Spatially Resolved Spectroscopy of Narrow-line Seyfert 1 Host Galaxies

Scharwächter, Julia; Husemann, B; Busch, G; Komossa, S; Dopita, Michael


We present optical integral field spectroscopy for five $z\lt 0.062$ narrow-line Seyfert 1 (NLS1) galaxies, probing their host galaxies at $\gtrsim 2\mbox{--}3\,\mathrm{kpc}$ scales. Emission lines from the active galactic nucleus (AGN) and the large-scale host galaxy are analyzed separately, based on an AGN–host decomposition technique. The host galaxy gas kinematics indicates large-scale gas rotation in all five sources. At the probed scales of $\gtrsim 2\mbox{--}3\,\mathrm{kpc}$, the host...[Show more]
