Introduction: Binary Quasar Candidates in SDSS
Double-peaked [O III] lines in SDSSe. g. Liu et al. (2010a), Smith et al. (2010)Follow-up observations:NIR and optical imaging, slit spectroscopy, IFU spectroscopy(Rosario et al. 2011; Liu et al. 2010b; Shen et al. 2011; Fu et al. 2012)
VIMOS – [O III] spectra integrated over FOVDiagnostics following Blecha et al. (2012) and Smith et al. (2011)Peak separation [km/s]: 270, 400, 400, 300Centroid offset from vsys [km/s]: 8, 1, 18, 46 (" no BH influence?)Ratios of peak fluxes: 0.7, 0.7, 0.7, 0.9 (" no BH influence?)

VIMOS – Summary of results
No obvious binary sources in continuum emission! study in more detail[O III] emission 2– 3 kpc, mostly aligned with continuum2 kinematic components overlap in spaceDouble-peaked [O III] 5007, H! in spatially resolvedspectraSigns of rotation (?)[O III] / Hb ratio generally high
Further exploration of VIMOS data
Explore the velocity spacemore kinematic models, more realisticinclude overlapping NLRs from 2 AGNuse all the possible mappings (I, v, FWHM, channel maps,p-v diagrams) to determine best-fitting modelFourier decomposition (kinemetry, Krajnovic et al. 2006)
Combine gas emission data with stellar continuumLook for disturbed morphologies indicating mergersAbsorption lines (e.g. Mg 5170) and the 4000Å jump! derive stellar kinematics, population ages
Search for other emission linese. g. [O III] 4363Å! derive temperature
