  • DERIVATION OF THE ROTATION CURVE AND MASS ESTIMATION OF THE CENTRAL REGION OF SPIRAL GALAXY NGC4945

説明

The spiral galaxy NGC4945 is a characteristic galaxy with an active galactic nucleus and active starbursts. In this paper, the CO emission lines from the central region of NGC 4945 observed by ALMA are used for image analysis and mass determination from rotation curves. Two arms extending north-south and two bars extending east-west were observed in the image analysis in the 581-619 km/s integrated intensity diagram. The mass estimate of the central region shows a mass of 1.2 × 10^9 M_⦿ within 9'' (≈166 pc) of the CO(J=1-0) emission line rotation curve.
