Color (g − r)₀ and stellar surface mass density profiles of NGC 1052-DF2 using data from Gemini, INT (Montes et al. 2021), and DECaLS. In the left and middle panels, the horizontal dashed lines represent the expected color values based on the Vazdekis et al. (2016) models for different metallicities at a fixed age of 8.5 Gyr (left panel) and for different ages at a fixed [Fe/H] of −1.18 (middle panel). The right panel shows the stellar mass density profile of NGC 1052-DF2.
