【学术报告】 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 报告题目: Seed Supermassive Black Holes 报告人: Luis C. Ho 报告人单位:KIAA, Peking University 报告语言: 英文 报告时间: 2022年8月29日(星期一)上午10:30-12:00 报告地点: 1号楼502会议室 报告摘要: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Intermediate-mass black holes, with masses ranging from ~100 to a million times the mass of the Sun, are important for understanding the birth of quasars, the contribution of black hole accretion to the epoch of cosmic reionization, the coevolution between AGNs and galaxies, and detection of nano-Hertz gravitational waves. I will review current knowledge of intermediate-mass black holes based on multiwavelength searches over the past 20 years. The occupation fraction of intermediate-mass black holes appears to be substantial in low-mass, late-type galaxies. I will also discuss the potential of JWST to transform this field. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 本通知也可以在云台学术报告网页看到: http://www.ynao.cas.cn/xwzx/xstg/ 申请安排学术报告的同事请参见台学术报告管理办法: http://www.ynao.cas.cn/xwzx/xstg/gzzd/ 云台邀请团组:大样本恒星演化团组、云南天文台学术委员会 邀请方联系人:韩占文13698755218 8月23日
