我们展示了 IRAM 30 m 望远镜对从 CLoGS 邻近星系群样本中选出的 11 个星系群中的 CO(1–0) 和 (2–1) 线进行的观测。我们的观测证实了 11 个星系中的 4 个星系中存在分子气体,显着性大于 4σ,并将这些与文献中的数据相结合,我们发现检测率为 43 ± 14%,与附近射电星系的检测率相当,这表明群主导椭圆星系可能比群主导椭圆星系更可能含有分子气体。
We present IRAM 30 m telescope observations of the CO(1–0) and (2–1) lines in a sample of 11 group-dominant elliptical galaxies selected from the CLoGS nearby groups sample. Our observations confirm the presence of molecular gas in 4 of the 11 galaxies at >4σ significance, and combining these with data from the literature we find a detection rate of 43 ± 14%, comparable to the detection rate for nearby radio galaxies, suggesting that group-dominant ellipticals may be more likely to contain molecular gas than
