mass Ejections (CMEs) are sometimes interpreted as the white light counterparts of current sheets (CSs) produced by the eruption.
Lagrangian transport and chaos in the near wake of the flow around an obstacle:a numerical implementation of lobe dynamics
Lagrangian transport near wake numerical implementation lobe dynamics

2009/11/13
In this paper we study Lagrangian transport in the near wake of the flow around an obstacle, which we take to be a cylinder. In this case, for the range of Reynolds numbers investigated, the flow is t...
