  • Circular polarization in PKS 1519-273 

    Bennett, Wendy (2007-05-31)
    The intra-day variable BL Lac PKS 1519-273 exhibits variations at centimeter wavelengths in total intensity, linear polarization, and circular polarization. The variability is caused by scintillation due to the interstellar ...
  • The Faber-Jackson relation in Seyfert galaxies 

    Weinzirl, Timothy; Bennett, Wendy; Madland, Mark (2007-05-29)
    Seyfert galaxies, in which accretion onto a massive nuclear black hole acts as a powerful energy source, allegedly have bulges more luminous per unit mass than those in normal galaxies. We have tested this claim through ...
  • "Faber-Jackson relation in Seyfert galaxies" 

    Bennett, Wendy; Weinzirl, Timothy; Nelson, Charles H. (2005-06-23)
    Previous investigations have indicated that the bulges of Seyfert galaxies are more luminous than those in normal galaxies of the same mass. This may result if Seyfert bulges have experienced recent star formation, perhaps ...
  • Hubble space telescope imaging of seyfert galaxies 

    Bennett, Wendy; Madland, Mark; Weinzirl, Timothy; Nelson, Charles H. (2007-06-01)
    Recent searches for massive black holes in galactic nuclei show that they are common if not ubiquitous. Furthermore, there are important relationships between black hole mass and properties characterizing the size and ...
