PKS 1932-464: a jet-cloud interaction in a radio galaxy?
M. Villar-Martin, C. N. Tadhunter, R. Morganti +3
We present optical and radio images, and long-slit spectra of the radio galaxy PKS 1932-464 (z=0.230). Our main goal is to determine whether the observed properties of the extended…

The ionization mechanism of the extended gas in high redshift radio galaxies:shocks or AGN photoionization?
M. Villar-Martin, C. N. Tadhunter, N. E. Clark
We have compared the UV line ratios of a sample of very high redshift radio galaxies with shock and AGN photoionization models, with the goal of determining the balance between jet…
