摘要

We discuss the submillimeter properties of extremely red objects (EROs) in the two Canada-UK Deep Submillimeter Survey (CUDSS) fields. We measure the mean submillimeter flux of the ERO population (to K' 20.7) and find 0.40 ± 0.07 mJy for EROs selected by (I-K) 4.0 and 0.56 ± 0.09 mJy for EROs selected by (R-K) 5.3, but these measurements are dominated by discrete, bright submillimeter sources. We estimate that EROs produce 7%-11% of the far-infrared background at 850 μm. This is substantially less than a previous measurement by Wehner, Barger, & Kneib, and we discuss possible reasons for this discrepancy. We show that ERO counterparts to bright submillimeter sources lie within the starburst region of the near-infrared color-color plot of Pozzetti & Mannucci. Finally, we claim that pairs or small groups of EROs with separations of 10'' often mark regions of strong submillimeter flux.
