Origin of the forbidden [S II] emission in Mrk 1044’s centre. The left panel shows the Hα surface brightness map where the H0 outflow is located the central 05. The right panel shows the two component model for the inner 05 integrated spectrum where we fixed the host and outflow kinematics to what we found from the 3″ integrated spectrum. For the outflow, we do not find a significant contribution of [S II] and [N II] suggesting that the gas density lies above their critical densities.
