The JWST North Ecliptic Pole Time Domain Field (NEP-TDF): Results from HST, JWST, Chandra, and NuSTAR observations
Abstract
We present 11-filter imaging observations with HST and JWST within the JWST North Ecliptic Pole (NEP) Time Domain Field (TDF), taken as part of the multi-cycle "TREASUREHUNT" HST and "PEARLS" JWST GTO programs and spanning the 0.26 - 5 μm wavelength range (to a 5σ depth of mAB ~ 27 - 29 mag). The JWST NEP TDF is located within JWST's northern Continuous Viewing Zone at (RA,Dec)J2000 = (17:22:47.896, +65:49:21.54), and spans ~15 arcmin in diameter. This field is nearly fully covered by HST, while JWST sampled ~55 arcmin2 (divided over four distinct "spokes"). JWST can observe this clean extra-galactic deep survey field at arbitrary cadence or arbitrary orientation, and a wealth of ancillary observations from hard X-rays to long-wave radio already exists and continues to accumulate. Here we present a first rich harvest of transients and variable candidates discovered in the HST images, X-ray sources detected by Chandra and NuSTAR, as well as highlights from our first year of PEARLS NEP-TDF results, including the properties of radio sources and the search for high redshift galaxies and AGN in this field.
