GMRT Low-frequency Imaging of an Extended Sample of X-shaped Radio Galaxies [PDF]

open access: bronzeThe Astronomical Journal, 2019
Abstract We present a low-frequency imaging study of an extended sample of X-shaped radio sources using the Giant Metrewave Radio Telescope (GMRT) at two frequencies (610 and 240 MHz). The sources were drawn from a Very Large Array Radio Images of the Sky at Twenty-Centimeters (FIRST) selected sample and extend an initial GMRT study at ...

X-shaped radio galaxies: probing jet evolution, ambient medium dynamics, and their intricate interconnection [PDF]

open access: goldFrontiers in Astronomy and Space Sciences
This 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 ...

Orientation and size of the ‘Z’ in X-shaped radio galaxies [PDF]

open access: bronzeMonthly 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 smaller galaxy spirals towards the common center, it releases gas to the ISM of the larger active ...

Host Galaxies of X-Shaped Radio Sources [PDF]

open access: green, 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.

X-shaped Radio Galaxies: Optical Properties, Large-scale Environment, and Relationship to Radio Structure [PDF]

open access: bronzeThe Astrophysical Journal, 2019
Abstract In pursuit of clues to the origin of “winged” or X-shaped radio galaxies (XRGs) we investigate the parent galaxies of a large sample of 106 XRGs for optical–radio axes alignment, interstellar medium, black hole mass, and large-scale environment.

Massive black hole binaries as sources of low-frequency gravitational waves and X-shaped radio galaxies [PDF]

open access: goldMonthly Notices of the Royal Astronomical Society
ABSTRACT We present the study of multimessenger signatures of massive black hole (MBH) binaries residing in the centres of galaxy merger remnants. In particular, we first focus on the gravitational wave background (GWB) produced by an ensemble of MBH binary inspirals in the frequency range probed by the Pulsar Timing Array (PTA ...

Discovery of an unusual radio galaxy with a hybrid double-double and X-shaped morphology [PDF]

open access: bronzeProceedings of the International Astronomical Union, 2012
AbstractWe report the discovery of the first ‘X’-shaped double-double radio galaxy (DDRG), MRC0929+164 (J0932+1611), from FIRST radio survey. The intersection angle of the lines of two pairs of radio lobes is around 20.6° for this object, much larger than other DDRGs.
