XMM - Newton Observation of Fe K α emission from a BAL QSO : Mrk 231
We present results from a 20 ksec XMM-Newton observation of Mrk 231. EPIC spectral data reveal strong line emission due to Fe Kα, which has rarely been detected in this class, as BAL QSOs are very faint in the X-ray band. The line energy is consistent with an origin in neutral Fe. The width of the line is equivalent to a velocity dispersion ∼ 18, 000 km s and thus the line may be attributed to ...

متن کامل0 Stellar Populations in the Host Galaxies of Mrk 1014 , IRAS 07598 + 6508 , and Mrk 231
We present deep spectroscopic and imaging data of the host galaxies of Mrk 1014, IRAS 07598+6508, and Mrk 231. These objects form part of both the QSO and the ultraluminous infrared galaxy (ULIG) families, and may represent a transition stage in an evolutionary scenario. Our imaging shows that all three objects have highly perturbed hosts with tidal tails and destroyed disks, and appear to be i...
متن کاملMolecular QSO Absorption Line Systems
We review observations of molecular absorption line systems at high redshift toward red quasars and gravitational lenses. The steeply falling power law column density distribution function of QSO absorption line systems implies that for every 1000 Ly α forest lines from absorbers with hydrogen column density, NH < 10 15 cm there will be only one system with NH ≥ 10 cm (Hu et al. 1995). Although...
متن کاملVLBI Imaging of Luminous Infrared Galaxies : AGN Cores in Mrk 231 , UGC 5101 & NGC 7469
We report 18cm VLBI continuum imaging observations at ∼5 milliarcsecond resolution for UGC 5101, NGC 7469, and Mrk 231, all part of a sample of Luminous Infrared Galaxies which have been shown to have strong VLBI radio cores in a previous 18cm VLBI survey. Mrk 231, generally considered to be a dust-enshrouded QSO, shares many characteristics with quasars, including a broad, Sy1 optical emission...
