Accurate visualization of galaxy velocity fields from three-dimensional integral field spectroscopy data

In recent years, integral field spectroscopy (IFS) has become a major methodology in observational astronomy. Visual analysisof galactic motions is expected to play a crucial role in discovering the physical properties of galaxies. This poster presents anovel method for visualizing galaxy-specific motions using an emerging visual programming environment, Advanced Frameworkfor Learning Astrophysical Knowledge (aflak), for visual analysis of three-dimensional IFS data. We demonstrate that theline-of-sight velocity of each region of galaxies can be more accurately visualized by coupling two specific kinds of aflakmacros for generating position-velocity diagrams and deriving velocity fields.
