X-shaped Radio Galaxies: Optical Properties, Large-scale Environment, and Relationship to Radio Structure [PDF]
Astrophysical Journal, 2019 In pursuit of clues to the origin of “winged” or X-shaped radio galaxies (XRGs) we investigate the parent galaxies of a large sample of 106 XRGs for optical–radio axes alignment, interstellar medium, black hole mass, and large-scale environment.

Dynamical analysis of the complex radio structure in 3C 293: clues on a rapid jet realignment in X-shaped radio galaxies [PDF]
, 2016 Context. Radio galaxies classified as X-shaped/winged, are characterised by two pairs of extended and misaligned lobes, which suggest a rapid realignment of the jet axis, for which a potential cause (including binary supermassive black holes, a black ...

CGCG 292-057 - a radio galaxy with merger-modulated radio activity [PDF]
, 2012 We announce the discovery of a unique combination of features in a radio source identified with the merger galaxy CGCG 292−057. The radio galaxy both exhibits a highly complex, X-like structure and shows signs of recurrent activity in the form of double ...

Starbursts and black hole masses in X-shaped radio galaxies: Signatures of a merger event? [PDF]
, 2012 We present new spectroscopic identifications of 12 X-shaped radio galaxies and use the spectral data to derive starburst histories and masses of the nuclear supermassive black holes in these galaxies.

Host Galaxies of X-Shaped Radio Sources
, 2006 The majority of radiation from galaxies containing active galactic nuclei (AGNs) is emitted not by the stars composing the galaxy, but from an active source at the galactic center, most likely a supermassive black hole.
