The GALEX/S4G Surface Brightness and Color Profiles Catalog. I. Surface Photometry and Color Gradients of Galaxies
2018
Astrophysical Journal Supplement Series
We present new, spatially resolved, surface photometry in FUV and NUV from images obtained by the Galaxy Evolution Explorer (GALEX), and IRAC1 (3.6 μm) photometry from the Spitzer Survey of Stellar Structure in Galaxies (S^4G) (Sheth et al. 2010). We analyze the radial surface brightness profiles μ_FUV, μ_NUV, and μ_[3.6], as well as the radial profiles of (FUV - NUV), (NUV - [3.6]), and (FUV - [3.6]) colors in 1931 nearby galaxies (z < 0.01). The analysis of the 3.6 μm surface brightness
