Description

Optical broadband polarimetry is presented for near-infrared color-selected active galactic nuclei (AGNs) classified as quasi-stellar objects (QSOs) based on their Ks-band luminosity. More than 10% of a sample of 70 QSOs discovered in the Two Micron All Sky Survey (2MASS, Cat. <B/2mass>) with J-Ks>2 and M_Ks_<-23 show high broadband linear polarization (P>3%), and values range to a maximum of P~11%. High polarization tends to be associated with the most luminous objects at Ks and with QSOs having the highest near-IR to optical flux ratios. The 2MASS QSO sample includes objects possessing a wide range of optical spectral types. High polarization is seen in two of 22 broad emission-line (type 1) objects, but ~1/4 of the QSOs of intermediate spectral type (type 1.5-1.9) are highly polarized. None of the nine QSOs classified as type 2 exhibit P>3%.
