Abstract
A new method for recovering the properties of bars has been developed and tested using edge-on-oriented N-body representations of barred disk galaxies. We have verified this method with near-face-on oriented barred disk galaxies. This process involves inferring a 3-dimensional mass distribution from a 2-dimensional surface brightness image. The recovered 3D mass distribution is then used to obtain the gravitational potential of the barred system. We use this gravitational potential to construct orbits of 30,000 stars within the system. Each orbit is superposed with different weights to best-fit the 2D surface brightness image and 2D Integral Field Spectroscopic data. We constructed mock data from an N-body simulation of a barred disk galaxy with a moderately weak bar, and were able to correctly recover the bar pattern speed and supermassive black hole mass. Following this success, we apply this method to the barred spiral galaxy, NGC 4371, using data from both SINFONI and MUSE spectrographs.
