Gas motions mapping for three Seyfert galaxies

TL;DR

This study uses 3D spectroscopy to map gas motions in three Seyfert galaxies, revealing nuclear outflows and jet-associated ionized gas dynamics in their central regions.

Contribution

It presents new kinematic maps of Seyfert galaxies using integral-field spectroscopy and Fabry-Perot interferometry, highlighting nuclear outflows and jet interactions.

Findings

Detection of nuclear outflows in all three galaxies.

Identification of ionized gas motions linked to radio jets.

Construction of detailed velocity fields in emission lines.

Abstract

We report preliminary results of a kinematical study for three Seyfert galaxies selected from a sample of nearby active galactic nuclei observed using 3D spectroscopy. The observations were performed at the prime focus of the SAO RAS 6-m telescope with the integral-field spectrograph MPFS and with a scanning Fabry-Perot interferometer, installed on the multimode device SCORPIO. Based on these data, the monochromatic maps and velocity fields in different emission lines were constructed. We have detected a nuclear outflow or ionized gas motions associated with a radio jet in all galaxies circumnuclear regions.
