Large-Scale Environment Properties of Narrow-Line Seyfert 1 Galaxies at z < 0.4

open access: yesFrontiers 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

open access: yes, 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

On black hole masses, radio-loudness and bulge luminosities of Seyfert galaxies [PDF]

open access: yes, 2001
We estimated black hole masses for 9 Seyfert 1 and 13 Seyfert 2 galaxies in the Palomar and CfA bright Seyfert samples using the tight correlation between black hole mass and bulge velocity dispersion.

The Radio Spectral Energy Distribution and Star-formation Rate Calibration in Galaxies [PDF]

open access: yes, 2016
We study the spectral energy distribution (SED) of the radio continuum (RC) emission from the Key Insight in Nearby Galaxies Emitting in Radio (KINGFISHER) sample of nearby galaxies to understand the energetics and origin of this emission.

The X-ray and radio structure of extragalactic jets

open access: yesВісник Астрономічної школи, 2011
The internal structure of jets from active galaxies is explored using the X-ray and radio data. The transverse intensity distributions of X-ray knots in jet are calculated and compared with corresponding intensity distributions for radio knots.

The core fundamental plane of B2 radio galaxies

open access: yes, 2009
The photometric, structural and kinematical properties of the centers of elliptical galaxies, harbor important information of the formation history of the galaxies.

Radio emission of Shakhbazian Compact Galaxy Groups [PDF]

open access: yes, 1999
Three hundred fifty three radio sources from the NRAO VLA Sky Survey (NVSS) (Condon et al. 1998) and the FIRST Survey (White et al. 1997}, are detected in the areas of 179 Shakhbazian Compact Groups (ShCGs) of galaxies.

The environments of high redshift radio galaxies and quasars: probes of protoclusters [PDF]

open access: yes, 2015
We use the GALFORM semi-analytical model to study high-density regions traced by radio galaxies and quasars at high redshifts. We explore the impact that baryonic physics has upon the properties of galaxies in these environments.
