Search for high redshift QSOs (5.8<z<6.7)

Using a i-drop out selection technique with the SkyMapper i and z filters, we can expect to find up to 30 high redshift quasars (5.8 < z < 6.7) brighter than Z < 20 mag in the entire SkyMapper southern sky survey. We would be able to increase by more than a factor two the numbers of bright high redshift QSOs known in this range of redshift and therefore obtain better constraint on the period of reionisation of our Universe.
