This unprecedented level of detail allows scientists to test and validate their pipelines before Euclid\u2019s full data streams become available.&#13;<\/p>\n<p class=\"bodytext\">\u201cThis is a huge step for the scientific community, since it is now accessible for everyone,\u201d added Jorge Carretero, researcher at the Port d\u2019Informaci\u00f3 Cient\u00edfica (PIC) and CIEMAT. \u201cIn addition, it can have many different scientific applications beyond the context of the Euclid mission,\u201d he said according to the press release.&#13;<\/p>\n<p>How the simulation works<\/p>\n<p class=\"bodytext\">The Flagship 2 catalogue was produced on Switzerland\u2019s Piz Daint supercomputer, using custom algorithms developed at the <a href=\"https:\/\/www.notebookcheck.net\/CMV-subreddit-infiltrated-by-bots-for-an-unethical-university-experiment.1007214.0.html\" target=\"_self\" class=\"internal-link\" rel=\"nofollow noopener\">University of Zurich<\/a>. The computation tracked the gravitational evolution of more than four trillion particles to form the cosmic web, clusters, filaments, and voids shaped by both dark and visible matter.&#13;<\/p>\n<p class=\"bodytext\">The project demonstrates the cutting edge of big-data cosmology: petabyte-scale simulations, advanced algorithms, and high-performance computing combined to create a realistic universe. By making the dataset open via CosmoHub, the team is enabling researchers worldwide to explore complex cosmological questions without needing their own supercomputing resources.<\/p>\n","protected":false},"excerpt":{"rendered":"The catalogue describes each galaxy using more than 400 properties, including brightness, shape, velocity, and star formation rate.&hellip;\n","protected":false},"author":2,"featured_media":88401,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[270],"tags":[582,1025,1820,57955,57957,14588,4642,2352,18,6145,57951,57949,57950,57952,57954,1821,19,17,1815,1819,1814,57956,1822,1818,1142,1143,133,451,26824,21418,1817,1816,5610,26082,57953],"class_list":{"0":"post-88400","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-astronomy","9":"tag-astrophysics","10":"tag-benchmarks","11":"tag-cosmic-structures","12":"tag-cosmohub","13":"tag-cosmology","14":"tag-dark-energy","15":"tag-dark-matter","16":"tag-eire","17":"tag-esa","18":"tag-euclid-consortium","19":"tag-euclid-mission","20":"tag-euclid-telescope","21":"tag-flagship-2-simulation","22":"tag-galaxy-simulation","23":"tag-graphics-card","24":"tag-ie","25":"tag-ireland","26":"tag-laptop","27":"tag-netbook","28":"tag-notebook","29":"tag-piz-daint","30":"tag-processor","31":"tag-reports","32":"tag-review","33":"tag-reviews","34":"tag-science","35":"tag-space","36":"tag-space-science","37":"tag-supercomputer","38":"tag-test","39":"tag-tests","40":"tag-universe","41":"tag-university-of-zurich","42":"tag-virtual-universe"},"share_on_mastodon":{"url":"","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/88400","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=88400"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/88400\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/88401"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=88400"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=88400"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=88400"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
