“…The X-ray data are from Chen et al (2018), the 0.36-4.5 μm data are from Hudelot et al (2012) and K.

“…Rich multiwavelength data sets (archival or planned) are available in all the DDFs. To name just a few, these include the XMM-Spitzer Extragalactic Representative Volume Survey (XMM-SERVS) 17 in X-rays (Chen et al 2018;Ni et al 2021a), the Spitzer DeepDrill survey in the infrared (Lacy et al 2021), and the MeerKAT International GHz Tiered Extragalactic Exploration survey in the radio (Jarvis et al 2016;Heywood et al 2022). The DDFs will be valuable for many kinds of studies involving time-domain astronomy, ultradeep imaging, or multiwavelength investigations.…”

W-CDF-S, ELAIS-S1, and XMM-LSS will be three Deep-Drilling Fields (DDFs) of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), but their extensive multiwavelength data have not been fully utilized as done in the COSMOS field, another LSST DDF. To prepare for future science, we fit source spectral energy distributions (SEDs) from X-ray to far-infrared in these three fields mainly to derive galaxy stellar masses and star formation rates. We use CIGALE v2022.0, a code that has been regularly developed and evaluated, for the SED fitting. Our catalog includes 0.8 million sources covering 4.9 deg2 in W-CDF-S, 0.8 million sources covering 3.4 deg2 in ELAIS-S1, and 1.2 million sources covering 4.9 deg2 in XMM-LSS. Besides fitting normal galaxies, we also select candidates that may host active galactic nuclei (AGNs) or are experiencing recent star formation variations and use models specifically designed for these sources to fit their SEDs; this increases the utility of our catalog for various projects in the future. We calibrate our measurements by comparison with those in well-studied smaller regions and briefly discuss the implications of our results. We also perform detailed tests of the completeness and purity of SED-selected AGNs. Our data can be retrieved from a public website.

“…We therefore chose NWAY (Salvato et al 2018; see Section 4 for a basic description ofNWAY) to match XMM-Newton sources with optical/near-IR (NIR) counterparts with priors as described in Section 4 within 10″, using an iterative method. In the NIR, we use Spitzer data from the DeepDrill data release (Lacy et al 2021) that includes the SERVS data (Mauduit et al 2012), and VISTA data from the VIDEO data release in 2020 (M. Jarvis et al 2021, private communication) for both the W-CDF-S and ELAIS-S1 fields. In the optical, we use HSC data from Ni et al (2019) for W-CDF-S and DES DR2 data (Abbott et al 2021) for ELAIS-S1 (see Table 1 for the survey descriptions).…”

We present the X-ray point-source catalogs in two of the XMM-Spitzer Extragalactic Representative Volume Survey (XMM-SERVS) fields, W-CDF-S (4.6 deg 2 ) and ELAIS-S1 (3.2 deg 2 ), aiming to fill the gap between deep pencil-beam X-ray surveys and shallow X-ray surveys over large areas. The W-CDF-S and ELAIS-S1 regions were targeted with 2.3 and 1.0 Ms of XMM-Newton observations, respectively; 1.8 and 0.9 Ms exposures remain after flare filtering. The survey in W-CDF-S has a flux limit of 1.0 × 10 −14 erg cm −2 s −1 over 90% of its area in the 0.5-10 keV band; 4053 sources are detected in total. The survey in ELAIS-S1 has a flux limit of 1.3 × 10 −14 erg cm −2 s −1 over 90% of its area in the 0.5-10 keV band; 2630 sources are detected in total. Reliable optical-to-IR multiwavelength counterpart candidates are identified for ≈89% of the sources in W-CDF-S and ≈87% of the sources in ELAIS-S1. A total of 3129 sources in W-CDF-S and 1957 sources in ELAIS-S1 are classified as active galactic nuclei (AGNs). We also provide photometric redshifts for X-ray sources; ≈84% of the 3319/2001 sources in W-CDF-S/ELAIS-S1 with optical-to-near-IR forced photometry available have either spectroscopic redshifts or high-quality photometric redshifts. The completion of the XMM-Newton observations in the W-CDF-S and ELAIS-S1 fields marks the end of the XMM-SERVS survey data gathering. The ≈12,000 pointlike X-ray sources detected in the whole ≈13 deg 2 XMM-SERVS survey will benefit future large-sample AGN studies.

“…In their analysis, Barmby et al (2008) inject artificial sources into the IRAC mosaics and derive completeness estimates based on their success in recovering these artificial sources. The validity of using these corrections a comparison of counts in these fields is discussed in Lacy et al (2021).…”

The luminosity function (LF) of active galactic nuclei (AGN) probes the history of supermassive black hole assembly and growth across cosmic time. To mitigate selection biases, we present a consistent analysis of the AGN LFs derived for both X-ray and mid-infrared (MIR) selected AGN in the XMM-Large Scale Structure (XMM-LSS) field. There are 4268 AGN used to construct the MIR luminosity function (IRLF) and 3427 AGN used to construct the X-ray luminosity function (XLF), providing the largest census of the AGN population out to z = 4 in both bands with significant reduction in uncertainties. We are able for the first time to see the knee of the IRLF at z > 2 and observe a flattening of the faint-end slope as redshift increases. The bolometric luminosity density, a proxy for the cosmic black hole accretion history, computed from our LFs shows a peak at z ≈ 2.25 consistent with recent estimates of the peak in the star formation rate density (SFRD). However, at earlier epochs, the AGN luminosity density is flatter than the SFRD. If confirmed, this result suggests that the build up of black hole mass outpaces the growth of stellar mass in high mass systems at z 2.5. This is consistent with observations of redshift z ∼ 6 quasars which lie above the local M − σ relationship. The luminosity density derived from the IRLF is higher than that from the XLF at all redshifts. This is consistent with the dominant role of obscured AGN activity in the cosmic growth of supermassive black holes.
