Abstract:
In this paper we present a simple color-magnitude selection and obtain
a large sample of 33,893 massive quiescent galaxies at intermediate
redshifts (1<z<1.5). We choose the longest wavelength available in the
Hyper-Supreme-Cam (HSC) deep survey, the Y band and i-Y color, to
select the 4000Å Balmer jump in passive galaxies to the highest
redshift possible within the survey. With the rich multiwavelength
data in the HSC deep fields, we then confirm that the selected
galaxies are in the targeted redshift range of 1<z<1.5, lie in the
passive region of the UVJ diagram, and have high stellar masses at
log(M*/M☉)>10.5, with a median of log(M*/M☉)=11.0. A
small fraction of our galaxies is also covered by the HST CANDELS.
Morphological analysis in the observed H band shows that the majority
of this subsample are early-type galaxies. As massive early-type
galaxies trace the high-density regions in the large-scale structure
in the universe, our study provides a quick and simple way to obtain a
statistically significant sample of massive galaxies in a relatively
narrow redshift range. Our sample is 7-20x larger at the massive end
(log(M*/M☉)>10.5) than any existing samples obtained in
previous surveys. This is a pioneer study, and the technique
introduced here can be applied to a future wide-field survey to study
large-scale structure and to identify high-density regions and
clusters.
Description:
In this paper, we present a single color selection of passive galaxies
at z∼1.2, from the recent deep survey in the Hyper Suprime-Cam
Subaru Strategic Program (HSC-SSP; Aihara+ 2018PASJ...70S...8A 2018PASJ...70S...8A &
2019PASJ...71..114A 2019PASJ...71..114A).
The paper uses cosmological parameters h=H0[km/s/Mpc]/100=0.70,
ΩΛ=0.7, and ΩM=0.3.
