Revealing their origin and evolution is one of the most interesting subjects in the studies of the universe. Deeply understanding these phenomena also provides feedback on cosmology as well as high-energy and high-density physics. The last decades witnessed the great progress in this field. We have now established that stellar collapses produce supernova explosions and sometimes gamma-ray bursts. Stellar explosions release heavy elements into space, which finally result in our life. Expanding ejecta make shocks, leading to particle acceleration and the observed cosmic rays. Compact objects such as black holes and neutron stars are left behind, which act as central engines of high energy emission. At the same time, however, these developments pose new problems. In the 21th century, we will attack these problems by using multi-messengers, i.e., gravitational waves, neutrinos and cosmic rays in addition to photons. In this talk, we will review these progress and problems and discuss future prospects in the high energy astrophysics from my perspective.<\/span><\/div>\n<div><\/div>\n","protected":false},"featured_media":0,"template":"","tags":[],"seminar_category":[55],"acf":{"s_now_accepting":true,"s_date_order":"2017-01-11 17:30:00","s_date_end":null,"s_date_text":"","s_text":"Kunihito Ioka","s_place":"KMI Science Symposia (ES635)","s_place_other":"","s_categoryother":"","s_poster":"","s_poster2":"","s_slide":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.5 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Multi-Messenger Era of High Energy Astrophysics - KMI - Nagoya University<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.kmi.nagoya-u.ac.jp\/eng\/seminar\/999\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Multi-Messenger Era of High Energy Astrophysics - KMI - Nagoya University\" \/>\n<meta property=\"og:description\" content=\"High energy phenomena, such as gamma-ray bursts and cosmic rays, are ubiquitous in the universe.
