The gaseous environments of radio galaxies [PDF]
New Astronomy Reviews, 2002 X-ray emission traces the gaseous environments of radio sources. The medium must be present for jet confinement, but what are its influence on jet fuelling, dynamics, propagation, and disruption? The observational situation is both complicated and enriched by radio sources being multi-component X-ray emitters, with several possible regions of non ...

Large-Scale Environment Properties of Narrow-Line Seyfert 1 Galaxies at z < 0.4
Frontiers in Astronomy and Space Sciences, 2017 The large-scale environment is believed to affect the evolution and intrinsic properties of galaxies. It offers a new perspective on narrow-line Seyfert 1 galaxies (NLS1) which have not been extensively studied in this context before.

Radio Continuum Emission at 1.4 GHz from KISS Emission-Line Galaxies
, 2004 We have searched the Faint Images of the Radio Sky at Twenty centimeters (FIRST) and the NRAO VLA Sky Survey (NVSS) 1.4 GHz radio surveys for sources that are coincident with emission-line galaxy (ELG) candidates from the KPNO International Spectroscopic

Radio and optical orientations of galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We investigate the correlations between optical and radio isophotal position angles for 14302 SDSS galaxies with $r$ magnitudes brighter than 18 and which have been associated with extended FIRST radio sources. We identify two separate populations of galaxies using the colour, concentration and their principal components.

Optical and Radio Properties of Extragalactic Sources Observed by the FIRST and SDSS Surveys
, 2002 We discuss the optical and radio properties of 30,000 FIRST sources positionally associated with an SDSS source in 1230 deg$^2$ of sky. The majority (83%) of the FIRST sources identified with an SDSS source brighter than r=21 are optically resolved.

Radio Sources in the 2dF Galaxy Redshift Survey. I. Radio Source Populations [PDF]
, 1999 We present the first results from a study of the radio continuum properties of galaxies in the 2dF Galaxy Redshift Survey, based on thirty 2dF fields covering a total area of about 100 square degrees.

Pair-Matching of Radio-Loud and Radio-Quiet AGNs
Frontiers in Astronomy and Space Sciences, 2017 Active galactic nuclei (AGNs) are known to cover an extremely broad range of radio luminosities and the spread of their radio-loudness is very large at any value of the Eddington ratio.

HI absorption in Radio Galaxies [PDF]
Symposium - International Astronomical Union, 2002 Twenty-two powerful radio galaxies have been searched for HI absorption. We find the highest probability of detecting HI in absorption among narrow-line compact (or small) galaxies or galaxies with indication of richer interstellar medium (i.e. with ongoing or recent star-formation).
