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.

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.

GMRT Low-frequency Imaging of an Extended Sample of X-shaped Radio Galaxies [PDF]
The Astronomical Journal, 2019 Abstract We present a low-frequency imaging study of an extended sample of X-shaped radio sources using the Giant Metrewave Radio Telescope (GMRT) at two frequencies (610 and 240 MHz). The sources were drawn from a Very Large Array Radio Images of the Sky at Twenty-Centimeters (FIRST) selected sample and extend an initial GMRT study at ...

The Astrophysical Journal Supplement Series, 2023 Abstract X-shaped radio galaxies (XRGs) develop when certain extragalactic jets deviate from their propagation path. An asymmetric ambient medium (backflow model) or complex active galactic nucleus activity (jet-reorientation model) enforcing the jet direction to deviate may cause these structures.

Weak-lensing Analysis of the Complex Cluster Merger A746 with Subaru/Hyper Suprime-Cam
The Astrophysical JournalThe galaxy cluster A746 ( z = 0.214), featuring a double radio relic system, two isolated radio relics, a possible radio halo, disturbed V-shaped X-ray emission, and intricate galaxy distributions, is a unique and complex merging system.

BOOK OF ABSTRACTS AND CONTRIBUTED PAPERS - International Meeting on Data for Atomic and Molecular Processes in Plasmas: Advances in Standards and ModellingAbstractHere 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 order to investigate its flux density, as well as the spectral index distribution.
