Deep Extragalactic VIsible Legacy Survey (DEVILS): consistent multiwavelength photometry for the DEVILS regions (COSMOS, XMMLSS, and ECDFS)

Abstract

The Deep Extragalactic VIsible Legacy Survey (DEVILS) is an ongoing high-completeness, deep spectroscopic survey of ∼60 000 galaxies to Y < 21.2 mag, over ∼6 deg2 in three well-studied deep extragalactic fields: D10 (COSMOS), D02 (XMM-LSS) and D03 (ECDFS). Numerous DEVILS projects all require consistent, uniformly-derived and state-of-the-art photometric data with which to measure galaxy properties. Existing photometric catalogues in these regions either use varied photometric measurement techniques for different facilities/wavelengths leading to inconsistencies, older imaging data and/or rely on source detection and photometry techniques with known problems. Here we use the ProFound image analysis package and state-of-the-art imaging datasets (including Subaru-HSC, VST-VOICE, VISTA-VIDEO and UltraVISTA-DR4) to derive matched-source photometry in 22 bands from the FUV to 500 μm. This photometry is found to be consistent, or better, in colour-analysis to previous approaches using fixed-size apertures (which are specifically tuned to derive colours), but produces superior total source photometry, essential for the derivation of stellar masses, star-formation rates, star-formation histories, etc. Our photometric catalogue is described in detail and, after internal DEVILS team projects, will be publicly released for use by the broader scientific community.

“…zCOSMOS;Lilly et al 2009) and as such currently has the highest spectroscopic completeness. We use the new DEVILS photometry catalogue as described in depth by Davies et al (2021) which uses the P F source extraction code (Robotham et al 2018) to detect sources and measure source photometry consistently in 22 bands spanning the FUV-FIR (1500Å-500 𝜇m). For D10 we use imaging in the GALEX FUV NUV (Zamojski et al 2007), CFHT u (Capak et al 2007), Subaru HSC griz (Aihara et al 2019), VISTA YJHK 𝑠 (McCracken et al 2012), Spitzer IRAC1 IRAC2 IRAC3 IRAC4 MIPS24 MIPS70 (Sanders et al 2007;Laigle et al 2016), and Herschel P100 P160 S250 S350 S500 (Lutz et al 2011;Oliver et al 2012) bands.…”
