Trends for Outer Disk Profiles
Peter Erwin, Michael Pohlen, Leonel Gutierrez, and John E. Beckman
TL;DR
This paper reviews the different types of surface-brightness profiles in galaxy disks, exploring how their frequencies vary with galaxy type, environment, and bars, providing insights for disk formation theories.
Contribution
It categorizes galaxy disk profiles into three main types and analyzes their dependence on galaxy properties, offering new observational constraints for formation models.
Findings
Type I, II, and III profiles have distinct frequency distributions.
Profile types correlate with galaxy Hubble type and environment.
Bars influence the prevalence of certain profile types.
Abstract
The surface-brightness profiles of galaxy disks fall into three main classes, based on whether they are simple exponentials (Type I), bend down at large radii (Type II, "truncations") or bend up at large radii (Type III, "antitruncations"). Here, we discuss how the frequency of these different profiles depends on Hubble type, environment, and the presence or absence of bars; these trends may herald important new tests for disk formation models.
