[OIII] Emission Line Properties in a New Sample of Heavily Reddened Quasars at $z>2$

We present VLT-SINFONI near infra-red spectra of 26 new heavily reddened quasarcandidates selected from the UKIDSS-LAS, VISTA VHS and VIKING imaging surveys. This new sample extends our reddened quasarsearch to both brighter and fainter luminosities. 25 of the 26 candidates are confirmed to be broad line quasarswith redshifts $0.7 2$. We present the first comparison of the [OIII] line properties in high luminosityobscured quasarsto a large sample of 111 unobscured quasarsin the same luminosityand redshift range. Broad wings extending to velocities of 2500 km/s are seen in the [OIII] emission line profiles of our reddened quasars, suggesting that strong outflows are affecting the ionised gas kinematics. However, we find no significant difference between the kinematics of the [OIII] emission in reddened and unobscured quasarswhen the two samples are matched in luminosityand redshift. Our results are consistent with a model where quasar-driven outflows persist for some time after the obscuring dust has been cleared from along the line of sight. Assuming the amount of ionised gas in obscured and unobscured quasarsis similar, we use the equivalent widthdistribution of the [OIII] emission to constrain the location of the obscuring dust in our reddened quasars. We find that the dust is most likely to be located on galactic scales, outside the [OIII] emitting region.
