The goal of this collaborative program is to use the spectral energy distributions (SEDs) and morphologies of infrared luminous galaxies to study galaxy formation and evolution. The SED will allow inference of the physical conditions in a galaxy such as the role of an active galactic nucleus in heating the dust. Together with the observed morphology, the program will determine the mode of star formation, and whether it occurs primarily through galaxy mergers or by continuous gas accretion onto the galaxy from the intergalactic medium.Broader impacts of the work include training of undergraduate students, a publicly released SED library, and a publicly released galaxy evolution modeling code.

该协作计划的目标是使用光谱能量分布（SED）和红外发光星系的形态来研究星系形成和进化。 SED将允许在星系中推断物理条件，例如活性银河核在加热灰尘中的作用。 该程序将与观察到的形态一起确定恒星形成的模式，以及它主要是通过星系合并或连续燃气从层间介质到银河系的连续吸收。
