No CO emission from Damped Lyman-α absorbers.

BRAINE J., DOWNES D. and GUILLOTEAU S.

Abstract (from CDS):

Recent claimed or tentative detections of CO emission in damped Lyα absorbers towards quasars have been found to be spurious. Our observations, made with the IRAM interferometer, do not suffer from the potential baseline uncertainties inherent in single dish work. Currently, CO has not been detected in any QSO Lyα system. The systems we observed are: PC 1643+4631A, Q 1235+0857, and Q 0836+113.
