TL;DR: Rakshit et al. as discussed by the authors showed a correlation between the size of the broad line region (BLR) and the monochromatic continuum luminosity at 5100 AA, allowing black hole mass estimation based on single-epoch spectra.

TL;DR: In this paper, the authors used the Gemini Multi-Object Spectrograph (GMS) to study the ionization properties and energetics of AGN-driven outflows and found strong evidence that connect the extreme kinematics of the ionized gas with the AGN photoionization.

Abstract: AGN-driven outflows are considered as one of the processes driving the co-evolution of supermassive black holes with their host galaxies. We present integral field spectroscopy of six Type 2 AGNs at z < 0.1, which are selected as AGNs without strong outflows based on the kinematics of [Oiii] gas. Using spatially resolved data, we investigate the ionized gas kinematics and photoionization properties in comparison with AGNs with strong outflows. We find significant differences between the kinematics of ionized gas and stars for two AGNs, which indicates the presence of AGN-driven outflows. Nevertheless, the low velocity and velocity dispersion of ionized gas indicate relatively weak outflows in these AGNs. Our results highlight the importance of spatially-resolved observation in investigating gas kinematics and identifying the signatures of AGN-driven outflows. While it is unclear what determines the occurrence of outflows, we discuss the conditions and detectability of AGN-driven outflows based on a larger sample of AGNs with and without outflows, suggesting the importance of gas content in the host galaxies.

TL;DR: In this article, the authors investigated the ionized gas kinematics based on the [O III] λ$5007 emission line along the large-scale radio jet for six radio AGNs.
