BIMA millimeter-wave observations of the core-jet and molecular gas in the FR I radio galaxy NGC 3801
(Astrophysical Journal, 2005-08-20)
We present BIMA 3 mm observations of the radio continuum source and the
molecular gas disk in the radio loud Fanaroff & Riley Type I (FR I) galaxy NGC
3801. We have detected a continuum source in the nucleus and determined ...
The evidence for jet-cloud interactions in a sample of high/intermediate-redshift radio galaxies
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2001-05)
We present detailed long-slit spectroscopic observations of a sample of four powerful
radio galaxies, with intermediate/high redshifts (0.47 < z < 0.81). The observations cover the rest-wavelength range 2600 °A- 6600 °A, ...
Equatorial scattering and the structure of the broad-line region in Seyfert nuclei: Evidence for a rotating disc
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2005-05)
We present detailed scattering models confirming that distinctive variations in polarization across the broad Halpha line, which are observed in a significant fraction of Seyfert 1 galaxies, can be understood in terms of ...
A NICMOS imaging study of high-z quasar host galaxies
(Blackwell Publishing, 2001-10)
We present the first results from a major Hubble Space Telescope programme designed
to investigate the cosmological evolution of quasar host galaxies from z~=2 to the
present day. Here we describe J and H-band NICMOS ...
PKS2250-41 and the role of jet-cloud interactions in powerful radio galaxies (full paper)
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 1999-02)
We present high resolution, long-slit spectra of the jet-cloud interaction in the powerful southern radio galaxy PKS2250-41.We have resolved the emission lines into two main kinematic components: a broad component (FWHM ...
Jet driven motions in the Narrow Line region of NGC1068
(Springer Netherlands: Astrophysics and Space Science, 1997-03)
We have obtained HST FOC f/48 long-slit spectroscopy of the inner 4" of the Narrow Line Region of NGC 1068 between 3500-5400A with a spectral resolution of 1.78A/pixel. At a spatial scale of 0.0287" per pixel these data ...
Spectroscopy of the near-nuclear regions of Cygnus A: Estimating the mass of the supermassive black hole
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2003-07)
We use a combination of high spatial resolution optical and near-IR spectroscopic data to make a detailed study of the kinematics of the NLR gas in the near-nuclear regions of the powerful, FRII radio galaxy Cygnus A ...
Seyferts on the edge: Polar scattering and orientation-dependent polarization in Seyfert 1 nuclei
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2004-05)
We have identified 12 Seyfert 1 galaxies that exhibit optical polarization spectra similar to those of Seyfert 2 galaxies in which polarized broad-lines are detected. We present new spectropolarimetric observations of 3 ...
High-resolution radio observations of Seyfert galaxies in the extended 12-micron sample - I. The Observations
(Blackwell Publishing, 2000-05)
We present 8.4 GHz VLA A–configuration observations of 87 sources from the
mid–infrared–selected AGN sample of Rush et al. (1993). These 0.25 arcsec resolution
observations allow elongated radio structures tens of parsecs ...
HI absorption in the gigamaser galaxy TXS 2226-184 and the relation between HI absorption and water emission
(American Astronomical Society, 2002-07-20)
We report on the discovery of H i in absorption toward the gigamaser galaxy TXS 2226-184 using the Very Large Array. The absorption appears to consist of two components—one with a width of 125 km s^-1 and one broader (420 ...
