Analytical and numerical galaxy-formation models indicate that active galactic nuclei (AGNs)
likely play a prominent role in the formation and evolution of galaxies. However, quantifying …

The properties of the host galaxies of a well-defined sample of 2215 radio-loud active
galactic nuclei (AGN) with redshifts 0.03< z< 0.3, defined from the Sloan Digital Sky Survey …

We have used narrow emission-line data from the new 7C Redshift Survey to investigate
correlations between the narrow-line luminosities and the radio properties of radio galaxies …

We present a study of the trends in luminosity, linear size, spectral index, and redshift of
classical double radio sources, from three complete samples selected at successively fainter …

Giant radio sources (GRSs) defined to be> 0.7 Mpc are the largest single objects in the
Universe and can be associated with both galaxies (GRGs) and quasars (GRQs). They are …

We present the results of multi-epoch global VLBI observations of the Compact Symmetric
Object (CSO), 0710+ 439 at 5 GHz. Analysis of data spread over 13 years shows strong …

The inner parts of an accretion disk around a spinning black hole are forced to align with the
spin of the hole by the Bardeen-Petterson effect. Assuming that any jet produced by such a …

The broad-bandwidth capabilities of next generation telescopes such as the Jansky Very
Large Array (JVLA) mean that the spectrum of any given source varies significantly within …

Jellyfish galaxies have long tails of gas that is stripped from the disk by ram pressure due to
the motion of galaxies in the intracluster medium in galaxy clusters. Here, we present the …

We compare two temporal properties of classical double radio sources:(1) radiative lifetimes
of synchrotron-emitting particles and (2) dynamical source ages. We discuss how these can …
