Barred CO emission in HE 1029-1831

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 ~($6\pm2$) kpc. The CO emission shows a strong velocity gradient along the minor axis of the bar (${\rm PA}=90^\circ$). The molecular gas mass is estimated to be ~$1.2\times10^{10}\mathcal{M}_{\odot}$, 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 ~4 kpc from the galactic nucleus.
