Contribution

It provides new insights into the kinematics of ionized gas and stars in Mrk334, highlighting the role of merging processes in triggering AGN activity.

Findings

Merging processes are linked to AGN activation in Mrk334.

Ionized gas and stellar kinematics show signs of interaction.

Diagnostic diagrams suggest merger-induced gas dynamics.

Abstract

We have studied the kinematics of the ionized gas and stellar component in Mrk334 using methods of panoramic (3D) spectroscopy. The observations were performed at the prime focus of the SAO RAS 6-m telescope with the integral-field spectrograph MPFS (Afanasiev et al. 2001) and with a scanning Fabry-Perot interferometer (FPI), installed on the multimode device SCORPIO (Afanasiev & Moiseev 2005). Based on these data, the monochromatic maps and velocity fields in different emission lines of the ionized gas were constructed. The diagnostic diagrams have been made based on the emission lines ratios.
