发布时间：2019-03-15 15:14
【摘要】：2015年,以中国天文学家为主的国际研究团队宣布发现了目前已知的宇宙早期发光本领最强、中心黑洞质量最大的类星体。这颗类星体SDSS J0100+2802如同一座最明亮的灯塔照亮了人类探索神秘的早期宇宙的道路,它的发现刷新了人类使用2米级望远镜发现高红移类星体的纪录,更对宇宙早期黑洞的成长理论提出了新的挑战。文章将着重介绍:(1)类星体的发现;(2)类星体的本质以及描述其物理性质的参数;(3)研究类星体的重大科学意义;(4)类星体尤其是高红移类星体的搜寻方法;(5)最亮的高红移类星体的发现历程;(6)对今后高红移类星体研究的展望。
[Abstract]:In 2015, an international research team, led by Chinese astronomers, announced the discovery of the most powerful, central black hole known to date as quasars with the strongest early luminous power and the largest mass of central black holes. This quasar, SDSS J0100 2802, like one of the brightest lighthouses, illuminates the path of mankind to explore the mysterious early universe. Its discovery sets a record for the discovery of Gao Hong's quasar using a 2m telescope. It also presents a new challenge to the theory of the growth of black holes in the early stage of the universe. This paper will focus on: (1) the discovery of quasars; (2) the nature of quasars and the parameters describing their physical properties; (3) the great scientific significance of studying quasars; (4) the search methods of quasars, especially Gao Hong's quasars; (5) the discovery of the brightest high redshift quasars; (6) the prospect of Gao Hong's quasars in the future.
