A Wide and Deep Exploration of Radio-detected Active Galactic Nuclei with Subaru HSC (WERGS). XIII. High-z Radio Quasar Selection from HSC--VLASS over $\sim 1200$ deg $^{2}$

Youwen Kong, Kohei Ichikawa, Hisakazu Uchiyama +12

We report the results of $g -$ , $r -$ , $i -$ , and $z -$ dropout selections based on optical identifications of Very Large Array Sky Survey (VLASS) radio sources using the Hyper Suprime-…

A Wide and Deep Exploration of Radio-detected Active Galactic Nuclei with Subaru HSC (WERGS). XII. Final Optical Identification of VLASS Radio Sources from the Subaru/HSC-SSP Wide Survey Over 1200 deg $^{2}$

Hisakazu Uchiyama, Kohei Ichikawa, Youwen Kong +11

We present a wide-area and deep optical identification catalog for radio sources based on the VLASS Epoch 2 catalog at 3 GHz. Optical counterparts are identified using the final-ye…
