The '''Hubble–Reynolds law''' models the [[surface brightness]] of [[elliptical galaxy|elliptical galaxies]] as
 
:<math>I(R) = \frac{I_0}{(1+R/R_H)^2}</math>
 
Where <math>I(R)</math> is the [[surface brightness]] at radius <math>R</math>, <math>I_0</math> is the central brightness, and <math>R_H</math> is the radius at which the surface brightness is diminished by a factor of 1/4. It is asymptotically similar to the [[de Vaucouleurs law]] which is a special case of the [[Sérsic law]] for elliptical galaxies.<ref>Binney & Tremaine. ''Galactic Dynamics'' 2008.</ref>
 
The law is named for the astronomers [[Edwin Hubble]] and [[John Reynolds (astronomer)|John Henry Reynolds]].

Hi there. My title is Garland although it is not the title on my beginning certification. Playing crochet is a factor that I'm totally addicted to. I am a production and distribution officer. Arizona is her birth place and she will by no means move.
