SCUBA-2 850um survey of the JWST-TDF & 3GHz VLA obs.
Listed in IVOA Registry (Virtual Observatory)
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.
Description
Here, we describe our James Clerk Maxwell Telescope SCUBA-2 850um 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 3GHz observations of the field.
These observations were obtained to aid JWST's study of dust-obscured galaxies that contribute significantly to cosmic star formation at high redshifts. Our deep 850um map covers the JWST-TDF at a noise level of {sigma}_850um_=1.0mJy/beam, detecting 83/31 sources in the main/supplementary signal-to-noise ratio (S/N>4 / S/N=3.5-4) sample, respectively. The 3GHz observations cover a 24' diameter field with a 1{sigma} noise of 1uJy/beam at a 0.7" FWHM.

We identified eighty-five 3GHz counterparts to sixty-six 850um sources and then matched these with multiwavelength data from the optical to the mid-infrared wave bands. We performed spectral energy distribution fitting for 61 submillimeter galaxies (SMGs) matched with optical/near-infrared data, and found that SMGs at S/N>4 have a median value of z_phot_=2.22+/-0.12, star formation rates of 300+/-40M_{sun}_/yr (Chabrier initial mass function), and typical cold dust masses of 5.9+/-0.7x10^8^M_{sun}_, in line with bright SMGs from other surveys.
The large cold dust masses indicate correspondingly large cool gas masses, which we suggest are a key factor necessary to drive the high star formation rates seen in this population.
