- Physical Properties of the Circumnuclear Starburst Ring in the Barred Galaxy NGC 1097
- Abstract
- We report high-resolution 12CO(J = 2-1), 13CO(J = 2-1), and 12CO(J = 3-2) imaging of the Seyfert 1/starburst ring galaxy NGC 1097 with the SMA to study the physical and kinematic properties of the 1 kpc circumnuclear starburst ring. Individual star clusters as detected in the HST map of Paα line emission have been used to determine the star formation rate (SFR), and are compared with the properties of the molecular gas. The molecular ring was resolved into individual clumps at the giant molecular cloud association (GMA) scale of 200-300 pc in all three CO lines. The intersection between the dust lanes and the starburst ring, which is associated with the orbit-crowding region, is resolved into two physically/kinematically distinct features in the 1.5 × 1.0 (105 × 70 pc) CO(J = 2-1) map. The clumps associated with the dust lanes have broader line widths, higher surface gas densities, and lower SFRs, while the narrow line clumps associated with the starburst ring have opposite characteristics. The line widths and surface density of the gas mass of the clumps show an azimuthal variation related to the large-scale dynamics. The SFR, on the other hand, is not significantly affected by the dynamics, but has a correlation with the intensity ratio of 12CO (J = 3-2) and 12CO(J = 2-1), which traces the denser gas associated with star formation. Our resolved CO map, especially in the orbit-crowding region, observationally demonstrates for the first time that the physical/kinematic properties of GMAs are affected by the large-scale bar-potential dynamics in NGC 1097.

- NANTENの成果について
- Abstract
- We have been observing the interstellar molecular clouds in the southern sky with the NANTEN 4m telescope located in Chile since 1996. The observations have covered the largest sky area in the interstellar CO emission, and led to discoveries including “Frequent high-mass star formation triggered by cloud collisions”, “Magnetic activity in the Galactic centre; the central jet and the magnetic flotation loops”, “The giant molecular clouds in the Magellanic clouds” and “The origin of cosmic ray protons in supernova remnants”. I will present the highlight of these results as well as the on-going project NASCO which aims at observing the foreground component of the cosmic microwave background radiation.
