The detection and number estimates of supermassive binary black holes (SMBBHs) provide important constraints on the hierarchical models for galaxy formation and...
A stellar disk perpendicular to the radio jet in B2 0034+25
CCD surface photometry of the radio galaxy B2 0034+25 is reported. Fourier analysis of the intensity variations along a set of closely spaced elliptical...
An accretion disc in the broad-line radio galaxy 3C 390.3?
The permitted broad component of the H-beta emission line in the broad-line radio galaxy (BLRG) 3C 390.3 presents a double-peaked structure similar to that seen...
An Extended Lyα Outflow from a Radio Galaxy at z = 3.7?
Spatially resolved observations of active galactic nuclei (AGN) host galaxies undergoing feedback processes are one of the most relevant avenues through which...
CCD surface photometry of the low-luminosity radio galaxies containing radio jets B2 0034 + 25 and B2 0206 + 35
CCD imaging of low-luminosity radio galaxies to detect the optical counterparts of radio jets is described in terms of the surface-photometry procedure and the...
CCD surface photometry of three low-luminosity radio galaxies containing radio jets
Results of CCD photometry of the three low-luminosity radio galaxies which contain jets at the kpc scale: B2 0836 + 29, B2 2116 + 26, and B2 2236 + 35 are...
Extended line emission in AGN: Looking at the central engine
The regions of high excitation gas detected around various Active Galactic Nuclei (AGN) are examined. The radiation emitted by the nucleus may be responsible...
Gas kinematics in the halo of the warm ULIRG PKS1345+12
We use long-slit spectra taken with the William Herschel Telescope on La Palma and high-resolution Hubble Space Telescope imaging to study the gas kinematic in...
