Abstract

An infrared-selected, narrow-line quasi-stellar object has been found to exhibit an extraordinarily broad Hα emission line in polarized light. Both the extreme width (35,000 km s-1 full-width at zero intensity) and 3,000 km s-1 redshift of the line centroid with respect to the systemic velocity suggest emission in a deep gravitational potential. An extremely red polarized continuum and partial scattering of the narrow lines at a position angle common to the broad-line emission imply extensive obscuration, with few unimpeded lines of sight to the nucleus.
