Galaxy surface brightness
http://astro.vaporia.com/start/surfacebrightnessprofile.html WebCosmological surface brightness (SB) dimming of the form (1 + z)−4 affects all sources. The strong dependence of SB dimming on redshift z suggests the presence of a selection bias when searching for high-z galaxies, i.e., we tend to detect only those galaxies with a high SB. However, unresolved knots of emission are not affected by SB

From Wikipedia's Milky Way; Appearance: The Milky Way is visible from Earth as a hazy band of white light, some 30° wide, arching across the night sky. [38] WebAug 10, 2013 · There are many sites that list surface brightness of Deep-Sky Objects. Most refer to magnitudes per square arc-minute (the familiar 13.5, 14.3, etc), and others use magnitudes per square arc-second (for example, you see night sky brightness expressed as 21.3, 21.7, etc.). Most professional astronomers use the mag./sq.arc-sec.
WebJan 1, 2003 · 1 Introduction. Surface brightness (SB) is one of the fundamental parameters describing a galaxy. It plays an important role in many diverse aspects of extragalactic astronomy and cosmology, from identifying the whole family of galaxy populations to modelling their different distributions and motions in the Universe.

In astronomy, surface brightness (SB) quantifies the apparent brightness or flux density per unit angular area of a spatially extended object such as a galaxy or nebula, or of the night sky background. An object's surface brightness depends on its surface luminosity density, i.e., its luminosity emitted per unit … See more The total magnitude is a measure of the brightness of an extended object such as a nebula, cluster, galaxy or comet. It can be obtained by summing up the luminosity over the area of the object. Alternatively, a photometer can … See more A truly dark sky has a surface brightness of 2×10 cd m or 21.8 mag arcsec .
