TL;DR
This paper discusses the UKIDSS survey's capabilities and initial findings in searching for high-redshift quasars, reporting two new discoveries and confirming previous ones, thus advancing understanding of early universe objects.
Contribution
It introduces the UKIDSS LAS survey's potential for detecting distant quasars and reports the first discoveries from its third data release.
Findings
Discovered two new quasars at z > 6.
Confirmed two previously known high-redshift quasars.
Demonstrated survey's effectiveness in early universe studies.
Abstract
The UKIRT Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS) has the necessary combination of filters (Y, J, H and K), depth (Y <~ 20.2) and area coverage (~4000 deg^2) to detect several redshift z >~ 6.4 quasars. The Third Data Release (DR3) included ~1000 deg^2 of LAS observations which have so far yielded two previously known z ~= 6 quasars and two new discoveries: ULAS J0203+0012, at z = 5.72; and ULAS J1319+0950, at z = 6.13.
