Description
According to numerical models, feedback from accreting supermassive black holes plays a central role in the evolution of galaxies. Kinetic feedback (or radio/jet-mode) is the most important form of AGN feedback in low accretion rate AGNs (i.e., the majority of AGN) and, therefore, it has a major impact on the evolution of most galaxies. Stephan’s Quintet was targeted by JWST Early Release Observations and JWST/MIRI mid-IR spectroscopy was obtained for NGC 7319, the largest spiral in the group, which hosts a type 2 Seyfert AGN with a low-power radio jet. The JWST data analysis reveals a clear jet-ISM interac- tion, which is decelerating the relativistic jet and producing strong hot/warm molecular H_2 emission. We present preliminary results obtained using MEGARA/GTC to characterize the kinematics and physical conditions of the ionized phase of this textbook example of a jet-ISM interaction. The study of optical emission lines in several bands covering several ionization states and sensitive to different physical conditions allows us to characterize the shocked regions, the so-called N2 and S2 spots previously found. A multi-component approach is taken to properly characterize the systemic and the ionized gas outflow components and to derive the velocity and the size of the outflow as well as its mass, momentum and kinetic energy.
