Title: Spectroscopic identification of new low-luminosity quasars at z > 6

Abstract: High-redshift quasars are an important probe of the distant universe. They enable observational studies of the early growth of supermassive black holes, the cosmic reionization, and the evolution of the host galaxies, among others. We are now starting a new ground-breaking survey for high-z (z > 6) quasars over 1,400 deg2 with a wide-field camera, Hyper Suprime-Cam (HSC), mounted on the Subaru 8.2-m telescope. We will probe the most distant quasars down to ~2 mag lower luminosity (M1450 < -22 mag) than any previous survey, and will increase the number of known z > 6 quasars by almost an order of magnitude. Here we propose Gemini/GMOS spectroscopy of the latest ten candidates. They are securely detected in more than a single band and have very high Bayesian probabilities of being z > 6 quasars. Our immediate objectives are (i) to achieve the first discovery of HSC high-z quasars; (ii) to get a new constraint on their luminosity function; and (iii) to evaluate our grand survey strategy.
