Alternative Cosmology Group Newsletter - July 2006
Posted July 20, 2006
Correction to June Newsletter:
Due to error on the part of the editor, the third item was
incorrectly described as confirming a constant surface brightens
of galaxies. In fact, the paper used old data from Lubin and
Sandage which implied a (z+1)^-3 variation in surface
brightness. The error is now corrected in the June newsletter.
Two papers on the difficulty of reconciling galaxy number
density and evolution models.
