英文摘要

We have collected almost all published dust obscured galaxies (DOGs) with the certain coordinate in the literature (817 DOGs in total) to investigate their infrared properties by using 2MASS (and other observations in the JHK bands), WISE, IRAS and Herschel data in this paper. Our study shows that objects with different types have different presentations for the relations between the redshift and infrared colors. It is also found that in the near infrared two-color diagram, DOGs are distributed across the blackbody line and the power law line indicative of the thermal emission from the stellar component and the star formation for some objects, and the AGN dominated for other objects in the near infrared. However, in the two-color diagrams with longer wavelengths the majority of DOGs are distributed around the power law line indicative of the central AGN dominated in the midinfrared, far infrared, and submillimeter regions. We also compared the infrared color propertes between DOGs and ULIRGs. It is found that, statistically, ULIRGs have redder colors than that for DOGs in the near and midinfrared region while compared with DOGs, ULIRGs are more near the blackbody line indicative of the star formation dominated in far infrared.
