CO(3→2) observations toward the dust lane in Centaurus A
Presenter: Takeshi Okuda (Nagoya Univesity)
Abstract: We successfully resolved the dust lane of Centaurus A (NGC 5128), that is the nearest radio galaxy (D = 3.4 Mpc), at an angular resolution of 24 arcsec (400 pc) by observing the CO (J = 3→2) emission with the sub-mm telescope ASTE. Our wide-field map of this emission in the 7 × 3 arcmin (or 7 × 3 kpc) region is well coincident with that of dust emissions obtained by Spitzer telescope. Since our results showed kinematics of the dust warped disk, we will discuss kinematics and physical properties in the dust lane of Centaurus A.
