Every galaxy with a central bulge has a supermassive black hole (SMBH), and SMBHs can inject energy by jets and shocks that can be observed in radio and X-rays. These energy produced during the growth of SMBHs could affect the growth of the host galaxy. In this study, we focused on NGC 4636, which is a red giant elliptical galaxy in the galaxy cluster Virgo. NGC 4636 has an active galactic nucleus (AGN) that is an extremely bright region at the center. We organized and reduced the optical integral field spectroscopy data from the Multi Unit Spectroscopic Explorer (MUSE) instrument with the existing pipelines. By using this processed data, we produced flux and kinematic maps of warm ionized gas such as H⍺ and [NII] to trace the imprint of the SMBH feedback.The emission lines of these gasses can be used to see motions in the galaxy and locations where it is relatively active in star formation, that leads us perform further analysis of the stellar population of NGC 4636.
