Surface Brightness Plateau in S4G Galaxies
Using 3.6-μm data from 2112 galaxies, we show that, contrary to widely held expectations of a continuous steep decline, radial surface brightness profiles of galaxies tend to flatten and form extended plateaus beyond 27–28 mag<sub>AB</sub>/arcsec². This phenomenon could be explained by t...
