    CO /J = 2-1/ observations of southern H II regions
    Maps in the CO (J = 2-1) line of the southern H II region complexes Carina Nebula and G333.6-0.2/RCW 106 are presented and discussed. Results for the Carina...

    CO content of bipolar planetary nebulae
    We report high-sensitivity millimeter-wave CO observations of recently discovered bipolar planetary nebulae (PNe). Three objects (BV 5-1, K 3-94 and K 3-24)...

    CO emission from candidate photo-dissociation regions in M 81
    Context: .At least a fraction of the atomic hydrogen in spiral galaxies is suspected to be the result of molecular hydrogen which has been dissociated by...

    CO emission in distant galaxies on and above the main sequence
    We present the detection of multiple carbon monoxide CO line transitions with ALMA in a few tens of infrared-selected galaxies on and above the main sequence at...

    CO in the ALMA Radio-source Catalogue (ARC): The molecular gas content of radio galaxies as a function of redshift
    To evaluate the role of radio activity in galaxy evolution, we designed a large archival CO survey of radio galaxies (RGs) to determine their molecular gas...

    CO J=1->0 mapping of the cometary nebula 1548c27.
    We have acquired CO J=1->0 mapping of a region 2x2arcmin^2^ about the cometary nebula and jet outflow source 1548c27. We find little evidence for interaction...

    CO, H2O, H2O+ line and dust emission in a z = 3.63 strongly lensed starburst merger at sub-kiloparsec scales
    Using the Atacama Large Millimeter/submillimeter Array (ALMA), we report high angular-resolution observations of the redshift z = 3.63 galaxy H-ATLAS J083051.0...
