A nine-year survey of this phenomenon conducted by the Center for Astrophysics led to the discovery of the Great Wall supercluster.
A nine-year survey of this phenomenon conducted by the Center for Astrophysics led to the discovery of the Great Wall supercluster. One quantity with this name is equal to GM over c squared times R in the gravitational case, and is roughly equal to relativistic beta for low velocities. That quantity, symbolized z, has been measured at values as high as (*) 9.4 for gamma ray bursts and 7.1 for quasars. The expansion of the universe means that this effect is universally observed in cosmological radiation, because it arises from the Doppler effect for an emitter moving away from an observer. For 10 points, name this increase in radiation wavelength, named for a long-wavelength color.
