Abstract:
We use the Hyper Suprime-Cam Subaru Strategic Program S19A shape
catalog to construct weak lensing shear-selected cluster samples. From
aperture mass maps covering ∼510deg2 created using a truncated
Gaussian filter, we construct a catalog of 187 shear-selected clusters
that correspond to mass map peaks with signal-to-noise ratio larger
than 4.7. Most of the shear-selected clusters have counterparts in
optically selected clusters, from which we estimate the purity of the
catalog to be higher than 95%. The sample can be expanded to 418
shear-selected clusters with the same signal-to-noise ratio cut by
optimizing the shape of the filter function and by combining weak
lensing mass maps created with several different background galaxy
selections. We argue that dilution and obscuration effects of cluster
member galaxies can be mitigated by using background source galaxy
samples and adopting a filter function with its inner boundary larger
than about 2'. The large samples of shear-selected clusters that are
selected without relying on any baryonic tracer are useful for
detailed studies of cluster astrophysics and cosmology.
Description:
We present updated catalogs of weak lensing shear-selected clusters
from the latest HSC-SSP S19A shape catalog covering ∼433deg2 (X. Li
et al. in preparation). We construct catalogs using three different
approaches adopting different shapes of filters. We also assign
redshifts of individual clusters by cross-matching the shear-selected
clusters with optically selected clusters.
