In this work, we present a new catalogue of >40000 ionised nebulae distributed across the 19 galaxies observed by the PHANGS-MUSE survey. The nebulae have been classified using a new model-comparison-based algorithm that exploits the odds ratio principle to assign a probabilistic classification to each nebula in the sample. The resulting catalogue is the largest catalogue containing complete spectral and spatial information for a variety of ionised nebulae available so far in the literature. We developed this new algorithm to address some of the limitations of the traditional classification criteria, such as their binarity, the sharpness of the involved limits, and the limited amount of data they rely on for the classification. The analysis of the catalogue shows that the algorithm performs well when selecting H II regions. We can recover their luminosity function, and its properties are in line with what is available in the literature. We also identify a rather significant population of shock-ionised regions (mostly composed of supernova remnants), an order of magnitude larger than any other homogeneous catalogue of supernova remnants currently available in the literature. The number of supernova remnants we identify per galaxy is in line with results in our Galaxy and other very nearby sources. However, limitations in the source detection algorithm result in an incomplete sample of planetary nebulae, even though their classification seems robust. Finally, we demonstrate how applying a correction for the contribution of the diffuse ionised gas to the nebulae's spectra is essential to obtain a robust classification of the objects and how a correct measurement of the extinction using DIG-corrected line fluxes prompts the use of a higher theoretical Ha/Hb ratio (3.03) than what is commonly used when recovering the E(B-V) via the Balmer decrement technique in massive star-forming galaxies.

Dissecting the active galactic nucleus in Circinus IV. MUSE NFM observations unveil a tuning-fork ionised gas morphology
我们目前的电离气体外流的形态在Circinus星系使用窄场模式(NFM)的MUSE仪器上的甚大望远镜(VLT)。NFM观测提供了$\sim$ 0.1”的空间分辨率,对应于$\sim$ 2 pc的物理尺度,这是在光学波长中使用地面AO辅助观测可实现的最高空间分辨率之一。MUSE的观测揭示了一个平行的云团流出轮廓,起源于活动星系核附近,并在西北方向延伸到1.5”($\sim$ 30 pc)。准直的结构然后分裂成两个细丝,使整个流出的气体呈“音叉”形态。这些结构在较低空间分辨率的MUSE宽场模式数据中仍然未被检测到。我们解释的起源,这种音叉结构的相互作用的流出物与一个致密的团块在星际介质(ISM)的流出向外传播。准直结构本身的起源可能来自小尺度上的喷流-ISM相互作用。这些观测结果也为先前在圆规星系中观测到的千秒差距尺度的电离气体细丝的起源提供了证据。我们发现10 $^{-2}$ M $_{\odot}$ yr $^{-1}$和10 $^{-4}$ M $_{\odot}$ yr $^{-1}$的瞬时和时间平均质量流出率。基于文献中报道的圆规星系的恒星形成率,预计观察到的电离流出物不会在NFM数据探测的$\sim$ 100 pc尺度内调节恒星形成。

Stellar feedback in M83 as observed with MUSE -- I. Overview, an unprecedented view of the stellar and gas kinematics and evidence of outflowing gas
我们提出了一个大的VLT/MUSE马赛克(3.8 × 3.8千秒差距)附近的旋涡星系M83,空间分辨率约20秒差距。我们得到了恒星和电离气体的运动学,并与ALMA CO(2-1)的分子气体运动学进行了比较。我们将电离气体分为HII区和扩散电离气体(DIG),并确定了来自DIG的Ha光度分数(f_DIG)。我们观察到,恒星和气体跟踪银河系盘旋转,以及快速旋转的核组件,可能连接到长期的过程驱动的银河酒吧。在气体运动学中,我们观察到原子核以东的气流,相对于圆盘发生了红移。该流被一个扩展的电离气体区域所包围,该电离气体区域具有增强的速度分散和高电离状态,这在很大程度上与被慢冲击电离一致。我们解释这一功能的叠加盘和平面外层的DIG,或作为一个酒吧驱动的冲击气体流入。一个双高斯分量拟合的Ha线也揭示了存在一个核的双锥结构,其对称轴是垂直于酒吧。这两个锥沿着视线出现蓝移和红移,并突出具有Ha发射,其与盘的分离高达200 km s-1,以及高速色散~80-200 km s-1。在锥体的远端,我们观察到气体与被冲击电离一致。这些特征以前从未在M83中观察到过;我们假设它们是在追踪一个恒星暴驱动的外流,冲击周围的ISM。最后,我们在我们的视野中获得f_DIG ~ 13%。我们检查发射的HII地区和DIG的“BPT”图,发现在HII地区的光电离占99.8%的哈通量,而DIG有混合贡献的光电离(94.9%…
