We present initial results from the first systematic survey of luminous z∼ 5.5 quasars. Quasars at z ∼ 5.5, the post-reionization epoch, are crucial tools to explore the evolution of intergalactic medium, quasar evolution and the early super-massive black hole growth. However, it has been very challenging to select quasars at redshifts 5.3 < z < 5.7 using conventional color selections, due to their similar optical colors to late-type stars, especially M dwarfs, resulting in a glaring redshiftdoi:10.3847/1538-3881/aa6577 fatcat:uurbpayaavcllbhmj3264wnhxm
