黄家声,国家天文台研究员,博导。黄家声研究员于1985年获南京大学学士学位,1997年获美国夏威夷大学博士学位,1997-1999年期间在德国马普天文研究所从事博士后研究工作,1999至2017年在美国哈佛-史密松森天体物理中心任高级科学家,2017年起任中国科学院南美天文研究中心首席科学家。主要研究领域为星系形成与演化,高红移宇宙。摘要:
We use a set of local galaxy MIR templates to fit SEDs of a 16micron selected galaxy sample. The fitting permits dissecting a galaxy MIR emission: AGN, SF, and old stellar population. We are able to solve a set of equations to separate AGN and SF luminosity in these galaxies. This will allow us to study galaxy massive BL co-evolution. We found AGNs happen in galaxies above the main sequence line with lower stellar mass. We argue that AGN may occur in starburst stage and quench quickly before quenching star formation!
