One deviation from this law is a result of "pancaking" via the Kaiser Effect, while application of t
One deviation from this law is a result of "pancaking" via the Kaiser Effect, while application of the virial theorem explains another deviation known as the Fingers of God. In some cases, the quadratic Lundmark's Law fits better than this relation, and it can be derived from the Friedman-Robertson- Walker equations. The change in one quantity in this law is dependent on the sign of the deceleration parameter q, and measuring anisotropies in the CMB all give a value around 70 for this law's namesake parameter. FTP, name this law which states that the redshift of an astronomical object is proportional to its distance from the observer, named for an American cosmologist and namesake of a giant space telescope.
