The structure of galactic disks: Studying late-type spiral galaxies using SDSS
Open accessAbstract
Using imaging data from the SDSS survey, we present the and radial stellar light distribution of a complete sample of ~90 face-on to intermediate inclined, nearby, late-type (Sb–Sdm) spiral galaxies. The surface brightness profiles are reliable ( uncertainty less than 0.2 mag) down to mag . Only ~10% of all galaxies have a normal/standard purely exponential disk down to our noise limit. The surface brightness distribution of the rest of the galaxies is better described as a broken exponential. About 60% of the galaxies have a break in the exponential profile between ∼1.5–4.5 times the scalelength followed by a downbending, steeper outer region. Another ~30% shows also a clear break between ∼4.0–6.0 times the scalelength but followed by an upbending, shallower outer region. A few galaxies have even a more complex surface brightness distribution. The shape of the profiles correlates with Hubble type. Downbending breaks are more frequent in later Hubble types while the fraction of upbending breaks rises towards earlier types. No clear relation is found between the environment, as characterised by the number of neighbours, and the shape of the profiles of the galaxies.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
