资源简介:
Whereas supermassive black holes openParSMBHsclosePar are found in essentially every galactic bulge comma very few SMBHs are known in purely bulgeless galaxies. Identifying such a population is crucial to our understanding of the origins of SMBHs and the secular pathways for their growth. However comma to date comma there are only a handful of confirmed SMBHs in purely bulgeless galaxies known in the Universe. We have identified a population of bulgeless galaxies that display extreme red mid-infrared colors thus far exclusively associated in extragalactic sources with powerful AGNs and hidden broad line in several targets comma despite showing no evidence for accretion activity. We request XMM observations to confirm the AGNs anddetermine their luminosites.
