The nature of the HE0450-2958 system
(Blackwell Publishing, 2005-11-10)
Magain et al. (2005) argued that the host galaxy of the quasar in HE0450-2958 is substantially under-luminous given the likely mass of its nuclear black hole. Using kinematical information from the spectra of the quasar ...
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 ...
Supermassive black hole mass measurements for NGC 1300 and NGC 2748 based on HST [Hubble Space Telescope] emission-line gas kinematics
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2005-05)
We present Space Telescope Imaging Spectrograph emission-line spectra of the central regions of the spiral galaxies NGC 1300 and NGC 2748. From the derived kinematics of the nuclear gas we have found evidence for central ...
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 ...
