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.

On the Origin of X-Shaped Radio-Sources: New Insights From the Properties of Their Host Galaxies [PDF]
Astronomy and Astrophysics, 2002 A significant fraction of extended radio sources presents a peculiar X-shaped radio morphology: in addition to the classical double lobed structure, radio emission is also observed along a second axis of symmetry in the form of diffuse wings or tails ...

A Chandra Study of the Multicomponent X-Ray Emission From the X-Shaped Radio Galaxy 3C 403 [PDF]
Astrophysical Journal, 2005 We present results from a 49.4 ks Chandra ACIS-S observation of the nearby (z = 0.059) X-shaped FR type II (FR II) radio galaxy 3C 403. This is the first Chandra observation of an X-shaped radio galaxy, and one of the goals of this pioneering study is to

Starbursts and Black Hole Masses in X-Shaped Radio Galaxies: Signatures of a Merger Event? [PDF]
Astronomy and Astrophysics, 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.

The Origin of X-Shaped Radio Galaxies: Clues From the Z-Symmetric Secondary Lobes [PDF]
Astrophysical Journal, 2003 Existing radio images of a few X-shaped radio galaxies reveal Z-symmetric morphologies in their weaker secondary lobes that cannot be naturally explained by either the galactic merger or radio-lobe backflow scenarios, the two dominant models for these X ...

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'.
