These will be used in subsequent papers for detailed studies of profile shapes and parameter systematics. The present qualitative discussion yields the following results: 1. Red compacts are qualitatively E and SO galaxies Cited by:   Freeman's central disk brightness B(O)c is usually normal, i.e., B mag (hereafter B, but is faint in I Zw 21( B and VII Zw ( B. This confirms a general suspicion that there exist galaxies with faint disks. The scale lengths are 7 kpc (H0 = 50 km s - Mpc 1), at the long end of the normal by: A study was made of three problems on luminosity distributions in galaxies: the nature of red compact galaxies, the systematic properties of spheroids, and the effect of decomposing observed profiles into spheroid and disk components. Photographic brightness profiles were measured for sixteen compact and four normal galaxies. A systematic study of galaxy spheroids was also made by fitting the.

SURFACE BRIGHTNESS PROFILES OF COMPOSITE IMAGES OF COMPACT GALAXIES surface-brightness distributions of the brightest Lyman Break Galaxies (LBGs) at brightness profiles of z 4–6 galaxies, and in Section 6 we conclude with a summary of our. Surface brightness distributions in the faint outer regions of 19 elliptical and S0 galaxies are presented, and it is argued that these distributions are more reliable than those previously published. A low-surface-brightness galaxy, or LSB galaxy, is a diffuse galaxy with a surface brightness that, when viewed from Earth, is at least one magnitude lower than the ambient night sky.. Most LSBs are dwarf galaxies, and most of their baryonic matter is in the form of neutral gaseous hydrogen, rather than stars. They appear to have over 95% of their mass as non-baryonic dark matter.   Kormendy, J.: Brightness distributions in compact and normal galaxies.
