A DIRECT MEASUREMENT OF THE LINEAR BIAS OF MID-INFRARED-SELECTED QUASARS AT <i>z</i> โ‰ˆ 1 USING COSMIC MICROWAVE BACKGROUND LENSING

We measure the cross-power spectrum of the projected mass density as traced by the convergence of the cosmic microwave background lensing field from the South Pole Telescope (SPT) and a sample of Type 1 and 2 (unobscured and obscured) quasars at ใ€ˆzใ€‰ โˆผ 1 selected with the Wide-field Infrared Survey โ€ฆ
