In the Lambda-CDM model, the accelerating expansion of the universe begins at a scale factor equal to this function of omega-sub-matter over two omega-sub-lambda.
In the Lambda-CDM model, the accelerating expansion of the universe begins at a scale factor equal to this function of omega-sub-matter over two omega-sub-lambda. The radius of a Strömgren sphere is proportional to this function of ionizing photon emission rate over recombination rate. The ratio of the cosmic neutrino background temperature to the CMB temperature is this function of four-elevenths. A white dwarf's ordinary and relativistic polytropic equations of state di fer by a factor of this function of density; therefore, in the limit of low mass, the radius of a white dwarf is inversely proportional to this function of its mass. Applying this operation to both sides of Kepler's third law gives an orbit's semi-major axis in terms of this function of the square of its period. For 10 points, name this operation that, a ter dividing by four-thirds pi, is used to  nd the radius of a sphere of known volume.
