Surface Brightness Plateau in S4G Galaxies

Autor: Alan Sipols, Alex Pavlovich

Publikováno v: Galaxies, Vol 8, Iss 2, p 48 (2020)

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 magAB/arcsec2. This phen

Most radiative transfer models assume that dust in spiral galaxies is distributed exponentially. In this paper our goal is to verify this assumption by analysing the two-dimensional large-scale distribution of dust in galaxies from the DustPedia samp
