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 ...
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 ...
High resolution studies of radio sources in the Hubble Deep and Flanking Fields
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2005-04)
Eighteen days of MERLIN data and 42 hours of A-array VLA data at 1.4 GHz have been combined to image a 10-arcmin field centred on the Hubble Deep and Flanking Fields (HDF and HFF). A complete sample of 92 radio sources ...
The supermassive black hole in the Seyfert 2 galaxy NGC 5252
(EDP Sciences: Astronomy & Astrophysics, 2005-02)
We present results from HST/STIS long-slit spectroscopy of the gas motions in the nuclear region of the Seyfert 2 galaxy NGC 5252. The observed velocity field is consistent with gas in regular rotation with superposed ...
