摘要:

星系的演化很大程度上受到它们之间相互作用的影响。作为研究相互作用星系计划的一部分,我们测量并模拟了从紫外(UV)到远红外(FIR)的光谱能量分布(SED)。我们描述了这些SED对恒星形成历史的约束,以及在相互作用序列中看到的变化,我们比较了应用于数据的不同恒星形成率处方的结果。样本本身是基于斯皮策相互作用星系巡天(SIGS)的50个系统中的111个星系,该项目旨在探测红外星系相互作用参数的范围。我们的SED将斯皮策的结果与其他任务的多波长数据相结合,特别是GALEX和Herschel。这里给出的子集是FIR Herschel观测目前公开可用的样本。

英文摘要:

The evolution of galaxies is greatly influenced by their interactions. As part of a program to study interacting galaxies, we have measured and modeled the spectral energy distri- butions (SEDs) from the ultraviolet (UV) to the far-infrared (FIR). We describe the constraints imposed on star formation histories by these SEDs, and the variations therein seen across the interaction sequence, and we compare the results of different star formation rate prescriptions applied to the data. The sample itself is based on the Spitzer Interacting Galaxy Survey (SIGS) of 111 galaxies in 50 systems, a project designed to probe a range of galaxy interaction parameters in the infrared. Our SEDs combine the Spitzer results with multiwavelength data from other missions, in particular GALEX and Herschel. The subset presented here is the sample for which FIR Herschel observations are currently publicly available.
