The temporal evolution of this geometry also provides critical insight into key physical properties of the star-formation process. In this talk, I will address these issues using multi-wavelength observational data, with particular emphasis on recent JCMT\/POL-2 observations of three star-forming regions.<\/div>\n<div dir=\"ltr\"><\/div>\n<\/div>\n<div>\n<div class=\"gmail_signature\" dir=\"ltr\">\n<div dir=\"ltr\">\n<div>\n<div style=\"width: 830px;\" class=\"wp-video\"><!--[if lt IE 9]><script>document.createElement('video');<\/script><![endif]-->\n<video class=\"wp-video-shortcode\" id=\"video-13477-1\" width=\"830\" height=\"467\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"http:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2026\/01\/GMT20260121-200235_Recording_1920x1080.mp4?_=1\" \/><a href=\"http:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2026\/01\/GMT20260121-200235_Recording_1920x1080.mp4\">http:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2026\/01\/GMT20260121-200235_Recording_1920x1080.mp4<\/a><\/video><\/div>\n<\/div>\n<div>\n<hr \/>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div dir=\"ltr\">\n<div dir=\"ltr\">\n<div dir=\"ltr\">\n<div dir=\"ltr\">\n<div dir=\"ltr\">\n<div dir=\"ltr\">\n<div dir=\"ltr\">\n<div>\n<p>Title:\u00a0<b> Initial Conditions of Star Formation<\/b><\/p>\n<div>\n<div dir=\"ltr\">Speaker: <b>Dalei Li (Xinjiang Astronomical Observatory)<\/b><\/div>\n<div dir=\"ltr\"><\/div>\n<div dir=\"ltr\">Abstract:<\/div>\n<div dir=\"ltr\">Stars are believed to form from dense \u00a0collapsing molecular cores.<br \/>\nStudies of these cores provide crucial insights into the initial conditions and earliest stages of star formation.

In this talk, I will introduce two distinct projects we have undertaken that each focus on gaseous environments through different observational approaches. The first part focuses on the gaseous environment in the vicinity of active galactic nuclei (AGNs). In this project, we utilized the infrared flux variability, which is characteristic of the AGN, to distinguish between dusty gas and dust-free gas components around the AGN for the first time, and discussed the radiation-pressure effect on these different gas structures. I will also present our recent results on variability analysis of the broad Halpha line for local AGNs with unique characteristics uncovered by our independent analysis.\u3000The second part focuses on the gaseous environment in submillimeter galaxies (SMGs). In this project, we performed [CII]158\u00b5m observations using ALMA for flux-limited SMG sample at z = 3-5, originally detected by the SCUBA-2 survey. Thanks to the bright nature of our sample, we successfully detected the [CII] line for 16 out of 18 targets with S\/N&gt;10. Most of the detected [CII] lines exhibit complex profiles that reflect the kinematics of [CII]-emitting gas.\u00a0 I will also present our preliminary results regarding correlations between [CII] luminosity and several physical properties, such as star formation rate and molecular gas mass.<\/div>\n<div dir=\"ltr\"><\/div>\n<\/div>\n<\/div>\n<div>\n<div style=\"width: 830px;\" class=\"wp-video\"><video class=\"wp-video-shortcode\" id=\"video-13477-3\" width=\"830\" height=\"445\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"http:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2026\/04\/GMT20260410-020015_Recording_1832x982.mp4?_=3\" \/><a href=\"http:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2026\/04\/GMT20260410-020015_Recording_1832x982.mp4\">http:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2026\/04\/GMT20260410-020015_Recording_1832x982.mp4<\/a><\/video><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>This page lists the Seminars that were given virtually on zoom in 2026.
