验证亚毫米星系是引力透镜需要花费大量时间和高分辨率天文台进行观测。在这里,我们的目标是通过与光学(SDSS)和近红外(VIKING)调查的交叉比较,加强赫歇尔亮源(草本)中引力透镜的证据,以寻找前景透镜星系候选者。对最亮的草本源的分辨率观测已经表明,大多数草本源是透镜状的,一个星系演化模型预测,大约76%的草本源是透镜状的,尽管通过SDSS调查,我们只能识别25%的源可能的前景透镜。然而,通过近红外VIKING调查,我们能够识别57%的源可能的前景透镜,我们估计82%的HerBS源在VIKING图像上有透镜,即使我们不能在每种情况下识别透镜。我们发现透镜和赫歇尔源之间的角偏移比预期的要大,如果透镜是由单个星系完成的。我们还发现,透镜状草本源的比例随着500微米通量密度的降低而下降,这是星系演化模型所期望的。最后,我们将统计维京交叉识别应用到整个赫歇尔-阿特拉斯星表中,我们也发现透镜源的数量随着500微米通量密度的降低而减少。
Verifying that sub-mm galaxies are gravitationally lensed requires time-expensive observations with oversubscribed high-resolution observatories. Here, we aim to strengthen the evidence of gravitational lensing within theHerschelBright Sources (HerBS) by cross-comparing their positions to optical (SDSS) and near-infrared (VIKING) surveys, in order to search for the foreground lensing galaxy candidates. Resolved observations of the brightest HerBS sources have already shown that most are lensed, and a galaxy evolution model predicts that ∼76 per cent of the total HerBS sources are lensed, although with the SDSS survey we are only able to identify the likely foreground lenses for 25 per cent of the sources. With the near-infrared VIKING survey, however, we are able to identify the likely foreground lenses for 57 per cent of the sources, and we estimate that 82 per cent of the HerBS sources have lenses on the VIKING images even if we cannot identify the lens in every case. We find that the angular offsets between lens andHerschelsource are larger than that expected if the lensing is done by individual galaxies. We also find that the fraction of HerBS sources that are lensed falls with decreasing 500-micron flux density, which is expected from the galaxy evolution model. Finally, we apply our statistical VIKING cross-identification to the entireHerschel-ATLAS catalogue, where we also find that the number of lensed sources falls with decreasing 500-micron flux density.
