Abstract
This paper presents the observed data from the rotation curve of NGC 4651 galaxy from Very Large Array (VLA) and examine the results from isothermal and Bose–Einstein Condensate models. It is found that both models can be closed to the derived rotation curve from observations for this source. By fitting the observed rotation curve with the expectation models, the mass of halo from models is about 2 × 1011 M⊚. Hence, NGC 4651 galaxy can be dominated by the invisible matter.
