Barred CO emission in HE1029-1831
  We present CO(1-0) and CO(2-1) line emission maps of the barred spiral active galaxy HE1029-1831 (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=90degree). The molecular gas mass is estimated to be ~1.2x10^(10)Msun 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.
