检验SMG和类星体之间的演化联系：亚毫米波探测到的z~2的类星体是这两个阶段之间的“过渡天体”吗？
Testing the Evolutionary Link Between SMGs and QSOs: are Submm-Detected QSOs at z~2 `Transition Objects' Between These Two Phases?
摘要：
局部球状体显示出它们的质量与它们中心的超大质量黑洞（SMBH）的质量之间的关系，表明球状体生长的主要阶段与核吸积之间的联系。这些阶段可能对应于高z亚毫米星系（SMG）和类星体，具有惊人相似的红移分布的独立群体，可能都是单个星系生命周期中的阶段，SMG演变成类星体。在这里，我们简要地讨论了我们最近在Coppin等人（2008）中的结果，在那里，我们已经通过称量黑洞和映射CO在亚毫米探测到的类星体（可能是两个阶段之间的过渡物体）中的重量来测试这种联系，并将它们的重子，动力学和Halpha-derived SMBH质量与SMG在同一时期的质量进行比较。[删节]
英文摘要：
Local spheroids show a relation between their masses and those of the super-massive black holes (SMBH) at their centres, indicating a link between the major phases of spheroid growth and nuclear accretion. These phases may correspond to high-z submillimetre galaxies (SMGs) and QSOs, separate populations with surprisingly similar redshift distributions which may both be phases in the life cycle of individual galaxies, with SMGs evolving into QSOs. Here we briefly discuss our recent results in Coppin et al. (2008), where we have tested this connection by weighing the black holes and mapping CO in submm-detected QSOs, which may be transition objects between the two phases, and comparing their baryonic, dynamical and Halpha-derived SMBH masses to those of SMGs at the same epoch.
