Presentation #341.06 in the session AGN and Quasars.
Active galactic nuclei (AGNs) are thought to be strongly connected to galaxy evolution, as they may provide feedback which affects star formation; therefore, it is important to gain a better understanding of how AGNs affect their host galaxies. To this end, we analyze MUSE/Very Large Telescope integral field spectroscopy data on the active spiral galaxy NGC 5806. This is a nearby galaxy (z=0.00449) with an active black hole and is classified as a Seyfert 2 galaxy. The MUSE data was taken with one hour of exposure time in the optical range, with very fine spatial sampling (0.623 arcsec sky resolution) and a spectral resolution of 1.25 angstroms. We process the data using Voronoi binning, and use pPXF to fit spectral features throughout the field of view. From the results, we model the gas emission dynamics and stellar kinematics, and identify high-ionization gas emission within the central 7 by 7 kpc of the galaxy. In this presentation I will show 2D maps of emission line ratios, to show where gas excitation is due to AGN or star formation and how far the AGN excitation of the gas reaches. I will also present the dynamics of gas in the nucleus in the galaxy and discuss how they are affected by the AGN.
