J/ApJ/674/668       SDSS J102839.11+450009.4 Fe II emission lines  (Wang+, 2008)

ADC_Keywords: QSOs ; Spectroscopy Keywords: quasars: absorption lines - quasars: emission lines - quasars: individual (SDSS J102839.11+450009.4) Abstract: We report identification of SDSS J102839.11+450009.4 as a peculiarly interesting quasar. It shows very prominent narrow emission lines (NELs) in FeII that are remarkably different from the broad FeII multiplets commonly observed in quasars and Seyfert 1 galaxies. The FeII NEL spectrum is dominated in the UV by transitions to the low-lying ground levels with even parity, and by forbidden transitions in the optical, suggesting its formation in a warm collisionally ionized low density medium. Description: SDSS J1028+4500 was observed spectroscopically as a quasar target during the Sloan Digital Sky Survey with a total exposure time of 4219s.
