A galaxy sample with CO(2-1) and CO(5-4) detections

We study the carbon monoxide (CO) excitation, mean molecular gas density, and interstellar radiation field (ISRF) intensity in a comprehensive sample of 76 galaxies from local...本研究针对取自本地的76个星系组成的综合样本，对其中的一氧化碳（carbon monoxide, CO）激发、平均分子气体密度以及星际辐射场（interstellar radiation field, ISRF）强度展开了研究。
