In this work, we investigate the strength and impact of ionized gas outflows within z ∼ 0.04 MaNGA galaxies. We find evidence for outflows in 322 galaxies ($12{{\ \rm per\ cent}}$ of the analysed line-emitting sample), 185 of which show evidence for hosting an active galactic nucleus (AGN). Most outflows are centrally concentrated with a spatial extent that scales sublinearly with Re. The incidence of outflows is enhanced at higher masses, central surface densities, and deeper gravitational potentials, as well as at higher star formation rate (SFR) and AGN luminosity. We quantify strong correlations between mass outflow rates and the mechanical drivers of the outflow of the form $\dot{M}_{\rm out} \propto \rm SFR^{0.97}$ and $\dot{M}_{\rm out} \propto L_{\rm AGN}^{0.55}$. We derive a master scaling relation describing the mass outflow rate of ionized gas as a function of M⋆, SFR, Re, and LAGN. Most of the observed winds are anticipated to act as galactic fountains, with the fraction of galaxies with escaping winds increasing with decreasing potential well depth. We further investigate the physical properties of the outflowing gas finding evidence for enhanced attenuation in the outflow, possibly due to metal-enriched winds, and higher excitation compared to the gas in the galactic disc. Given that the majority of previous studies have focused on more extreme systems with higher SFRs and/or more luminous AGN, our study provides a unique view of the non-gravitational gaseous motions within ‘typical’ galaxies in the low-redshift Universe, where low-luminosity AGN and star formation contribute jointly to the observed outflow phenomenology.

MaNGA 中电离气体流出的发生率、比例关系和物理条件

在这项工作中，我们研究了 z ∼ 0.04 MaNGA 星系内电离气体流出的强度和影响。我们在 322 个星系中发现了流出的证据（占分析的线发射样本的 12{{\ \rm per\ cent}}$），其中 185 个显示了存在活动星系核 (AGN) 的证据。大多数流出集中在空间范围内，与 Re 呈亚线性比例。在更高的质量、中心表面密度和更深的引力势以及更高的恒星形成率（SFR）和活动星系核光度下，外流的发生率会增加。我们量化了质量流出率与 $\dot{M}_{\rm out} \propto \rm SFR^{0.97}$ 和 $\dot{M}_{\ 形式的流出的机械驱动力之间的强相关性rm out} \propto L_{\rm AGN}^{0.55}$. 我们推导出一个主标度关系，将电离气体的质量流出速率描述为 M⋆、SFR、Re 和 LAGN 的函数。大多数观测到的风预计将充当银河喷泉，随着潜在井深度的减小，逃逸风的星系比例增加。我们进一步研究流出气体的物理性质，发现流出气体衰减增强的证据，这可能是由于富含金属的风，以及与银河盘中的气体相比更高的激发。鉴于以前的大多数研究都集中在具有更高恒星形成率和/或更明亮的活动星系核的更极端的系统上，我们的研究提供了低红移宇宙中“典型”星系内非引力气体运动的独特观点，
