【摘要】：2015年,以中國(guó)天文學(xué)家為主的國(guó)際研究團(tuán)隊(duì)宣布發(fā)現(xiàn)了目前已知的宇宙早期發(fā)光本領(lǐng)最強(qiáng)、中心黑洞質(zhì)量最大的類星體。這顆類星體SDSS J0100+2802如同一座最明亮的燈塔照亮了人類探索神秘的早期宇宙的道路,它的發(fā)現(xiàn)刷新了人類使用2米級(jí)望遠(yuǎn)鏡發(fā)現(xiàn)高紅移類星體的紀(jì)錄,更對(duì)宇宙早期黑洞的成長(zhǎng)理論提出了新的挑戰(zhàn)。文章將著重介紹:(1)類星體的發(fā)現(xiàn);(2)類星體的本質(zhì)以及描述其物理性質(zhì)的參數(shù);(3)研究類星體的重大科學(xué)意義;(4)類星體尤其是高紅移類星體的搜尋方法;(5)最亮的高紅移類星體的發(fā)現(xiàn)歷程;(6)對(duì)今后高紅移類星體研究的展望。
[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.
