AGN抑制早型星系中的恒星形成吗?

Do AGN suppress star formation in early-type galaxies?

Kevin Schawinski

摘要:

活动星系核的宿主星系优先居住在蓝色云和红色序列之间的“绿色山谷”的观察对于我们理解星系和黑洞通过吸积事件的共同演化具有重要意义。我讨论了绿谷活动星系核的宿主星系的颜色,特别侧重于早期型星系的解释。

英文摘要:

The observation that AGN host galaxies preferentially inhabit the "green valley" between the blue cloud and the red sequence has significant consequences for our understanding of the co-evolution of galaxies and black holes via accretion events. I discuss the interpretation of green valley AGN host galaxy colours with particular focus on early-type galaxies.
