A Left and Right Truncated Schechter Luminosity Function for Quasars

A Left and Right Truncated Schechter Luminosity Function for Quasars

The luminosity function for quasars (QSOs) is usually fitted by a Schechter function. The dependence of the number of quasars on the redshift, both in the low and high luminosity regions, requires the inclusion of a lower and upper boundary in the Schechter function. The normalization of the truncat...
