A representative survey of the dynamics and energetics of FRII radio galaxies [PDF]
, 2017 We report the first large, systematic study of the dynamics and energetics of a representative sample of Fanaroff–Riley type II (FR II) radio galaxies with well-characterized group/cluster environments. We used X-ray inverse-Compton and radio synchrotron

Viewing Classical Radio Galaxies with the Upgraded GMRT and MeerKAT—A Progress Report
Galaxies, 2021 We present a progress report of a study of FR I and FR II radio galaxies. Several new morphological features in the radio emission are now revealed using the high (μJy) sensitivity reached in the range 550–1712 MHz, more than a factor of three, at the ...

FRIICAT: A FIRST catalog of FR II radio galaxies [PDF]
, 2017 With the aim of exploring the properties of the class of FR 0 radio galaxies, we selected a sample of 108 compact radio sources, called FR0 CAT , by combining observations from the NVSS, FIRST, and SDSS surveys.

The nuclear properties and extended morphologies of powerful radio galaxies: the roles of host galaxy and environment [PDF]
, 2017 Powerful radio galaxies exist as either compact or extended sources, with the extended sources traditionally classified by their radio morphologies as Fanaroff--Riley (FR) type I and II sources. FRI/II and compact radio galaxies have also been classified

A search for candidate radio supernova remnants in the nearby irregular starburst galaxies NGC 4214 and NGC 4395 [PDF]
Serbian Astronomical Journal, 2005 We present the results of a search for new candidate radio supernova remnants (SNRs) in the nearby starburst irregular galaxies NGC 4214 and NGC 4395 using archived radio observations made with the Very Large Array (VLA) at the wavelengths of 3.5 cm, 6 ...

Distant FR I radio galaxies in the Hubble Deep Field: implications for the cosmological evolution of radio-loud AGN [PDF]
, 2001 Deep and high resolution radio observations of the Hubble Deep Field and flanking fields have shown the presence of two distant edge-darkened FR I radio galaxies, allowing for the first time an estimate of their high redshift space density.

A closer view of the radio-FIR correlation: disentangling the contributions of star formation and AGN activity [PDF]
, 2010 We extend the Unified Radio Catalog, a catalog of sources detected by various (NVSS, FIRST, WENSS, GB6) radio surveys, and SDSS, to IR wavelengths by matching it to the IRAS Point and Faint Source catalogs.

COLA II - Radio and Spectroscopic Diagnostics of Nuclear Activity in Galaxies [PDF]
, 2002 We present optical spectroscopic observations of 93 galaxies taken from the infra-red selected COLA (Compact Objects in Low Power AGN) sample. The sample spans the range of far-IR luminosities from normal galaxies to LIRGs.

Discovery of giant radio galaxies from NVSS: radio and infrared properties [PDF]
, 2017 Giant radio galaxies (GRGs) are one of the largest astrophysical sources in the Universe with an overall projected linear size of ∼0.7 Mpc or more. The last six decades of radio astronomy research has led to the detection of thousands of radio galaxies ...
