An Extraordinary Scattered Broad Emission Line in a Type 2 Qso
نویسندگان
چکیده
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 full-width at zero intensity) and 3,000 km s 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

A microlensing measurement of the size of the broad emission line region in the lensed QSO 2237 + 0305
We present spatially resolved spectroscopic images of the gravitationally lensed QSO 2237+0305 taken with the GMOS Integral Field Unit (IFU) on the Gemini North telescope. These observations have the best spatial resolution of any IFU observations of this object to date and include the redshifted C iii] and Mg ii QSO broad lines. Unlike Mediavilla et al. (1998), we find no evidence for an arc o...
متن کاملX-raying the Ultraluminous Infrared Starburst Galaxy and Broad Absorption Line Qso, Markarian 231, with Chandra
With 40 ks of Chandra ACIS-S3 exposure, new information on both the starburst and QSO components of the X-ray emission of Markarian 231, an ultraluminous infrared galaxy and Broad Absorption Line QSO, has been obtained. The bulk of the X-ray luminosity is emitted from an unresolved nuclear point source, and the spectrum is remarkably hard with the majority of the flux emitted above 2 keV. Most ...
متن کاملX-Rays from the Highly Polarized Broad Absorption Line QSO CSO 755.
We present results from a BeppoSAX observation of the broad absorption line (BAL) QSO CSO 755, which was observed as part of our program to investigate the X-ray properties of highly polarized BAL QSOs. CSO 755 is clearly detected by the BeppoSAX Medium-Energy Concentrator Spectrometers, making it the highest redshift (z=2.88) and most optically luminous (MV=-27.4) BAL QSO seen in X-rays. It is...
متن کاملThe Formation of Broad Emission Line Regions in Supernova-QSO Wind Interactions
We show that a cooled region of shocked supernova ejecta forms in a type II supernova-QSO wind interaction, and has a density, an ionization parameter, and a column density compatible with those inferred for the high ionization component of the broad emission line regions in QSOs. The calculations are based on the assumption that the ejecta flow is described initially by a similarity solution i...
متن کاملA candidate of a type - 2 QSO at z = 0 . 9 : Large X - ray absorption with a strong broad - H α emission line 1
Deep hard X-ray and near infrared observations of a type-2 radio-quiet QSO candidate at z = 0.9, AX J08494+4454, are reported. The 0.5–10 keV Chandra X-ray Observatory spectrum of AX J08494+4454 is hard, and is explained well with a power-law continuum absorbed by a hydrogen column density of (2.3± 1.1)× 10 cm. The 2–10 keV luminosity of the object is estimated to be 7.2 −2.0× 10 44 erg s, afte...
