The Origin of X-shaped Radio Galaxies: Clues from the Z-symmetric Secondary Lobes [PDF]
The 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 ...

Dynamical analysis of the complex radio structure in 3C 293: clues on a rapid jet realignment in X-shaped radio galaxies [PDF]
Astronomy & Astrophysics, 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 ...

Multifrequency JVLA observations of the X-shaped radio galaxy in Abell 3670 [PDF]
Astronomy & 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.

Orientation and size of the ‘Z’ in X-shaped radio galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2005 Some X-shaped radio galaxies show a Z-symmetric morphology in the less luminous secondary lobes. Within the scenario of a merger between two galaxies, each hosting a supermassive black hole in its center, this structure has been explained before: As the ...

Host Galaxies of X-Shaped Radio Sources [PDF]
, 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. Of particular interest are radio galaxies, the active galaxies emitting much of their radiation at radio wavelengths.

On the origin of X-shaped radio-sources: New insights from the properties of their host galaxies [PDF]
Astronomy & 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. We

Relationship between X-shaped radio sources and double-double radio galaxies [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractBoth the X-shaped radio galaxies and double-double radio galaxies (DDRGs) are suggested in the literature to be due to the binary-accretion disk interaction or to the coalescence of SMBBHs. These models suggest some relationship between the two types of radio sources. In this paper, we collected data from literatures for two samples of X-shaped

AChandraStudy of the Multicomponent X‐Ray Emission from the X‐shaped Radio Galaxy 3C 403 [PDF]
The 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

From 100 MHz to 10 GHz: Unveiling the spectral evolution of the X-shaped radio galaxy in Abell 3670 [PDF]
Astronomy & AstrophysicsX-shaped radio galaxies (XRGs) are characterised by two pairs of misaligned lobes: active lobes hosting radio jets and the wings. None of the formation mechanisms proposed thus far are able to exhaustively reproduce the diverse features observed among ...

X-shaped radio galaxies as observational evidence for the interaction of supermassive binary black holes and accretion disc at parsec scale [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 In the hierarchical galaxy formation model, today's galaxies are the product of frequent galaxy merging, triggering the activity of active galactic nuclei and forming a supermassive black hole binary.
