AbstractAbstract Using the NSF’s Karl G. Jansky Very Large Array (VLA), we report six detections of CO(J?=?1 → 0) emission and one upper limit in z?=?2–3 galaxies originally detected in higher-J CO emission in the Atacama Large Millimeter/submillimeter Array Spectroscopic Survey in the Hubble Ultra Deep Field (ASPECS). From the CO(J?=?1 → 0) line strengths, we measure total cold molecular gas masses of Mgas?=?(2.4–11.6)?×?1010 (αCO/3.6)M⊙. We also measure a median CO(J?=?3 → 2) to CO(J?=?1 → 0) line brightness temperature ratio of r31?=?0.84?±?0.26, and a CO(J?=?7 → 6) to CO(J?=?1 → 0) ratio range of r71?
