Hydrodynamical backflow in X-shaped radio galaxy PKS 2014−55 [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 We present MeerKAT 1.28 GHz total-intensity, polarization, and spectral-index images covering the giant (projected length l ≈ 1.57 Mpc) X-shaped radio source PKS 2014−55 with an unprecedented combination of brightness sensitivity and angular resolution ...

The X-shaped Radio Galaxy J0725+5835 is Associated with an AGN Pair [PDF]
Astrophysical Journal, 2022 X-shaped radio galaxies (XRGs) are those that exhibit two pairs of unaligned radio lobes (main radio lobes and wings). One of the promising models for the peculiar morphology is jet reorientation.

Discovery of X-shaped morphology of the giant radio galaxy 0503-286
Astronomy and Astrophysics, 2022 International audienceThe high surface-brightness sensitivity of the galactic and extragalactic all-sky mwa survey (GLEAM) image of the giant radio galaxy (GRG) 0503-28 at 70–230 MHz has revealed an inversion-symmetric bending of its two lobes, while ...

X-shaped radio galaxy 3C 223.1: A ‘double boomerang’ with an anomalous spectral gradient
Astronomy and Astrophysics, 2022 A comparison of the recent LOFAR 144 MHz map of the radio source 3C 223.1 (J094124.028+394441.95) with the VLA maps at 4.9 GHz and 8.3 GHz that we built based on archival data, establishes this X-shaped radio galaxy (XRG) as a singularly robust case ...

Multifrequency JVLA observations of the X-shaped radio galaxy in Abell 3670 [PDF]
Astronomy and Astrophysics, 2019 Context. X-shaped radio galaxies (XRGs) exhibit a pair of bright primary lobes and a pair of weak secondary lobes ("wings"), which are oriented with an angle that gives the structure a cross-like shape.

Restarting engine in an X-shaped radio galaxy [PDF]
Proceedings of From Planets to Dark Energy: the Modern Radio Universe — PoS(MRU), 2008 J2018-556, an X-shaped FR-I radio galaxy provides a unique opportunity to discuss the formation scenarios for the extended structures seen in this class of radio sources. An understanding of the origin of X-shaped source structures has important implications for radio galaxy models as well as black hole-black hole mergers.

Astrophysical Journal Letters, 2022 Abstract X-shaped radio galaxies (XRGs) produce misaligned X-shaped jet pairs and make up ≲10% of radio galaxies. XRGs are thought to emerge in galaxies featuring a binary supermassive black hole (SMBH), SMBH merger, or large-scale ambient medium asymmetry.

HYDRODYNAMIC MODELS OF RADIO GALAXY MORPHOLOGY: WINGED AND X-SHAPED SOURCES [PDF]
Astrophysical Journal, 2011 We present three-dimensional hydrodynamic models of radio galaxies interacting with initially relaxed hot atmospheres and explore the significant off-axis radio lobe structures which result under certain conditions. With a focus on the "winged" and "X-shaped" radio galaxy population, we confirm the importance of observed trends such as the connection ...
