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.

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.

A DEEP CHANDRA OBSERVATION OF THE X-SHAPED RADIO GALAXY 4C +00.58: A CANDIDATE FOR MERGER-INDUCED REORIENTATION? [PDF]

open access: bronzeThe Astrophysical Journal, 2010
Although rapid reorientation of a black hole spin axis (lasting less than a few Myr) has been suggested as a mechanism for the formation of wings in X-shaped radio galaxies (XRGs), to date no convincing case of reorientation has been found in any XRG. Alternative wing formation models such as the hydrodynamic backflow models are supported by observed ...

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 ...

The Abundance of X-Shaped Radio Sources: Implications for the Gravitational Wave Background [PDF]

open access: yes, 2015
Coalescence of super massive black holes (SMBH's) in galaxy mergers is potentially the dominant contributor to the low frequency gravitational wave background (GWB).

The large scale magnetic field structure of the spiral galaxy NGC 5775 [PDF]

open access: yes, 2011
In order to better determine the large-scale 3D-structure of magnetic fields in spiral galaxies we present a Faraday rotation analysis of the edge-on spiral galaxy NGC 5775.

CGCG 292-057 - a radio galaxy with merger-modulated radio activity

open access: yes, 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 ...
