Galactic structure is not well defined in this region of the Galaxy, and the high-resolution dense molecular gas observed at the JCMT has previously shown to be very efficient at tracing Galactic structure.<\/li>\n<\/ol>\n<div id=\"attachment_12359\" style=\"width: 840px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2021\/12\/Figure1.jpg\"><img aria-describedby=\"caption-attachment-12359\" loading=\"lazy\" class=\"size-large wp-image-12359\" src=\"http:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2021\/12\/Figure1-1024x320.jpg\" alt=\"\" width=\"830\" height=\"259\" srcset=\"https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2021\/12\/Figure1-1024x320.jpg 1024w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2021\/12\/Figure1-300x94.jpg 300w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2021\/12\/Figure1-768x240.jpg 768w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2021\/12\/Figure1-1536x480.jpg 1536w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2021\/12\/Figure1-2048x640.jpg 2048w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2021\/12\/Figure1-150x47.jpg 150w\" sizes=\"(max-width: 830px) 100vw, 830px\" \/><\/a><p id=\"caption-attachment-12359\" class=\"wp-caption-text\"><sup>12<\/sup>CO J=3-2 intensity from a patch of the CHIMPS2 Outer Galaxy data.<\/p><\/div>\n<p style=\"text-align: right\"><strong>Coordinators:<\/strong> <span dir=\"ltr\" role=\"presentation\">David Eden (UK), Harriet Parsons (EAO), Erik <\/span><span dir=\"ltr\" role=\"presentation\">Rosolowsky (Canada), Kee-Tae Kim (South Korea), Yang Su (China), Tetsuhiro Minamidani (Japan),<\/span><span dir=\"ltr\" role=\"presentation\">\u00a0and Vivien Chen (Taiwan) .<\/span><\/p>\n<p style=\"text-align: right\"><strong>\u00a0JCMT program code: M22AL003<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Determining the nature of Outer Galaxy star formation This project has been awarded 416 hours to extend and complement the CHIMPS, CHIMPS2 and COHRS surveys by completing 12CO J=3-2 observations in the longitude range \u2113 = 198\u00b0-236\u00b0.
