Deep Hyper Suprime-Cam Images and a Forced Photometry Catalog in W-CDF-S

Astrophysics of Galaxies 2018-12-19 v1

Abstract

The Wide Chandra Deep Field-South (W-CDF-S) field is one of the SERVS fields with extensive multiwavelength datasets, which can provide insights into the nature and properties of objects in this field. However, the public optical data from DES (grizygrizy to mAB21.424.3m\rm_{AB} \approx 21.4-24.3) are not sufficiently deep to match well the NIR data from VIDEO (ZYJHKsZYJHK_s to mAB23.525.7m\rm_{AB} \approx 23.5-25.7), which limits the investigation of fainter objects at higher redshifts. Here, we present an optical catalog of \approx 2,000,000 objects in W-CDF-S utilizing archival Hyper Suprime-Cam observations in the g,r,i,zg,r,i,z bands covering 5.7 deg2\approx5.7 \rm~deg^2. The estimated depth is \approx 25.9 for gg-band, 25.6 for rr-band, 25.8 for ii-band, and 25.2 for zz-band, which is deep enough to complement the NIR data, and will benefit AGN/galaxy studies in W-CDF-S in the future.
