At the interface between a supersonic plasma flow and the interstellar or intergalactic medium, complex nonlinear multiscale electromagnetic plasma processes are inferred to heat and accelerate electrons and ions up to highly relativistic speeds. Understanding the mechanisms underpinning the energy channeling between different plasma species through collective processes is crucial to model local spacecraft data and supernovae remnants&#8217; multimessenger signatures. In this presentation, I will outline our recent progress in understanding the energy partition between electrons and ions in collisionless Newtonian high Alfvenic Mach number shock waves. I will present our results on a reduced description of electron transport in a Weibel-mediated microturbulence, energy partition between electrons and ions, and electron acceleration in the shock transition. Our results rely on analytical and semi-analytical descriptions and are supported by large-scale Particle-In-Cell simulations.<br><\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>[\u304a\u554f\u5408\u305b] \u3000cg-sim<img decoding=\"async\" style=\"width: 80px\" src=\"https:\/\/unit.nifs.ac.jp\/research\/wp-content\/themes\/nifs-dev\/img\/img_mail.svg\" alt=\"\"><\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<ul class=\"has-small-font-size wp-block-list\">\n<li>\u8208\u5473\u3092\u304a\u6301\u3061\u306e\u65b9\u306f\u3069\u306a\u305f\u3067\u3082\u3054\u53c2\u52a0\u3044\u305f\u3060\u3051\u307e\u3059\u304c\u3001\u60c5\u5831\u30bb\u30ad\u30e5\u30ea\u30c6\u30a3\u304a\u3088\u3073\u8cbf\u6613\u7ba1\u7406\u306e\u89b3\u70b9\u304b\u3089\u3001\u4e8b\u524d\u7533\u8fbc\u3092\u304a\u9858\u3044\u3057\u307e\u3059\u3002\u304a\u7533\u8fbc\u307f\u306f\u3001\u6c0f\u540d\u3001\u6240\u5c5e\u3001\u8077\u540d\u307e\u305f\u306f\u5b66\u5e74\u3001\u9023\u7d61\u5148\u30e1\u30fc\u30eb\u30a2\u30c9\u30ec\u30b9\u3092\u660e\u8a18\u306e\u4e0a\u3001cg-sim <code><img decoding=\"async\" style=\"width: 60px\" src=\"https:\/\/unit.nifs.ac.jp\/research\/wp-content\/themes\/nifs-dev\/img\/img_mail.svg\" alt=\"\"><\/code>\u307e\u3067\u30e1\u30fc\u30eb\u306b\u3066\u304a\u9001\u308a\u304f\u3060\u3055\u3044\u3002\u6298\u308a\u8fd4\u3057\u53c2\u52a0\u306e\u53ef\u5426\u3068\u63a5\u7d9a\u60c5\u5831\u3092\u304a\u77e5\u3089\u305b\u3057\u307e\u3059\u3002<\/li>\n\n\n\n<li>\u5f53\u65e5\u3001\u53c2\u52a0\u8005\u540d\u7c3f\u3092\u4f5c\u6210\u3057\u307e\u3059\u3002\u540d\u7c3f\u306f\u6cd5\u306b\u57fa\u3065\u3044\u3066\u958b\u793a\u3055\u308c\u308b\u5834\u5408\u304c\u3042\u308a\u307e\u3059\u3002<\/li>\n\n\n\n<li>\u5404\u6240\u5c5e\u5927\u5b66\u30fb\u6a5f\u95a2\u306b\u304a\u3044\u3066\u7814\u7a76\u502b\u7406\u6559\u80b2\u3092\u53d7\u8b1b\u3057\u305f\u4e0a\u3067\u304a\u7533\u3057\u8fbc\u307f\u304f\u3060\u3055\u3044\u3002<\/li>\n<\/ul>\n","protected":false},"author":9,"featured_media":1986,"menu_order":0,"template":"","meta":{"_acf_changed":false,"footnotes":""},"ppma_author":[347],"class_list":["post-4505","news","type-news","status-publish","has-post-thumbnail","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/news\/4505","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/news"}],"about":[{"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/types\/news"}],"author":[{"embeddable":true,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/users\/9"}],"version-history":[{"count":8,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/news\/4505\/revisions"}],"predecessor-version":[{"id":8356,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/news\/4505\/revisions\/8356"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/media\/1986"}],"wp:attachment":[{"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/media?parent=4505"}],"wp:term":[{"taxonomy":"author","embeddable":true,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/ppma_author?post=4505"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
