TL;DR
The LAMOST Quasar Survey aims to discover 0.4 million new quasars using improved selection criteria, enhancing the understanding of AGN physics and cosmology, and addressing the redshift desert challenge.
Contribution
This paper introduces new quasar selection criteria based on UKIDSS and SDSS colors, improving detection of quasars in the redshift desert.
Findings
Discovered new quasars during LAMOST commissioning phase.
Demonstrated advantages of near-IR and optical color criteria.
Projected to find 0.4 million quasars in 5 years.
Abstract
The main objective of the Chinese LAMOST spectroscopic quasar survey is to discover 0.4 million new quasars from 1 million quasar candidates brighter than the magnitude limit i=20.5 in the next 5 years. This will hopefully provide the largest quasar sample for the further studies of AGN physics and cosmology. The improved quasar selection criteria based on the UKIDSS near-IR and SDSS optical colors are presented, and their advantages in uncovering the missing quasars in the quasar 'redshift desert' are demonstrated. In addition, some recent discoveries of new quasars during the LAMOST commissioning phase are presented.
