Over the next decade, we will\u2028be developing a program using Rubin Observatory&#8217;s Legacy Survey of Space and Time (LSST) to identify SNe that can be subsequently observed with other telescopes in order to obtain spectroscopic typing and redshifts. The spectroscopic follow-up will provide a well-calibrated, precision sample for probing dark energy.<\/p>\n<h3 style=\"text-align:center\"><a href=\"\/cosmo\/\">Back to Cosmology Home<\/a><\/h3>\n","protected":false},"excerpt":{"rendered":"<p>The Supernova Cosmology Project Our Type Ia SNe research program discovered dark energy in the late 1990s and continues to study SNe from ground- and space-based telescopes to improve the measurement of dark energy and extend it to higher redshifts. &hellip;<\/p>\n<p class=\"read-more\"> <a class=\"more-link\" href=\"https:\/\/www.physics.lbl.gov\/cosmo\/type-ia\/\"> <span class=\"screen-reader-text\">Type Ia<\/span> Read More &raquo;<\/a><\/p>\n","protected":false},"author":7,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"_links":{"self":[{"href":"https:\/\/www.physics.lbl.gov\/cosmo\/wp-json\/wp\/v2\/pages\/287"}],"collection":[{"href":"https:\/\/www.physics.lbl.gov\/cosmo\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.physics.lbl.gov\/cosmo\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.physics.lbl.gov\/cosmo\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/www.physics.lbl.gov\/cosmo\/wp-json\/wp\/v2\/comments?post=287"}],"version-history":[{"count":12,"href":"https:\/\/www.physics.lbl.gov\/cosmo\/wp-json\/wp\/v2\/pages\/287\/revisions"}],"predecessor-version":[{"id":367,"href":"https:\/\/www.physics.lbl.gov\/cosmo\/wp-json\/wp\/v2\/pages\/287\/revisions\/367"}],"wp:attachment":[{"href":"https:\/\/www.physics.lbl.gov\/cosmo\/wp-json\/wp\/v2\/media?parent=287"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
