Abstract

The DES-SN Program was a 5yr rolling search using the 570 Megapixel Dark Energy Camera (DECam; Flaugher et al. 2015AJ....150..150F) on the 4-m Blanco telescope at the Cerro Tololo Inter-American Observatory (CTIO), giving a 2.7deg2 field of view. DES-SN observed two 'deep' fields and eight 'shallow' fields in griz filters approximately every 7d, to single-visit depths of ~24.5 and ~23.5mag, respectively.

Transient events were detected using a difference-imaging pipeline (Kessler et al. 2015AJ....150..172K), with machine-learning algorithms used to remove spurious candidates (Goldstein et al. 2015AJ....150...82G). During the first 3yr, 251 SNe Ia were spectroscopically classified. Quality cuts, based on the light-curve coverage, are applied to the sample (see Brout et al. 2019ApJ...874..150B, Cat. J/ApJ/874/150 for details), which removes 45 SNe Ia. This leaves 206 SNe Ia in the fiducial DES sample.

Photometric data for the host galaxies of the DES3YR cosmology analysis (Brout et al. 2019ApJ...874..150B, Cat. J/ApJ/874/150) were determined from the DES SVA1-GOLD catalogue. This catalogue has 10σ limiting magnitudes of (g, r, i, z) = (24.0, 23.8, 23.0, 22.3). It was constructed from DES Science Verification data collected prior to the DES-SN data used in the DES3YR sample. In this paper, we upgrade from the DES SVA1-GOLD catalogue and instead determine photometric properties of the DES SNe Ia host galaxies from DES deep stack photometry (Wiseman et al. 2020MNRAS.495.4040W) utilizing images from all 5yr of DES-SN.
