论文摘要
我们在分辨率为0.35至3个弧形的34个候选高红移尘尘形成星系（DSFGS）的样本中的分辨率上进行了SMA观察。这些来源是从爱马仕Herschel调查目录中选择的，使SEDS从250升至350 $μ$ m，这是500名人口。我们检测到其中24个来源的对应物，其中四个具有两个对应物。我们得出的结论是，其余的十种缺乏被检测到的对应物的来源可能具有三个或更多相关的来源，这些来源融合在一起以产生观察到的Herschel源。我们研究了镜头的作用，该角色预计将占主导地位（F500 $> 6000万美元）的一半样本。我们发现，尽管镜头发挥作用，但至少有35％的亮源可能是多种来源，而不是镜头的结果。在轻率的通量下，我们发现混合速率可与预测的40％相当或大于预测的40％。我们确定了样本中非元素源的Far-Ir灯光和星形形成率，得出的结论是，在没有强镜的情况下，我们的500名速度是非常发光的系统，具有L $ _ {fir}> 10^{13} {13} $ l $ _ {\ odot} $ {\ odot} $ and Star Formation and star Formation and Star Formation and $> 1000 $ M $ m $ m $ m $ _ _}
We present SMA observations at resolutions from 0.35 to 3 arcseconds of a sample of 34 candidate high redshift dusty star forming galaxies (DSFGs). These sources were selected from the HerMES Herschel survey catalogues to have SEDs rising from 250 to 350 to 500$μ$m, a population termed 500-risers. We detect counterparts to 24 of these sources, with four having two counterparts. We conclude that the remaining ten sources that lack detected counterparts are likely to have three or more associated sources which blend together to produce the observed Herschel source. We examine the role of lensing, which is predicted to dominate the brightest (F500 $>$ 60mJy) half of our sample. We find that while lensing plays a role, at least 35% of the bright sources are likely to be multiple sources rather than the result of lensing. At fainter fluxes we find a blending rate comparable to, or greater than, the predicted 40%. We determine far-IR luminosities and star formation rates for the non-multiple sources in our sample and conclude that, in the absence of strong lensing, our 500-risers are very luminous systems with L$_{FIR} > 10^{13}$L$_{\odot}$ and star formation rates $> 1000$M$_{\odot}$/yr.
