NuSTAR OBSERVATIONS OF HEAVILY

Abstract

We present NuSTAR hard X-ray observations of three Type 2 quasars at z ≈ 0.4–0.5, optically selected from the Sloan Digital Sky Survey. Although the quasars show evidence for being heavily obscured, Compton-thick systems on the basis of the 2–10 keV to [O iii] luminosity ratio and multiwavelength diagnostics, their X-ray absorbing column densities (NH) are… (More)
