| dc.description | We report on interferometric observations at 1.3 mm at 2”−3” resolution using the Combined Array for Research in Millimeter-wave Astronomy (CARMA). We identify multi-wavelength counterparts of three submillimeter galaxies (SMGs; F1mm> 5.5 mJy) in the COSMOS field, initially detected with MAMBO and AzTEC bolometers at low, ~ 10” − 30”, resolution. All three sources – AzTEC/C1, Cosbo-3 and Cosbo-8 – are identified to coincide with positions of 20 cm radio sources. Cosbo-3, however, is not associated with the most likely radio counterpart, closest to the MAMBO source position, but that further away from it. This illustrates the need for intermediate-resolution (~ 2”) mm-observations to identify the correct counterparts of single-dish detected SMGs. All of our three sources become prominent only at NIR wavelengths, and their mm-to-radio flux based redshifts suggest that they lie at redshifts z ≳ 2. As a proof of concept, we show that photometric redshifts can be well determined for SMGs, and we find photometric-redshifts of 5.6±1.2, 1.9+0.9−0.5, and ~ 4 for AzTEC/C1, Cosbo-3, and Cosbo-8, respectively. Using these we infer that these galaxies have radio-based star formation rates of ≳ 1000 M⊙yr ⁻¹, and IR luminosities of ~10¹³ L⊙ consistent with properties of high-redshift SMGs. In summary, our sources reflect a variety of SMG properties in terms of redshift and clustering, consistent with the framework that SMGs are progenitors of z ~ 2 and today’s passive galaxies. | |
