Integral Field Spectroscopy of low-z Luminous Infrared Galaxies

最近的斯皮策宇宙学巡天已经证明，大多数z < 1的红外选择星系都属于LIRG类（LIR = L [9- 1000 ^m] = 1011 - 1012 LG），并且LIRG对1 < z < 2的红外星系群有着重要的贡献。这次运行是一个最大的项目的一部分，其中一个代表性的低z（z < 0.07）LIRG样品将被观察与PMAS积分场光谱仪。它的目的是涵盖不同的形态（孤立星系，相互作用的星系和合并）和一系列的红外光度。这是第一次系统地研究低z激光陀螺的性质，特别是，我们将研究恒星群体的二维性质和系统的运动学。该研究将是理解红外选择高z星系星族的关键。

Recent spitzer cosmological surveys have demostrated that the majority of IR-selected galaxies at z < 1 are in the LIRG class (LIR = L [9-lOOO^m] = 1011 - 1012 LG) and that LIRGs make a significant contribution to the IR galaxy population at 1 < z < 2. This run is part of a biggest Project where a representative sample of low-z (z < 0.07) LIRGs are going to be observed with the PMAS integral field spectrograph. It is intended to cover the different morphologies (isolated galaxies, interacting galaxies and mergers) and a range of IR luminosities. This is the first systematic study of the properties fo a sample of low-z LIRGs, In particular, we will study the 2D properties of the stellar populations and the kinematics of the systems. This study will be the key to understand the Population of IR-selected high-z galaxies.
