High-resolution radio observations of Seyfert galaxies in the extended 12-micron sample - II. The properties of compact radio components

, 2001
We discuss the properties of compact nuclear radio components in Seyfert galaxies from the extended 12-micron AGN sample of Rush et al.(1993). Our main results can be summarised as follows.

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 ...

Understanding the Fanaroff-Riley radio galaxy classification

, 2012
The simple, yet profoundly far-reaching classification scheme based on extended radio morphologies of radio galaxies, the Fanaroff-Riley classification has been a cornerstone in our understanding of radio galaxies.

The vertical disk structure of the edge-on spiral galaxy NGC 3079 [PDF]

NGC 3079 is an edge-on SB(s)c galaxy at a redshift of 1225 km/s relative to the Local Group. Earlier researchers found a spectacular 'figure-eight' radio structure aligned along the minor axis of the galaxy, centered on the nucleus, and extending 3 kpc ...

Stormy weather in 3C 196.1: nuclear outbursts and merger events shape the environment of the hybrid radio galaxy 3C 196.1

, 2018
We present a multi-wavelength analysis based on archival radio, optical and X-ray data of the complex radio source 3C 196.1, whose host is the brightest cluster galaxy of a $z=0.198$ cluster. HST data show H$\alpha$+[N II] emission aligned with the jet 8.

Evidence for In - Situ Acceleration of Relativistic Particles in the Wings of X-shaped Radio Galaxies

The Astrophysical Journal
Abstract We report evidence for in - situ acceleration/reacceleration of relativistic particles in 11 radio wings out of a total of 68 wings sufficiently well-resolved for spectral mapping, which belong to our sample of 40 X-shaped ...
