JWST NEP TDF NuSTAR and XMM-Newton survey

Listed in IVOA Registry (Virtual Observatory)

We present the second NuSTAR and XMM-Newton extragalactic survey of the JWST North Ecliptic Pole (NEP) Time-Domain Field (TDF).

Description

The first NuSTAR NEP-TDF survey (Zhao et al., 2021MNRAS.508.5176Z, Cat. J/MNRAS/508/5176) had 681ks total exposure time executed in NuSTAR cycle 5, in 2019 and 2020.

This second survey, acquired from 2020 to 2022 in cycle 6, adds 880ks of NuSTAR exposure time. The overall NuSTAR NEP-TDF survey is the most sensitive NuSTAR extragalactic survey to date, and a total of 60 sources were detected above the 95% reliability threshold. We constrain the hard X-ray number counts, logN-logS, down to 1.7x10^-14^erg/cm^2^/s at 8-24keV and detect an excess of hard X-ray sources at the faint end.

About 47% of the NuSTAR-detected sources are heavily obscured (N_H_>10^23^cm^-2^), and 18^+20^_-8_% of the NuSTAR-detected sources are Compton-thick (_H_N>10^24^cm^-2^). These fractions are consistent with those measured in other NuSTAR surveys. Four sources presented >2{sigma} variability in the 3-year survey.

In addition to NuSTAR, a total of 62ks of XMM-Newton observations were taken during NuSTAR cycle 6. The XMM-Newton observations provide soft X-ray (0.5-10keV) coverage in the same field and enable more robust identification of the visible and infrared counterparts of the NuSTAR-detected sources. A total of 286 soft X-ray sources were detected, out of which 214 XMM-Newton sources have secure counterparts from multiwavelength catalogs.
