黎冠峰教授主講:「愛因斯坦的信使：探視宇宙的新窗戶」 | Prof. Tjonnie Li "Einstein’s Messenger: A New Window on the Universe"

On 11 February, the Laser Interferometer Gravitational-wave Observatory (LIGO) officially announced that the gravitational waves from colliding black holes 1.3 billion years ago have been detected by both of its twin detectors, opening up a new window on the study of the Universe. Prof. Tjonnie G. F. LI, Research Assistant Professor from the Department of Physics at CUHK, has been involved with the work of LIGO since 2009, and is currently the only scientist from a Hong Kong institution to be part of it. In the talk entitled ‘Einstein’s Messenger: A New Window on the Universe’, Prof. Li gave a detailed introduction on gravitational waves and the operation of LIGO. 今年2月11日，鐳射干涉儀重力波觀測站（LIGO）合作組正式宣布，成功探測到兩個黑洞在13億年前合併時所產生的重力波。這是人類第一次探測到重力波，為進一步揭開宇宙起源之謎奠下重要里程碑。中大物理系研究助理教授黎冠峰教授自2009年開始就參與LIGO的研究工作，是LIGO合作組中唯一來自香港院校的科學家。 在講座中，黎教授詳細介紹了重力波以及LIGO的運作。
