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

Monthly 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 ...

Wide-Field uGMRT band-3 Imaging of the Fields Around X-Shaped radio galaxies

Astronomy & Astrophysics
We present wide-field upgraded Giant Metrewave Radio Telescope (uGMRT) images of the fields around the X-shaped radio galaxies (XRGs) 4C32.25, 4C61.23, and MRC 2011–298 obtained at 400 MHz. The observations are calibrated using the extreme peeling method to account for direction-dependent effects across the field of view, as was previously applied to ...
