‘Normal’ Fanaroff-Riley type II radio galaxies as a probe of the nature of X-shaped radio sources [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 We present a multiwavelength radio study of a sample of nearby Fanaroff-Riley class II (FRII) radio galaxies, matched with the sample of known X-shaped radio sources in size, morphological properties and redshift, using new Giant Metrewave Radio Telescope (GMRT) data and archival data from the Very Large Array (VLA).

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

The X-shaped Radio Galaxy J0725+5835 is Associated with an AGN Pair [PDF]
The Astrophysical Journal, 2022 Abstract 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. To clarify this, we conducted a 5 GHz observation with the European VLBI Network (EVN) of XRG J0725+5835, which resembles the ...

Discovery of X-shaped morphology of the giant radio galaxy 0503-286 [PDF]
Astronomy & Astrophysics, 2022 The 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 maintaining a ∼200 kpc wide strip-like radio emission gap between their bent portions.

X-shaped radio galaxies: probing jet evolution, ambient medium dynamics, and their intricate interconnection [PDF]
Frontiers in Astronomy and Space SciencesThis review explores the field of X-shaped radio galaxies (XRGs), a distinctive subset of winged radio sources that are identified by two pairs of jetted lobes which aligned by a significant angle, resulting in an inversion-symmetric structure. These lobes, encompassing active (primary) and passive (secondary) phases, exhibit a diverse range of ...

Deciphering the Morphological Origins of X-shaped Radio Galaxies: Numerical Modeling of Backflow versus Jet Reorientation [PDF]
The Astrophysical Journal Supplement Series, 2023 Abstract X-shaped radio galaxies (XRGs) develop when certain extragalactic jets deviate from their propagation path. An asymmetric ambient medium (backflow model) or complex active galactic nucleus activity (jet-reorientation model) enforcing the jet direction to deviate may cause these structures.

A VLBA-uGMRT search for candidate binary black holes: Study of six X-shaped radio galaxies with double-peaked emission lines [PDF]
Monthly Notices of the Royal Astronomical SocietyABSTRACT Identifying methods to discover dual active galactic nucleus (AGN) has proven to be challenging. Several indirect tracers have been explored in the literature, including X/S-shaped radio morphologies and double-peaked (DP) emission lines in the optical spectra.
