The aim of this project is to analyse gas kinematics in centres of galaxies observed with integral-field spectrographs MUSE and SINFONI. The observed gas velocity fields will be interpreted in terms of the existing gas flow models, and correlations between particular types of flows and the galaxy's activity and its underlying gravitational potential will be explored. The expected outcome is identification of nuclear components in galaxies from patterns in gas flow imposed by them, and establishing types of gas flows that are capable of feeding active galactic nuclei. We are in possession of the data for the centres of 23 nearby galaxies, which include MUSE and SINFONI integral-field spectra with accompanying HST imaging. The size of this sample is sufficient for studying the relation of gas flows to the nuclear activity and to the nuclear components.

该项目的目的是分析用积分场摄谱仪MUSE和SINFONI观测到的星系中心的气体运动学。观测到的气体速度场将根据现有的气体流动模型进行解释，并将探讨特定类型的流动与星系活动及其潜在引力势之间的相关性。预期的结果是从星系中的气体流动模式中识别出星系中的核成分，并确定能够为活动星系核提供能量的气体流动类型。我们拥有23个邻近星系中心的数据，其中包括MUSE和SINFONI积分场光谱以及伴随的HST成像。这个样品的大小足以研究气体流量与核活动和核成分的关系。
