Title: The Southern Extremely Luminous Quasar Survey (ELQS) at z~3-5

Abstract: Statistical samples of luminous quasars are important probes for the evolution of super-massive black holes. They further facilitate research on the intergalactic medium, circum-galactic gas, fundamental constants and large-scale structure formation in the Universe through absorption line studies and incited extended Ly{$alpha$} emission. While their potential to serve as useful probes for these areas of research is directly proportional to their luminosity, extremely luminous quasars are very rare. We have developed a candidate selection based on complementary near-infrared and optical photometry with focus on high completeness. In the past year we have successfully discovered $>30$ new QSOs with $i <17.5$ at $z=2.5-4.5$ in the already well surveyed SDSS footprint. The recently published PanSTARRS photometry allows us to extend this survey to an additional 00,rm^2$ in the southern hemisphere. We propose to to carry out a survey for extremely luminous ($i<18.5$) quasars at $z=3-5$ limited to the southern galactic cap ($gtrsim3700,rm^2$), a region that has yet to be mapped by quasar surveys. This survey will triple the number of known luminous quasars in that area. It will provide invaluable targets for cosmology and extragalactic astronomy, making use of the powerful telescopes of the southern hemisphere.
