Hydrodynamical backflow in X-shaped radio galaxy PKS 2014−55 [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT 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 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 ...

On the origin of X-shaped radio galaxies [PDF]
Research in Astronomy and Astrophysics, 2011 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.

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. Though several theoretical models have been proposed to explain their origin, there is currently not a general consensus on a formation scenario.Aims.We

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.

A Unified Framework for X-shaped Radio Galaxies
The Astrophysical Journal, 2020 Abstract We propose a radically different picture for X-shaped radio galaxies compared with existing models as transition objects between cold-mode accreting, low-spinning retrograde black holes and low-spinning prograde black holes. This model explains their smaller average black hole masses; their general aversion for cluster compared ...

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
