Abstract (from CDS):

We present CO(1-0) and CO(2-1) line emission maps of the barred spiral active galaxy HE 1029-1831 (z=0.0403) obtained with the IRAM Plateau de Bure Interferometer (PdBI) and in part by the Berkeley-Illinois-Maryland Association (BIMA) observatory. The CO emission is well associated with the optical bar and extended along it. The FWHM of the CO emission is estimated to be ~(6±2)kpc. The CO emission shows a strong velocity gradient along the minor axis of the bar (PA=90°). The molecular gas mass is estimated to be ∼1.2x1010M which indicates a very gas rich host galaxy. Most of the molecular gas appears to be subthermally excited and cold but we also find weak evidence for a warmer and/or denser gas component at the southern part of the bar emission, about ∼4kpc from the galactic nucleus.
