The Spitzer Data Fusion: Contents, Construction and Applications to Galaxy Evolution Studies
Abstract
We present the Spitzer Data Fusion, a database incorporating far-ultraviolet to far-infrared flux measurements as well as photometric and spectroscopic redshifts for 4.4 million IRAC-selected sources detected over 8 extragalactic fields covering 65 deg$^2$ observed by Spitzer in all IRAC and MIPS bands during its cryogenic mission. Deeper Spitzer observations carried out during its warm mission over 5 sub-fields as part of the SERVS project are also presented and analysed in a similar fashion, detecting 2.8 million IRAC-selected sources over 18 deg$^2$ and merging them with multi-wavelength catalogues within the SERVS Data Fusion. When combined with Herschel SPIRE surveys and radio continuum observations over the same fields, the Spitzer Data Fusion and the SERVS Data Fusion provide an invaluable resource for multi-wavelength galaxy formation and evolution studies at infrared/millimetre/radio wavelengths. The catalogues and their future updates are publicly available at http://www.mattiavaccari.net/df/ and on Zenodo at https://zenodo.org/record/6120914#.YjsnszdByu4
