We analyze an extremely deep 450-$mu$m image ($1sigma=0.56$,mJy,beam$^{-1}$) of a $simeq 300$,arcmin$^{2}$ area in the CANDELS/COSMOS field as part of the SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES). We select a robust (signal-to-noise ratio $geqslant 4$) and flux-limited ($geqslant 4$,mJy) sample of 164 sub-millimeter galaxies (SMGs) at 450-$mu$m that have $K$-band counterparts in the COSMOS2015 catalog identified from radio or mid-infrared imaging. Utilizing this SMG sample and the 4705 $K$-band-selected non-SMGs that reside within the noise level $leqslant 1$,mJy,beam$^{-1}$ region of the 450-$mu$m image as a training set, we develop a machine-learning classifier using $K$-band magnitude and color-color pairs based on the thirteen-band photometry available in this field. We apply the trained machine-learning classifier to the wider COSMOS field (1.6,deg$^{2}$) using the same COSMOS2015 catalog and identify a sample of 6182 450-$mu$m SMG candidates with similar colors. The number density, radio and/or mid-infrared detection rates, redshift and stellar mass distributions, and the stacked 450-$mu$m fluxes of these SMG candidates, from the S2COSMOS observations of the wide field, agree with the measurements made in the much smaller CANDELS field, supporting the effectiveness of the classifier. Using this 450-$mu$m SMG candidate sample, we measure the two-point autocorrelation functions from $z=3$ down to $z=0.5$. We find that the 450-$mu$m SMG candidates reside in halos with masses of $simeq (2.0pm0.5) times10^{13},h^{-1},rm M_{odot}$ across this redshift range. We do not find evidence of downsizing that has been suggested by other recent observational studies.
We construct a SCUBA-2 450-$mu$m map in the COSMOS field that covers an area of 300 arcmin$^{2}$ and reaches a 1$sigma$ noise level of 0.65 mJy in the deepest region. We extract 256 sources detected at 450 $mu$m with signal-to-noise ratio $>$ 4.0 and
The SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES) is a three-year JCMT Large Program aiming at reaching the 450 $mu$m confusion limit in the COSMOS-CANDELS region, to study a representative sample of the high-redshift far-infrared galaxy population
We present structural parameters and morphological properties of faint 450-um selected submillimeter galaxies (SMGs) from the JCMT Large Program, STUDIES, in the COSMOS-CANDELS region. Their properties are compared to an 850um selected and a matched
We investigate the multi-wavelength properties of a sample of 450-mu m selected sources from the SCUBA-2 Cosmology Legacy Survey (S2CLS). A total of 69 sources were identified above 4sigma in deep SCUBA-2 450-mu m observations overlapping the UDS and
We present a method of selection of 24~$mu$m galaxies from the AKARI North Ecliptic Pole (NEP) Deep Field down to $150 mbox{ }mu$Jy and measurements of their two-point correlation function. We aim to associate various 24 $mu$m selected galaxy populat
