PS1 z>5.6 QSO Survey. II. 55 quasars follow-up
Listed in IVOA Registry (Virtual Observatory)
The identification of bright quasars at z>~6 enables detailed studies of supermassive black holes, massive galaxies, structure formation, and the state of the intergalactic medium within the first billion years after the Big Bang.
Description
We present the spectroscopic confirmation of 55 quasars at redshifts 5.6<z<6.5 and UV magnitudes -24.5<M_1450_{<}-28.5 identified in the optical Pan-STARRS1 and near-IR VIKING surveys (48 and 7, respectively).
Five of these quasars have independently been discovered in other studies. The quasar sample shows an extensive range of physical properties, including 17 objects with weak emission lines, 10 broad absorption line quasars, and 5 objects with strong radio emission (radio-loud quasars). There are also a few notable sources in the sample, including a blazar candidate at z=6.23, a likely gravitationally lensed quasar at z=6.41, and a z=5.84 quasar in the outskirts of the nearby (D~3Mpc) spiral galaxy M81.

The blazar candidate remains undetected in NOEMA observations of the [CII] and underlying emission, implying a star formation rate <30-70M_{sun}_/yr. A significant fraction of the quasars presented here lies at the foundation of the first measurement of the z~6 quasar luminosity function from Pan-STARRS1 (introduced in a companion paper). These quasars will enable further studies of the high-redshift quasar population with current and future facilities.
