Fabry-Perot干涉术与螺旋半导体动力学
Fabry-Perot Interferometry and Dynamics of Spiral Galaxies
摘要：
我们提出了近螺旋星系的发射线分布和运动学的二维Febry-Perot观测。我们已经开发并展示了一些具有普遍适用性的分析工具的实用性，但到目前为止，我们只应用于一个星系（M 74，Fathi等2007）。在这个星系中，我们发现了由m=2扰动引起的径向运动的运动学特征。这种扰动很可能是造成形成核环和内部快速旋转盘状结构的物质流入的原因。而后者则有助于建立一个伪膨胀。在本系列的第二篇论文中，我们将运用运动学分析工具对加拿大-法国-夏威夷望远镜的FaNTOmM法布里-珀罗光谱仪观测到的9个晚型螺旋星系样本进行分析。
英文摘要：
We present two-dimensional Febry-Perot observations of emission-line distribution and kinematics in nearly spiral galaxies. We have developed and demonstrated the utility of a number of analysis tools which have general applicability, but which we have, so far, applied to only one galaxy (M 74, Fathi et al. 2007). In this galaxy, we have found kinematic signatures of radial motions caused by an m=2 perturbation. Such a perturbation may well be responsible for the inflow of material forming the nuclear ring and the inner rapidly rotating disc-like structure. The latter, in turn, could help build a pseudo-bulge. In the second paper in this series, we will apply the kinematic analysis tools to a sample of 9 late-type spiral galaxies observed with the FaNTOmM Fabry-Perot spectrometer at the Canada-France-Hawaii telescope.
