The authors have analyzed luminosity profiles of E galaxies in six clusters of galaxies. They have found a relationship between radius, luminosity and surface brightness for galaxies in each of the clusters. Moreover, it seems that there is a dependence of the zero point of the relation with ...
We have found a relationship between radius, luminosity, and surface brightness for galaxies in each of the clusters. A dependence of the zero point of the relation with the local projected density of galaxies is likewise found: r e 蟻 proj 0.14 L 0.445 I e 0.413 . This relationship ...

There's a blue-yellow and a red-green chroma component. Intensity / Luminosity / LumaIn general, intensity is a synonym for magnitude, degree or strength. It can therefore be used in conjunction with any color property. Nevertheless, it carries special meaning in certain contexts. For ...
Seasonal effects on auroral particle acceleration and precipitation The energy flux of precipitating electrons is inferred from auroral luminosity in the long-wavelength bands (1600–1800 Å) of N2 Lyman-Birge-Hopfield (... K.,Liou,P.,... - 《Journal of Geophysical Research》 被引量: 340发表...

The light output of the sun is often discussed in two different ways: either as the solar luminosity, which is the sun's omnidirectional radiant output, or as the solar constant, the output seen in the direction of the Earth. In this chapter, we explore the variable solar light output ...
