本文报道了三个z ~ 2.4-3.4亚毫米波段共用户测辐射阵深场星系的IRAM毫米波干涉测量。我们的CO线观测证实了静止坐标系的UV/光学红移，从而使已证实的微弱亚毫米波红移数量增加了一倍以上，并证明了它们的高z性质。在所有三个来源中，我们对固有气体和动力学质量的测量都很大（1010-1011 M）。至少在两种情况下，数据显示亚毫米波源是相互作用系统的一部分。结合最近在X射线、光学和无线电波段收集的信息，我们的观测结果支持这样的解释，即亚毫米波人口，至少是无线电探测到的人口，由富含气体（气体与动力学质量比约为0.5）和大量相互作用的星暴/活动星系核系统组成。
We report IRAM millimeter interferometry of three z ~ 2.4-3.4 Submillimeter Common-User Bolometric Array deep field galaxies. Our CO line observations confirm the rest-frame UV/optical redshifts, thus more than doubling the number of confirmed published redshifts of the faint submillimeter population and proving their high-z nature. In all three sources our measurements of the intrinsic gas and dynamical mass are large (1010-1011 M☉). In at least two cases the data show that the submillimeter sources are part of an interacting system. Together with recent information gathered in the X-ray, optical, and radio bands, our observations support the interpretation that the submillimeter population, at least the radio-detected ones, consists of gas-rich (gas-to-dynamical mass ratio ~0.5) and massive interacting starburst/active galactic nucleus systems.
