一些已经提出的用于解释球状星系团(GC)内多个星团的形成情景要求年轻的大质量星系团内有大量的冷气体储存库，这是形成未来几代恒星所必需的。本文利用阿塔卡马大毫米/亚毫米阵列(ALMA)的深度观测，估计了天线星系中三个年轻的(50-200Myr)质量(类似于10(6)M圆点)星系团内的分子气体量。没有发现与这三个星团中的任何一个相关的显著的CO(3-2)排放。我们将分子气体的上限设置在这些类似于1×10(5)M圆点(或
Some formation scenarios that have been put forward to explain multiple populations within globular clusters (GCs) require that the young massive cluster have large reservoirs of cold gas within them, which is necessary to form future generations of stars. In this paper, we use deep observations taken with Atacama Large Millimeter/submillimeter Array (ALMA) to assess the amount of molecular gas within three young (50-200 Myr) massive (similar to 10(6) M-circle dot) clusters in the Antennae galaxies. No significant CO(3-2) emission was found associated with any of the three clusters. We place upper limits for the molecular gas within these clusters of similar to 1 x 10(5) M-circle dot (or
