The research team conducted a systematic observation and analysis centered on the Japanese X-ray astronomical satellite, Suzaku, for five years since 2013. It became clear how the now-calm galaxy actively repeated explosions 10 million years ago and went through extreme evolution.<br \/>\nTheir research was published in <em>The Astrophysical Journal<\/em> on July 25, 2018.<\/p>\n<h4>Reference<\/h4>\n<ul>\n<li><a href=\"http:\/\/iopscience.iop.org\/article\/10.3847\/1538-4357\/aacd08\/meta\">Diffuse X-Ray Emission from the Northern Arc of Loop I Observed with Suzaku<\/a><\/li>\n<li>Masahiro Akita, <a href=\"http:\/\/researchers.waseda.jp\/profile\/en.014948633d287db78ae24a35877a1297.html\">Jun Kataoka<\/a>, Makoto Arimoto, Yoshiaki Sofue, Tomonori Totani, Yoshiyuki Inoue, and Shinya Nakashima<\/li>\n<li>Published in <em>The Astrophysical Journal<\/em> on July 25, 2018<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Approaching the mystery of the Fermi bubble, the Galactic center Researchers from Waseda University, the Unive [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":66101,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[95],"tags":[73,179],"class_list":["post-61046","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-en","tag-general-en","tag-research-en"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/posts\/61046","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/comments?post=61046"}],"version-history":[{"count":2,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/posts\/61046\/revisions"}],"predecessor-version":[{"id":66102,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/posts\/61046\/revisions\/66102"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/media\/66101"}],"wp:attachment":[{"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/media?parent=61046"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/categories?post=61046"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/tags?post=61046"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
