5 Feb 2020 | | Abstract: | We report the largest sample of candidate strong gravitational lenses
belonging to the Survey of Gravitationally-lensed Objects in HSC Imaging for
group-to-cluster scale (SuGOHI-c) systems. These candidates are compiled from
the S18A data release of the Hyper Suprime-Cam Subaru Strategic Program
(HSC-SSP) Survey. We visually inspect $sim39,500$ galaxy clusters, selected
from several catalogs, overlapping with the Wide, Deep, and UltraDeep fields,
spanning the cluster redshift range $0.05<z_{cl}<1.38$. We discover 641
candidate lens systems, of which 537 are new. From the full sample, 47 are
almost certainly bonafide lenses, 181 of them are highly probable lenses and
413 are possible lens systems. Additionally, we present 131 lens candidates at
galaxy-scale serendipitously discovered during the inspection. We obtained
spectroscopic follow-up of 10 candidates using the X-shooter. With this
follow-up, we confirm 8 systems as strong gravitational lenses. Out of the
remaining two, the lensed sources of one of them was too faint to detect any
emission, and the source in the second system has redshift close to the lens
but other additional arcs in this system are yet to be tested
spectroscopically. Since the HSC-SSP is an ongoing survey, we expect to find
$sim600$ definite or probable lenses using this procedure and more if combined
with other lens finding methods. | | Source: | arXiv, 2002.1611 | | Services: | Forum | Review | PDF | Favorites | |
