On the large-scale structure of galactic disks

Abstract

The disk positions for galaxies of various morphological and nuclear-activity types (normal galaxies, QSO, Sy, E/S0, low-surface brightness galaxies, etc.) on the "central surface brightness - exponential scalelength" plane are considered. The stellar disks are shown to form a single sequence on this plane over a wide range of surface brightnesses (μ_0(I)=12-25) and sizes (h=10 pc - 100 kpc). The existence of this observed sequence can probably be explaned by a combination of three factors: a disk-stability requirement, a limited total disk luminosity, and observational selection. The model by Mo et al. (1998) for disk formation in the CDM hierarchical-clustering scenario is shown to satisfactorily reproduce the salient features of the galaxy disk distribution on the "μ_0 - h" plane.
