局部亮红外星系的Spitzer/IRS制图

Spitzer/IRS Mapping of Local Luminous Infrared Galaxies

Miguel Pereira-Santaella, Almudena Alonso-Herrero, George H. Rieke, Luis Colina

摘要:

我们目前的结果,我们的程序斯皮策/IRS映射的本地发光红外Galeries(LIRGs)。这些地图覆盖了星系中心的20“x20”或30“x30”区域,并使用了所有四个IRS模块来覆盖整个5-38微米的光谱范围。我们构建了主要中红外发射线、连续谱和多环芳烃特征的光谱图,并提取了每个星系感兴趣区域的一维光谱。最终的目标是充分表征本地LIRGs的中红外特性,作为了解其更远对应物的第一步。

英文摘要:

We present results of our program Spitzer/IRS Mapping of local Luminous Infrared Galaxies (LIRGs). The maps cover the central 20"x20" or 30"x 30" regions of the galaxies, and use all four IRS modules to cover the full 5-38 microns spectral range. We have built spectral maps of the main mid-IR emission lines, continuum and PAH features, and extracted 1D spectra for regions of interest in each galaxy. The final goal is to fully characterize the mid-IR properties of local LIRGs as a first step to understanding their more distant counterparts.
