Scientific paper

We present the results obtained from a 40 ks RGS analysis of the Broad Line Radio Galaxy (BLRG) 3C 382 (z=0.0579). For the first time, narrow absorption lines are unambiguously detected in a BLRG, providing striking evidence for a warm absorber (WA) gas. We constrained the physical parameters of this gas fitting the data with the photoionisation code XSTAR. It appears to be highly ionised with a column density of the order of 1022 cm-2, an ionisation parameter logξ>2 and outflow velocities of the order of 103 km s-1. These findings show that WA can be present also in RL AGNs exhibiting strong jets, and moreover suggest the possible coexistence of relativistic collimated plasma and slower outflows of photoionised gas in the same object.
