  • Double Star Measurement 

    Morehouse, Daniel Walter (Drake University, 1902-05)
  • 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 ...
  • 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 ...
  • "Velocity Dispersion and Black Hole Mass in Seyfert 1 Galaxies" 

    Nelson, Charles H.; Green, Richard; Bower, Gary; Gebhardt, Karl; Weistrop, Donna (2003)
    Bulge stellar velocity dispersions, sigma, in Seyfert 1 galaxies are combined with the M_bh -- sigma relation to validate reverberation mapping as a means of determining nuclear black hole masses. Seyfert galaxies follow ...
