Giant Radio Quasars: Sample and Basic Properties

We present the largest sample of giant radio quasars (GRQs), which are defined as having a projected linear size greater than 0.7 Mpc. The consists 272 GRQs, 174 new objects discovered through cross-matching NRAO VLA Sky Survey (NVSS) and Sloan Digital 14$^{\rm th}$ Data Release Quasar Catalogue (DR14Q) confirmed using Faint Images Radio at Twenty-Centimeters (FIRST) maps. In our analysis we compare GRQs with 367 smaller, lobe-dominated found search method, well from SDSS DR14 Catalogue, investigating parameters characterizing their emission (i.e. total core luminosity, prominence), optical properties (black hole masses, accretion rates, distribution in Eigenvector 1 plane) infrared colours. For smaller find strong correlation between [OIII] luminosity 1.4 GHz, indicating connection conditions narrow-line region. spot no significant differences quasars, however show that most extended belong to quasar population evolved AGNs large black masses low rates. also have bluer W2-W3 colours compared FIRST detections, structure dusty torus.
