Abstract

An infrared-selected, narrow-line QSO 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. Subject headings: quasars: emission lines — quasars: individual (2MASSI J130005.3+163214) — galaxies: active — polarization 1. introduction If the Unified Scheme for AGN (e.g., Antonucci 1993) is to be equally successful for objects of high as well as low luminosity, there should exist a large number of QSOs whose optical/UV spectra are dominated by narrow emission lines (Type 2 QSOs or QSO-2s).
