论文摘要
我们在Hyper Suprime-CAM Subaru战略计划（HSC SSP）的数据发布4中对Galaxy尺度强引力透镜系统进行了搜索，该数据包括由S21A学期的数据组成。我们从Baryon振荡光谱调查（BOSS）样品中选择103191发光的红色星系，这些样品具有来自HSC SSP的深层多播成像，并使用Yattalens算法自动识别具有蓝色ARC类似特征的镜头候选者。候选人根据镜头的可能性在视觉上检查和分级。我们发现8个确定的镜片，28个可能的镜头和138个可能的镜片。新镜头候选物通常在$ 0.3 \ Lesssim z _ {\ Mathrm {l}}} \ Lessim 0.9 $的范围内具有镜头红移，这是一个关键的中间红移范围，以研究星系结构的演变。随访光谱法将确认这些新镜头并测量源红移，以实现详细的透镜建模。
We conduct a search for galaxy-scale strong gravitational lens systems in Data Release 4 of the Hyper Suprime-Cam Subaru Strategic Program (HSC SSP), consisting of data taken up to the S21A semester. We select 103191 luminous red galaxies from the Baryon Oscillation Spectroscopic Survey (BOSS) sample that have deep multiband imaging from the HSC SSP and use the YattaLens algorithm to automatically identify lens candidates with blue arc-like features. The candidates are visually inspected and graded based on their likelihood of being a lens. We find 8 definite lenses, 28 probable lenses, and 138 possible lenses. The new lens candidates generally have lens redshifts in the range $0.3 \lesssim z_{\mathrm{L}} \lesssim 0.9$, a key intermediate redshift range to study the evolution of galaxy structure. Follow-up spectroscopy will confirm these new lenses and measure source redshifts to enable detailed lens modeling.
