SDSS J102839.11+450009.4 Fe II emission lines
Listed in IVOA Registry (Virtual Observatory)
We report identification of SDSS J102839.11+450009.4 as a peculiarly interesting quasar.
Description
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.
