A DEEP CHANDRA OBSERVATION OF THE X-SHAPED RADIO GALAXY 4C +00.58: A CANDIDATE FOR MERGER-INDUCED REORIENTATION? [PDF]
The Astrophysical Journal, 2010 Although rapid reorientation of a black hole spin axis (lasting less than a few megayears) has been suggested as a mechanism for the formation of wings in X-shaped radio galaxies (XRGs), to date no convincing case of reorientation has been found in any ...

Discovery of an unusual radio galaxy with a hybrid double-double and X-shaped morphology [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractWe report the discovery of the first ‘X’-shaped double-double radio galaxy (DDRG), MRC0929+164 (J0932+1611), from FIRST radio survey. The intersection angle of the lines of two pairs of radio lobes is around 20.6° for this object, much larger than other DDRGs.

On the origin of X-shaped radio galaxies [PDF]
Research in Astronomy and Astrophysics, 2012 After a brief, critical review of the leading explanations proposed for the small but important subset of radio galaxies showing an X-shaped morphology (XRGs) we propose a generalized model, based on the jet-shell interaction and spin-flip hypotheses. The most popular scenarios for this intriguing phenomenon invoke either hydrodynamical backflows and ...

Modelling X-shaped Radio Galaxies: Dynamical and Emission Signatures from the Back-flow model
Astronomy & Astrophysics, 2022 Context. Active galactic nuclei typically show the presence of radio jets ranging from sub-kiloparsec to megaparsec scales. Some of these radio galaxies show distortion in their jets, forming tailed or winged sources. X-shaped radio galaxies (XRGs) are a sub-class of winged sources, the formation mechanism of which is still unclear. Aims.

The optical spectra of X-shaped radio galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 X-shaped radio galaxies are defined by their peculiar large-scale radio morphology. In addition to the classical double-lobed structure they have a pair of low-luminosity wings that straddles the nucleus at almost right angles to the active lobes, thus giving the impression of an 'X'.

‘Normal’ Fanaroff-Riley type II radio galaxies as a probe of the nature of X-shaped radio sources [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 We present a multiwavelength radio study of a sample of nearby Fanaroff-Riley class II (FRII) radio galaxies, matched with the sample of known X-shaped radio sources in size, morphological properties and redshift, using new Giant Metrewave Radio Telescope (GMRT) data and archival data from the Very Large Array (VLA).

BOOK OF ABSTRACTS AND CONTRIBUTED PAPERS - International Meeting on Data for Atomic and Molecular Processes in Plasmas: Advances in Standards and ModellingHere we want to investigate X-shaped radio galaxy 3C 315, which is a FRII source, but it lies very close to the FRI/FRII borderline. We used publicly available data from Leahy’s atlas of double radio-sources and NASA/IPAC Extragalactic Database (NED) in ...
