Simulations of Precessing Jets and the Formation of X-shaped Radio Galaxies [PDF]
The Astrophysical Journal, 2023 Jet precession is sometimes invoked to explain asymmetries in radio galaxy (RG) jets and “X/S/Z-shaped” RGs, caused by the presence of a binary black hole companion to the source active galactic nucleus or by accretion instabilities.

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 ...

HYDRODYNAMIC MODELS OF RADIO GALAXY MORPHOLOGY: WINGED AND X-SHAPED SOURCES [PDF]
The 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.

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 ...

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

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 which cannot be naturally explained by either the galactic merger or radio-lobe backflow scenarios, the two dominant models for these X-

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 A supermassive black hole binary may form during galaxy mergering. we investigate the interaction of the supermassive binary black holes (SMBBHs) and an accretion disk and show that the detected X-shaped structure in some FRII radio galaxies may be due ...

Shocking features in the merging galaxy cluster RXJ0334.2-0111 [PDF]
, 2016 © 2016 The Authors. We present a 66 ks Chandra X-ray observation of the galaxy cluster RXJ0334.2-0111. This deep observation revealed a unique bow shock system associated with a wide angle tail (WAT) radio galaxy and several intriguing substructures. The

CGCG 292-057 - a radio galaxy with merger-modulated radio activity
, 2012 We announce the discovery of a unique combination of features in a radio source identified with the merger galaxy CGCG 292-057. The radio galaxy both exhibits a highly complex, X-like structure and shows signs of recurrent activity in the form of double ...
