TLDR
McCarthy et al. as mentioned in this paper showed that 3C 265 does not show the alignment effect that is common in distant galaxies: the EELR is not extended along the radio axis.Abstract:
3C 265 is a high-redshift (z=0811) radio galaxy showing extended emission line regions (EELR) to 50 kpc from the nucleus (McCarthy et al 1995) However, it does not show the alignment effect (McCarthy 1993) that is common in distant galaxies: the EELR is not extended along the radio axisread more

Scattered Nuclear Continuum and Broad H-alpha in Cygnus A
TL;DR: In this article, scattered broad Balmer emission lines in the spectrum of Cygnus A, using the Keck II telescope, were discovered, consistent with scattering of light from a hidden quasar of modest luminosity.

Polarimetry and Unification of Low-Redshift Radio Galaxies
Marshall H. Cohen,Patrick Ogle,Patrick Ogle,Hien D. Tran,Hien D. Tran,Robert W. Goodrich,Joseph S. Miller +6 more
TL;DR: In this article, the authors made high-quality measurements of the polarization spectra of 13 FR II radio galaxies and taken polarization images for 11 of these with the Keck telescopes.

Scattered Radiation from Obscured Quasars in Distant Radio Galaxies
TL;DR: In this article, a broad Mg II?2800 emission line is detected in the total and polarized flux spectra of 3C 265 and 3C 277.2, and the radio jets lie inside the extended emission regions and are roughly perpendicular to the polarization position angle.

The UV Radiation from z ~ 2.5 Radio Galaxies: Keck Spectropolarimetry of 4C 23.56 and 4C 00.54
TL;DR: In this article, the authors present the results of deep spectropolarimetry of two powerful radio galaxies at z~2.5 (4C 00.54 and 4C 23.56) that was obtained with the W. M. Keck II 10 m telescope and which was aimed at studying the relative contribution of the stellar and non-stellar components to the ultraviolet continuum.

The Alignment Effect in Radio—Loud AGN: Ten Years After
TL;DR: In this paper, the alignment effect is likely due to a combination of anisotropic scattering and nebular continuum, with possible contributions from star formation in some objects, and an important outcome of the study of the alignment is the realization of the multicomponent nature of the AGN environment.

The nature of the optical filaments in Centaurus A. Evidence for a beamed ionizing continuum
R. Morganti,Andrew Robinson,R. A. E. Fosbury,S. di Serego Alighieri,Clive Tadhunter,David Malin +5 more
TL;DR: In this paper, the optical filaments in Centaurus A were analyzed using both narrow-band imaging and long-slit spectroscopy, showing that the line-emitting filaments are complex and highly structured at the limit of ground-based resolution.

Very large array imaging of five Fanaroff-Riley II 3CR radio galaxies
TL;DR: In this article, the radio cores of five luminous classical double radio galaxies (RGs) at 5 GHz were detected and compared at three different wavelengths: 3.6, 6, and 20 cm.
