Chemical abundances in Seyfert galaxies – V. The discovery of shocked emission outside the AGN ionization axis

We present maps for the electron temperature in the inner kpc of three luminous Seyfert galaxies: Mrk 79, Mrk 348, and Mrk 607 obtained from Gemini GMOS-IFU observations at spatial resolutions of ∼110-280 pc. We study the distributions of electron temperature in active galaxies and find temperatures...

description We present maps for the electron temperature in the inner kpc of three luminous Seyfert galaxies: Mrk 79, Mrk 348, and Mrk 607 obtained from Gemini GMOS-IFU observations at spatial resolutions of ∼110-280 pc. We study the distributions of electron temperature in active galaxies and find temperatures varying in the range from 8000 to ≳30000 K. Shocks due to gas outflows play an important role in the observed temperature distributions of Mrk 79 and Mrk 348, while standard photoionization models reproduce the derived temperature values for Mrk 607. In Mrk 79 and Mrk 348, we find direct evidence for shock-ionization with overall orientation orthogonal to the ionization axis, where shocks can be easily observed as the AGN radiation field is shielded by the nuclear dusty torus. This also indicates that even when the ionization cones are narrow, the shocks can be much wider-angle.
