NEW: We have finally submitted the SDSS Quasar Luminosity Function paper. You can obtain a preprint here.

For the most recent version (currently DR3) of the photometric quasar catalog that was derived using a Kernel Density Algorithm in order to do a Non-parametric Bayesian Classification, see http://sdss.ncsa.uiuc.edu/qso/nbckde/. The 2004 paper explaining the algorithm and catalog construction can also be found there.

My CV (PS)(PDF) and Bibliography (PS)(PDF) are current as of December 2005, everything else may or may not be up to date.
