摘要:

在AMIGA项目的背景下,我们使用法布里-珀罗观测来研究孤立星系CIG 0314中电离气体的动力学。从Halpha观测中,我们可以得到星系的速度场和自转曲线。为了了解气体的运动学,收集有利于或抑制恒星形成的机制的线索,特别是沿着酒吧的速度场的详细分析。可见光和暗物质的含量可以达到,以及估计星系的质量。

英文摘要:

In the context of the AMIGA project, we used Fabry-Perot observations in order to study the dynamics of the ionised gas in the isolated galaxy CIG 0314. From the Halpha observations, we could obtain the velocity field and rotation curve of the galaxy. A detail analysis of the velocity field is done in order to understand the kinematics of the gas to gather clues on the mechanisms which favour or inhibit star formation, in particular along the bar. The visible and dark matter content can be reached, as well as an estimation of the mass of the galaxy.
