狗的谱系(Dust-Obscured Galeries)

The Pedigrees of DOGs (Dust-Obscured Galaxies)

Arjun Dey, the NDWFS/MIPS Collaboration

摘要:

R-[24]>14织女星等的简单中红外至光学颜色标准导致了大约一半的红移2超亮红外星系(ULIRG)种群的稳健选择。这些“尘埃遮蔽的星系”(DOG)有许多特性,表明它们是处于富气合并和类星体之间过渡阶段的系统的良好候选者。

英文摘要:

A simple mid-infrared-to-optical color criterion of R-[24]>14 Vega mag results in a robust selection of approximately half of the redshift 2 ultraluminous infrared galaxy (ULIRG) population. These `Dust-Obscured Galaxies', or DOGs, have many properties that suggest that they are good candidates for systems in a transition phase between gas-rich mergers and QSOs.
