CANDELS Multiwavelength catalogs: Source Identification and Photometry in the CANDELS UKIDSS Ultra-Deep Survey Field

TL;DR

This paper presents a comprehensive multiwavelength catalog for the UKIDSS UDS field, integrating data from various telescopes to facilitate galaxy and source analysis across ultraviolet to mid-infrared wavelengths.

Contribution

It provides the first extensive multiwavelength catalog for the UDS field, combining data from HST, CFHT, Subaru, VLT, UKIDSS, and Spitzer, with spectroscopic redshifts for a subset of sources.

Findings

Catalog contains 35,932 sources over 201.7 sq. arcmin.

Includes multiwavelength data from UV to mid-infrared.

Provides spectroscopic redshifts for 210 sources.

Abstract

We present the multiwavelength - ultraviolet to mid-infrared - catalog of the UKIDSS Ultra-Deep Survey (UDS) field observed as part of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS). Based on publicly available data, the catalog includes: the CANDELS data from the Hubble Space Telescope (near-infrared WFC3 F125W and F160W data and visible ACS F606W and F814W data), u-band data from CFHT/Megacam, B, V, Rc, i' and z' band data from Subaru/Suprime-Cam, Y and Ks band data from VLT/HAWK-I, J, H and K bands data from UKIDSS (Data Release 8), and Spitzer/IRAC data (3.6, 4.5 from SEDS, 5.8 and 8.0um from SpUDS). The present catalog is F160W-selected and contains 35932 sources over an area of 201.7 square arcmin and includes radio and X-ray detected sources and spectroscopic redshifts available for 210 sources.
