Extended emission-line regions ( EELRs ) , found around radio loud sources , are likely outflows driven by one form of powerful AGN feedback mechanism .
We seek to constrain the three-dimensional gas properties and the outflow energetics of the EELRs in this study .
We used an integral field unit to observe EELRs around two samples of of radio loud AGNs with similar radio properties but different orientations : a sample of quasars and a sample of radio galaxies .
A morphological comparison suggests a scenario where the three-dimensional EELR gas distribution follows rough biconical shapes with wide opening angles .
The average extent of the EELRs is \sim 18.5 kpc .
The estimated average mass of the EELRs , with reasonable assumptions for gas densities , is \sim 3 \times 10 ^ { 8 } M _ { \odot } , and the average mass outflow rate is \sim 30 M _ { \odot } /yr .
The EELRs around quasars and radio galaxies share similar kinematic properties .
Both samples have velocity structures that display a range of complexities and they do not appear to correlate with the jet orientations , and both span a similar range of velocity dispersions .
Around 30 % of the detected EELRs show large scale rotational motions , which may have originated from recent mergers involving gas-rich disk galaxies .
