| dc.description.abstract | This work focuses on generating a new dynamical model of the nearby (9.5 Mpc) interacting galaxy system NGC 1512/1510. Neutral hydrogen (H i ) observations from the Australia Telescope Compact Array (ATCA) are used to model the dynamics of the main H i disk using two routines, the two and three-dimensional modeling techniques. For the two-dimensional modeling technique, we adopt ROTCUR which is based on fitting a tilted ring model onto the 2D velocity field of the galaxy. The three-dimensional modeling routine used is 3DBarolo, which is a recently developed algorithm of fitting 3D tilted ring model to the full data cube. We note that the 2D approach fails to model the inclination profile of NGC 1512. Thus, a new rotation curve is generated using the three-dimensional modeling routine only i.e. by fitting a 3D tilted ring model to the H i line data cube of NGC 1512/1510. | en_US |
