The first source can be associated with SS 433\u2019s eastern jet lobe, whereas the second source is variable and displays significant periodicity that is compatible with the precession period of the binary system, of about 160 days. The location of this variable component is not<br>compatible with the location\/extrapolation of SS 433 jets. To explain<br>the observed phenomenology, a scenario based on the illumination of<br>dense gas clouds by relativistic protons accelerated at the interface<br>of the accretion disk envelope has been proposed. Energetic arguments<br>strongly constrain this scenario, however, as it requires an unknown<br>mechanism capable to periodically channel a large fraction of SS 433\u2019s<br>kinetic energy towards an emitter located 35 parsec away from the<br>central binary system.<br><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Coloquio:19 de octubre 2020 &#8211; 11:00 horas Expositor: Pol Bordas, Universidad de Barcelona Resumen:\u00a0The detection of two sources of gamma rays towards the microquasar SS 433 has been recently reported &#8230;<\/p>\n","protected":false},"author":3,"featured_media":25277,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[14,13],"tags":[],"class_list":["post-14846","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-coloquios","category-novedades"],"_links":{"self":[{"href":"https:\/\/www.iar.unlp.edu.ar\/index.php\/wp-json\/wp\/v2\/posts\/14846","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iar.unlp.edu.ar\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.iar.unlp.edu.ar\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.iar.unlp.edu.ar\/index.php\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iar.unlp.edu.ar\/index.php\/wp-json\/wp\/v2\/comments?post=14846"}],"version-history":[{"count":1,"href":"https:\/\/www.iar.unlp.edu.ar\/index.php\/wp-json\/wp\/v2\/posts\/14846\/revisions"}],"predecessor-version":[{"id":22490,"href":"https:\/\/www.iar.unlp.edu.ar\/index.php\/wp-json\/wp\/v2\/posts\/14846\/revisions\/22490"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.iar.unlp.edu.ar\/index.php\/wp-json\/wp\/v2\/media\/25277"}],"wp:attachment":[{"href":"https:\/\/www.iar.unlp.edu.ar\/index.php\/wp-json\/wp\/v2\/media?parent=14846"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iar.unlp.edu.ar\/index.php\/wp-json\/wp\/v2\/categories?post=14846"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iar.unlp.edu.ar\/index.php\/wp-json\/wp\/v2\/tags?post=14846"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
