Description
Studies of the evolution of active galactic nuclei (AGNs) have mostly used a single continuum slope to compute k-corrections. In this paper it is shown that allowing for the observed diversity of AGN continuum shapes greatly affects measurements of both the continuum slopes and number evolution. Less evolution is required between redshift two and the present, and a spurious correlation between continuum slope and redshift introduced in magnitude-limited samples. Two reported correlations...[Show more]
