TL;DR
This study presents deep submillimeter and radio observations of the JWST Time-Domain Field near the North Ecliptic Pole, identifying and characterizing dust-obscured galaxies to aid high-redshift star formation research.
Contribution
It provides the first comprehensive submillimeter and radio source catalog for the JWST-TDF, including multiwavelength data and physical properties of detected galaxies.
Findings
Detected 83/31 sources in submillimeter with S/N > 4 / 3.5-4.
Matched 85 radio counterparts to 66 submillimeter sources.
SMGs have median redshift ~2.22, high star formation rates, and large dust and gas masses.
Abstract
The James Webb Space Telescope Time-Domain Field (JWST-TDF) is an 14 diameter field near the North Ecliptic Pole that will be targeted by one of the JWST Guaranteed Time Observations programs. Here, we describe our James Clerk Maxwell Telescope SCUBA-2 850 m imaging of the JWST-TDF and present the submillimeter source catalog and properties. We also present a catalog of radio sources from Karl J. Jansky Very Large Array 3 GHz observations of the field. These observations were obtained to aid JWST's study of the dust-obscured galaxies that contribute significantly to the cosmic star formation at high redshifts. Our deep 850 m map covers the JWST TDF at a noise level of = 1.0 mJy beam, detecting 83/31 sources in the main/supplementary signal-to-noise ratio (S/N 4 / S/N = 3.5 - 4) sample respectively. The 3 GHz observations cover a 24…
