From 100 MHz to 10 GHz: Unveiling the spectral evolution of the X-shaped radio galaxy in Abell 3670

Astronomy & Astrophysics
Context. X-shaped radio galaxies (XRGs) are characterised by two pairs of misaligned lobes: active lobes hosting radio jets and the wings. None of the formation mechanisms proposed thus far are able to exhaustively reproduce the diverse features observed among XRGs.

A VLBA-uGMRT search for candidate binary black holes: study of six X-shaped radio galaxies with double-peaked emission lines

Monthly Notices of the Royal Astronomical Society
ABSTRACT 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.

Origin of the double-peaked narrow emission-lines in the optical spectra of X-shaped Radio Galaxies

We investigate the X-shaped radio galaxies (XRGs) with optical double-peaked narrow emission (DPNEL) as potential hosts of dual or binary supermassive black holes (SMBHs). Using a sample of 187 XRGs selected from SDSS and DESI optical spectroscopic surveys, we check the AGN nature of both emission components using the BPT diagnostics of multiple ...
