J/A+A/389/795 Vertical structure of edge-on galaxies (Bizyaev+, 2002) ================================================================================ Photometric parameters of edge-on galaxies from 2MASS observations. Bizyaev D., Mitronova S. =2002A&A...389..795B ================================================================================ ADC_Keywords: Galaxies, photometry ; Photometry, surface ; Photometry, infrared Keywords: galaxies: structure - galaxies: photometry Abstract: To analyze the vertical structure of edge-on galaxies, we have used images of a large uniform sample of flat galaxies that have been taken during the 2MASS all-sky survey. The photometric parameters, such as the radial scale length, the vertical scale height, and the deprojected central surface brightness of galactic disks have been obtained. We find a strong correlation between the central surface brightness and the ratio of the vertical scale height to the vertical scale length: the thinner the galaxy, the lower the central surface brightness of its disk. The vertical scale height does not increase systematically with the distance from the galaxy center in the frames of this sample.
