We present simulations of quasar colors, magnitudes, and numbers at redshifts 5 6 epoch, taking advantage of the new UKIRT Infrared Deep Sky Survey near-infrared filter set, and we examine the redshift intervals of maximum productivity, discussing color selection and survey depth issues. On the basis of the SDSS sample, we find that the surface density of z > 4.7 quasars increases by a factor of 3 times by extending 0.7 i magnitudes deeper than the SDSS spectroscopic survey limit of i = 20.2… Expand
The Discovery of Three New z > 5 Quasars in the AGN and Galaxy Evolution Survey
We present the discovery of three z > 5 quasars in the AGN and Galaxy Evolution Survey spectroscopic observations of the NOAO Deep Wide-Field Survey (NDWFS) Bootes Field. These quasars were selectedExpand
A survey of luminous high-redshift quasars with SDSS and WISE. I. target selection and optical spectroscopy
High-redshift quasars are important tracers of structure and evolution in the early universe. However, they are very rare and difficult to find when using color selection because of contaminationExpand

The possible detection of high‐redshift Type II QSOs in deep fields
The colours of high-redshift Type II quasi-stellar objects (QSOs) are synthesized from observations of moderate-redshift systems. It is shown that Type II QSOs are comparable to starbursts atExpand
Discovery of the Most Ultra-Luminous QSO Using GAIA, SkyMapper, and WISE
Abstract We report the discovery of the ultra-luminous quasi-stellar object SMSS J215728.21−360215.1 with magnitude z = 16.9 and W4 = 7.42 at redshift 4.75. Given absolute magnitudes of M145, AB =Expand
A search for z= 7.3 Lyα emitters behind gravitationally lensing clusters
We searched for z= 7.3 Lyα emitters (LAEs) behind two gravitationally lensing clusters, Abell 2390 and CL 0024, using the Subaru Telescope Suprime-Cam and a narrow-band filter NB1006 (λc˜ 1005 nm andExpand
Star–galaxy separation strategies for WISE-2MASS all-sky infrared galaxy catalogues
We combine photometric information of the WISE and 2MASS all-sky infrared databases, and demonstrate how to produce clean and complete galaxy catalogs for future analyses. Adding 2MASS colors to WISEExpand
