Powerful ionized gas outflows in the interacting radio galaxy 4C +29.30

Abstract

We investigate the ionized gas excitation and kinematics in the inner $4.3\times 6.2$ kpc${}^2$ of the merger radio galaxy 4C +29.30. Using optical integral field spectroscopy with the Gemini North Telescope, we present flux distributions, line-ratio maps, peak velocities and velocity dispersion maps as well as channel maps with a spatial resolution of $\approx 955$ pc. We observe high blueshifts of up to $\sim -650$ km s${}^{-1}$, in a region $\sim 1^{\prime \prime }$ south of the nucleus (the southern knot, SK), which also presents high velocity dispersions ($\sim 250$ km s${}^{-1}$), which we attribute to an outflow. A possible redshifted counterpart is observed north from the nucleus (the northern knot, NK). We propose that these regions correspond to a bipolar outflow possibly due to the interaction of the radio jet with the ambient gas. We estimate a total ionized gas mass outflow rate of ${\dot{M}}_{out}=25.4\begin{array}{c}+11.5\\ -7.5\end{array}$ M${}_{\odot }$ yr${}^{-1}$ with a kinetic power of $\dot{E}=8.1\begin{array}{c}+10.7\\ -4.0\end{array}\times 10^{42}$ erg s${}^{-1}$, which represents $5.8\begin{array}{c}+7.6\\ -2.9\end{array}\%$ of the AGN bolometric luminosity. These values are higher than usually observed in nearby active galaxies with the same bolometric luminosities and could imply a significant impact of the outflows in the evolution of the host galaxy. The excitation is higher in the NK (that correlates with extended X-ray emission, indicating the presence of hotter gas) than in the SK, supporting a scenario in which an obscuring dust lane is blocking part of the AGN radiation to reach the southern region of the galaxy.
